Abstract: Polygon boundaries with text label indicating the relative ground-shaking amplification rating of each polygon.
Statement: Manual digitising from published 1:250,000 geological maps with additional interpretation and synthesis. The information presented in this layer and accompanying Client Report 33596B.10 (WRC Technical Document TR96/17) was developed by the Institute of Geological and Nuclear Sciences for Waikato Regional Council as a regional snapshot of Ground shaking susceptibility. The data are not suitable for and should not be used in place of detailed investigations into any particular engineering, town planning or infrastructure project.
Other Information: Data is presented as digital polygon boundaries with a text label, which indicates the relative ground-shaking amplification rating of each polygon. Positional accuracy is Low; 80% well-known points located with +/- 250 m of actual position. The source maps were drafted in September 1996. The information can be considered to be current. Modifications will occur as peer reviewed research becomes available. Research was undertaken up to 1996 by IGNS. Data aquisition from Manual digitising from published 1:250,000 geological maps with additional interpretation and synthesis. Reviewers at IGNS verified data after capture. This is the best available source information was used but data is generalised by virtue of its scale (1:250,000) and age (1960 up until 1993). Data should not be used at a scale beyond 1:250,000. Logical consistency is high Data was supplied in both published (paper map) form, and as a digital GIS graphics file. Data was supplied in both published (paper map) form, and as a digital GIS graphics file For related information: Institute of Geological & Nuclear Sciences Client Report 33596B.10 (available as WRC Technical Report # TR96/17)). WRC Policy Series 97/12 ‘Earthquake Risk Mitigation Plan’. Also see EW DOCS# 734315. Attribute accuracy is High. All polygons have a single attribute rating from A-D. Extract from Beanland, S., Drummond, G., Huber, P., Hull, A., and Townsend, T., 1996: Earthquake Hazard Analysis of Waikato Regional Council Area. Client Report 1996/3359B.10, Institute of Nuclear and Geological Sciences Limited, Lower Hutt.] 4.1 Geological units and hazard zones Geological materials in the Environment Waikato Region have been classified and mapped into four units for this study. These units are used to define hazard zones. It is important to note that the data have been both compiled and digitised at 1:250,000 scale, unlike the active fault data which were compiled and digitised at 1:50,000 scale. The accuracy of the hazard zone boundaries is therefore much less than that of the fault locations. The four units, in order of decreasing hazards, are: UNIT A: Holocene (<10,000 yrs) fluvial, lake, fan and swamp deposits and near coastal estuarine and beach deposits. Commonly high in volcanic ash content. These deposits comprise unconsolidated, very soft to stiff intermixed peat, clay, silt, ash, sand and gravel. The groundwater table generally very high. May include liquefiable layers. Critical thickness of sediments 2-15 m. MOST HAZARDOUS. Amplification of approximately two MMI units and/or settlement and liquefaction common. UNIT B: Quaternary (< 2.5 Myr) fluvial and marine terrace deposits, lignite, dunesand, pumice alluvium and ignimbrite flows. Unsaturated, slightly weathered, unconsolidated gravel, ash and sand. QUITE HAZARDOUS. Amplification of approximately one MMI unit common. UNIT C: Tertiary (< 75 Myr) sandstone, siltstone, mudstone, coal measures, limestone, and conglomerate. Includes volcanic rocks of various ages. Gravels dense to very dense. Rock strength weak to moderately strong. NOT VERY HAZARDOUS, except that fine grained rocks are particularly prone to slumping and landsliding, especially if saturated and/or denuded of vegetation cover. UNIT D: Basement rocks, (>75 Myr), greywacke (generally indurated, well bedded, sandstones and siltstones, moderately to highly deformed) and minor schist. Weak to very strong. LEAST HAZARDOUS..

Hierarchy Level: feature Hierarchy Level Name:Feature of HAZARDS - Regional Hazards Portal
Abstract: Areas in the Waikato District that are defended from river flooding by flood protection structures up to a specified design event.
Statement: Defended areas are those that are defended from flooding by structural defences such as stopbanks or floodwalls. These areas are not defended from all flood events. They are defended from flooding from a specified water course up to a specified design flood event. The water course defended from and the design flood event (described by the event frequency as an AEP) are provided in the attribute information as ‘Water Course’ and ‘AEP’ respectively. The data is presented as vector polygon data and was created for use in the Waikato District Plan Review (2019).

Although the defended areas are defended by most flood events (depending on their level of protection), they still have the potential to flood. Defended areas may flood due to a larger than design event, or due to failure of a structural defence. This risk that remains is known as "residual risk". The Waikato Regional Policy Statement and Practise note (https://discover.wairc.govt.nz/otcs/llisapi.dll?func=ll&objaction=overview&objid=12000091) includes policies and methods about residual risk, including that residual risk zones shall be identified in District Plans.
Other Information: For the Waikato District, defended areas were determined using the following process:
For all stopbanks or defended areas outside of the Huntly Urban area, the defended area was defined using existing Direct Benefit Rating layers (GIS_ALL.RACS_RATE_WAIKWAIP_DIR_BENEFIT; under “RACS – Rating Scheme – Waikato-Waipa – GIS Layer” in the Data Catalogue), and included an expert review to ensure correct benefit areas were used.
For all stopbanks or defended areas within the Huntly Urban area, the defended area is defined as ground areas (based on 2007/2008 LiDAR) at or below the Design Flood Level of the relevant stopbank reach.

Statement: 2D flood extent as interpolated from a Mike 21 1D model on to a LiDAR derived topography using WaterRide Software. This information is created by inferring the 1959 flood protection scheme design 1% AEP 1D flood model over the adjacent floodplain to create a 2D representation. There may be some inaccuracies and errors associated with this method. The modelling does not include the predicted effects of climate change on rainfall intensity and sea level rise. These maps do not show internal ponding in overbank areas which is likely in an event. Where stopbanks are overtopped, full flooding is shown. The model also only relates to the main channel, with many tributaries and some overbank areas not included. The presence of a hazard does not guarantee the existence of such a hazard, nor does the lack of information preclude the existence of a hazard or risk. Waikato Regional Council accepts no liability or otherwise resulting from hazards or knowledge of hazards. The information is correct as at 16 November 2016. Some small internal polygons that weren't part of the model were added back in using an ArcGIS model. See discover document below.

The presence of a hazard does not guarantee the existence of such a hazard, nor does the lack of information preclude the existence of a hazard or risk. Waikato Regional Council accepts no liability or otherwise resulting from hazards or knowledge of hazards. The information is correct as at 16 November 2016.
Other Information: Some small internal polygons that weren't part of the model were added back in using an ArcGIS model. See discover document below. see http://discover.wairc.govt.nz/otcs/llisapi.dll?func=ll&objaction=overview&objid=9717200

Abstract: Modelled water depths for the hypothetical situation of probable maximum flood, resulting from a Karapiro dam break (assumes instantaneous, total removal of the dam, which is an extreme scenario).
Statement: This data is presented as raster data which shows the modelled water depths for the hypothetical scenario of a Karapiro dam break flood (rainy day scenario/probable maximum flood). This data was produced as part of a report commissioned by Mercury Energy (then Mighty River Power) in 2012 from an external expert (DHI Water and Environmental Limited). This is part of ongoing prudent emergency response preparedness, with at least seven related and detailed studies undertaken since 1989. The report models water movement in the hypothetical situation of a dam break, and assumes an instantaneous, total removal of the dam, which is an extreme scenario. Although the underlying assumption of this report is of sudden complete removal of the dam, it does not imply that the dam is unsafe in any way.
For the modelling, a hybrid one- and two-dimensional modelling approach was chosen. The two-dimensional method was used where over-bank flow is likely, and the one-dimensional method was used where the flood wave is expected to be confined within the channel. Mercury Energy should be contacted for any further information, including to request the modelling report.

Abstract: River flood depth for the 1% annual exceedance probability (AEP) event for a number of rivers and streams, derived from local flood modelling. Does not contain depth values, only depth classes, thus is to be used for mapping purposes.
Statement: River flood depth for a 1% annual exceedance probability (AEP) event, derived from 2D local flood modelling. To determine the potential flood depth, the flood level data was reclassified into flood depth above ground level (from LiDAR data) in meters. Data is presented as polygons which show flood depth classes (not values), and should be used for mapping purposes. Attribute information includes the year the modelling was completed (from ~2006 onwards). Models have incorporated the best available information at the time of their creation, generally including (but not always) LiDAR data, and flood event survey assessments. A climate change component is generally included in the modelling and will likely be based on the best available MfE guidance from the period of modelling. All flood depth information takes into account the presence of WRC-managed stopbanks and floodwalls, with the exception of Tararu and Te Puru (which have been modelled using a “stopbanks down” approach). The LiDAR data is converted to a grid which has limitation when assessing small stream channels and topographic features such as ridges. This may lead to minor discrepancies in water flows which may lead to limitations in defining flood extents. Internal drainage such as storm water systems, culverts, piping etc, are generally not included in the modelling. Depending on how the model is configured, they often only consider the main watercourse, so flooding of minor channels, tributaries, ponding and coastal inundation may not be represented by the flood extent. This information is not intended to replace more detailed hydrogeological and survey data required for Building Consents or Resource Consents. The information shown is current as of the time of modelling, including assumptions around climate change and hydrology etc. Note that this is a “live” dataset and further additions will be made as and when available and verified.
Other Information: For further information, including the model limitations for a particular area, please contact the Regional Hazards team or Technical Services team.

Abstract: River flood hazard classification for a number of rivers and streams, derived from local flood modelling. REPLACES the obsolete feature HAZ_FLOOD_HAZ_MOD_THAMES_CORO.
Statement: River flood hazard classification for a 1% annual exceedance probability (AEP) event, derived from the (2D) modelled flood depth and flood speed data for a number of rivers and streams. To determine the potential flood hazard classification a matrix was designed combining both flood depth and flood speed. The hazard classification has been divided into three levels of river flood hazard based on the likely impact on people, property and surrounding environment. These are: 1. Low- The combined depth and speed of floodwaters are unlikely to impair the maneuverability or stability of the average person and damage to property is likely to be non- structural and mainly due to inundation and deposition of sediment. 2. Medium- The combined depth and speed of floodwaters are likely to start to impede the maneuverability or stability of the average person and damage to property is unlikely to be structural provided that weak points such as windows and doors are retained above flood level. 3. High- The combined depth and speed of floodwaters are likely to significantly impede the maneuverability or stability of the average person and damage to property is likely to be widespread and structural, including instances where building have been raised above the flood level. In addition, there is also Defended which covers areas defended from river flood hazards (by stopbanks or other protection measures). Data is presented as polygons showing potential flood hazard. Attribute information includes the year the modelling was completed (from 2006 onwards). Models have incorporated the best available information at the time of their creation, generally including (but not always) LiDAR data, and flood event survey assessments. A climate change component is generally included in the modelling and will likely be based on the best available MfE guidance from the period of modelling. Note that for Grahams Creek a climate change component is not included for the flood hazard classification, due to the design of the flood scheme to current climate only as a result of community consultation. The LiDAR data is converted to a grid which has limitation when assessing small stream channels and topographic features such as ridges. This may lead to minor discrepancies in water flows which may lead to limitations in defining flood extents. Internal drainage such as storm water systems, culverts, piping etc, are generally not included in the modelling. Depending on how the model is configured, they often only consider the main watercourse, so flooding of minor channels, tributaries, ponding and coastal inundation may not be represented by the flood extent.

Abstract: Tsunami modelling for the eastern Coromandel and Firth of Thames by eCoast Limited which shows tsunami depth for a maximum credible event scenario. Does not contain depth values, only depth classes, thus is to be used for mapping purposes.
Statement: Tsunami inundation depth for a maximum credible event scenario, derived from tsunami modelling for the eastern Coromandel (published between 2013 and 2017) and for the Firth of Thames (published 2019) by eCoast Limited. For the eastern Coromandel, this scenario is a near-source tsunami resulting from an earthquake at the Tonga-Kermadec Trench. For the Firth of Thames, this scenario is regarded as a local-source tsunami resulting from an earthquake on the off-shore section of the Kerepehi Fault. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as polygons which show tsunami inundation depth classes (not values), and should be used for mapping purposes. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai. This dataset can be used to guide evacuation planning routes.

Abstract: Modelled Tsunami Hazard for a Maximum Credible Event for eastern Coromandel and Firth of Thames.
Statement: Tsunami hazard for a maximum credible event scenario, derived from tsunami modelling for the eastern Coromandel (published between 2013 and 2017) and for the Firth of Thames (published 2019) by eCoast Limited. This data illustrates the expected tsunami hazard for a modelled Maximum Credible Event scenario. For the eastern Coromandel, this scenario is a near-source tsunami resulting from an earthquake at the Tonga-Kermadec Trench. For the Firth of Thames, this scenario is regarded as a local-source tsunami resulting from an earthquake on the off-shore section of the Kerepehi Fault. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as polygons which show tsunami hazard, classified as low, medium or high hazard. The hazard classification is the same used for flood hazards. This tsunami hazard data was derived from combining tsunami depth and tsunami speed data. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai. This dataset can be used to guide evacuation planning routes.

Abstract: Inundation extent polygons that have been mapped along the Kaiaua Miranda coastline, based on a desktop study of pasture burn captured in aerial imagery (early 2018) following the 4-6 January 2018 storm surge event.
Statement: This data is presented as vector polygon data which shows the inundation extent along the Kaiaua Miranda coastline from the 4-6 January 2018 storm surge event, as represented by pasture burn (dead pasture due to salt water inundation). The polygons were mapped based on pasture burn shown on aerial imagery that was captured soon after the event, in early 2018. The digitisation of the pasture burn was completed by the Waikato Regional Council (WRC) Regional Hazards Team. Where the pasture burn lines were unclear, LiDAR (elevation) data and the surveyed inundation data was used to assist with mapping. The inundation extent has often not been mapped in built up areas due to the difficulty of identifying pasture burn in these areas. The lack of a desktop inundation extent polygon covering an area does not necessarily mean that inundation did not occur in this area. The presence of a desktop inundation extent polygon does not necessarily mean that inundation did occur in this area.

Abstract: Surveyed points that show the inundation extent for the 4-6 January 2018 storm surge event at locations along the Firth of Thames and Coromandel Peninsular.
Statement: This data is presented as vector point data which shows the surveyed inundation extent for the 4-6 January 2018 storm surge event. Attribute information includes the elevation of the ground level at each survey point (in various datums) – these elevations do not necessarily represent the maximum level that the water reached, although they may provide an indication. Post event data collection was undertaken by a variety of field teams and then collated into a mapped area by Waikato Regional Council (WRC). These were collected by the WRC Environmental Monitoring (EM) team, who visited some rural sites and mapped burnt pasture lines. The WRC EM team also visited sites along the western Coromandel Coast mapping inundation extent points in townships where possible from Port Charles to Tararu. This was combined with some anecdotal water level reports collected by Thames Coromandel District Council during their post-event inspections. This data shows the significant amount of damaging inundation along the Thames Coast Road, as well as substantial impacts to residential (particularly at Waiomu, Te Puru and Kaiaua), and rural (Kaiaua/Miranda Coast) areas. Land elevations that the inundation affected varied across the area dependent on local topography and hydrodynamic effects. Surveyed debris/burnt pasture lines caused by inundation from the event varied in average elevation from RL 1.2 m on the southern Kaiaua/Miranda Coast to 3.0m across the Hauraki Plains. The maximum elevation of the surveyed inundation lines was at 5.7 m (TVD) at Ngarimu and Whakatete Bay, if accurately identified this is likely due to wave effects.

Abstract: **Previously RACS_FLOOD_HAZARD** The Regional Scale Flood Hazard data is polygon features of areas in the Waikato Region that may be susceptible to flooding, based on varying sources of information. Intended to be used to indicate where further flood hazard investigation may be required.
Statement: The data is a compilation of flood hazard information which is sourced from a combination of; previous event information (photos and aerial imagery, anecdotal information, post-event surveys), flood modelling, flood protection and drainage scheme information, and elevation data. Data is presented as polygons which represent susceptibility to flooding, with attribute information indicating type of flooding, historical floods, data reference and quality, etc. The data attribute also includes "FLOOD_HAZARD_ID", which is an ID number that corresponds to text files with additional information, available internally in Discover folder # 30 07 10. This data should be viewed in conjunction with flood protection and land drainage asset data (found in GIS_ALL.RACS...) This is for general public information on susceptibility to flooding in the Waikato Region, and should be used to indicate where further investigation may be required. It is important to note that this information is not suitable to use for building or resource consent applications as it is not suitable to be viewed at a property scale.
Other Information: Regarding data accuracy, the least accurate data is from polygons plotted on 1:50,000 topo map then transferred to this dataset. The most accurate data is derived from flood modelling. Information on data accuracy can be seen in the attributes. Due to the low accuracy of much of the data, it should not be viewed beyond a 1:50,000 scale, and ideally not using aerial photography as the base layer. Collation of data has occurred from November 1996 to April 2019. The information shown is current as of 1 April 2019. Note that this is a “live” data set and further additions will be made as and when available and verified. Refer to DOCS# 951493 and 971022 for data quality. Note that the verification process used has determined the level of accuracy. Data were collected by multiple people over time and originally collated in Excel spreadsheets. These were output to MS Access to create the draft GIS layer and edited for consistency of format and style together with removal of obvious typographic errors and such like. Logical checks were carried out to ensure that valid attribute values are used where possible – such as valid territorial authority names, and document references. Basic QA in the GIS included topological verification (all polygons close etc.) and that required attribute fields are populated. Spatial and aspatial data were finally loaded into Oracle (Spatial) to form the corporate GIS layer. Data form is in GIS Layers and MS Word Documents. The data is stored in Waikato Regional Council's corporate Oracle (Spatial) database as Features that can be loaded using WRC’s GIS, and that can be accessed by any other Oracle or SQL-based application.

Abstract: Point locations that represent available sea level scenario information for the Waikato coastline. Attributes include indicative sea levels for each location for; MHWS, max tide, lower and upper storm tide range, for the current climate and with 0.5 and 1 m sea level rise. Designed for use in Waikato Regional Councils Coastal Inundation Tool.
Statement: This dataset comprises point locations (vector point data) that represent where sea level scenario information is available for the Waikato coastline. Attributes include indicative sea levels for each location for; MHWS, max tide, lower and upper storm tide range, for the current climate and with 0.5 and 1 m sea level rise. The data was created for use in Waikato Regional Councils Coastal Inundation Tool, in conjunction with GIS_IMAGE.COASTAL_INUNDATION_MOSAIC. The sea level scenarios in this dataset are based on NIWA’s national tide model and the information in the 2014 NIWA report, “Analysis of Whitianga, Tararu and Kawhia sea-level records to 2014": https://waikatoregion.govt.nz/assets/PageFiles/41257/3460508%20NIWA%20report.pdf and are derived from the (internal) table: https://discover.wairc.govt.nz/otcs/llisapi.dll?func=ll&objaction=overview&objid=3819631
Other Information: More information on how the scenarios were generated and the limitations of the scenarios can be found in Section 3 of the Coastal Inundation Tool User Guide: https://www.waikatoregion.govt.nz/assets/WRC/Services/regional-services/hazards-and-emergency-management/coastal/Coastal-Inundation-Tool-V2-User-Guide.pdf

Abstract: HAZARDS - Model boundaries for Maximum Credible Event tsunami modelling for eastern Coromandel and Firth of Thames
Statement: Model boundaries for the maximum credible event tsunami modelling carried out for the eastern Coromandel (published between 2013 and 2017) and the Firth of Thames (published 2019) by eCoast limited. The model boundaries show which areas were included in the modelling. Areas that are outside of the tsunami model boundaries have not been modelled, but may still be at risk of tsunami inundation. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as line data. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai.

Abstract: Individual layers representing coastal inundation (flooding) for different sea levels, at 0.2 m increments up to RL 5 m (Moturiki Vertical Datum 1953). Designed for use in Waikato Regional Councils Coastal Inundation Tool.
Statement: This dataset comprises individual layers representing coastal inundation depths for specific sea levels. The sea levels used are in 0.2 m increments and range from 0.8 m to 5.0 m (relative to Moturiki Vertical Datum 1953). Note that the first mapped water level for all locations shows the area that is likely to be inundated with a high tide (generally 0.2 m below the MHWS water level). All higher mapped water levels only show areas that would not normally be inundated by a high tide. Data is presented as raster files which show inundation depth for connected areas (where water could flow directly to the sea) and disconnected areas (below or at the water level but may have no direct flow path to the sea). Disconnected areas may still be affected by coastal inundation in some way, e.g. via groundwater.
Other Information: The coastal inundation layers were generated using a LiDAR derived Digital Elevation Model (DEM), which is generally accurate to around ±0.2 m vertically. The LiDAR survey does not identify all features that allow water to flow through (e.g. culverts), or are barriers to water flow (e.g. flood walls or sheet piling). Thus, manual modification of the DEM for specific areas was undertaken to ensure the DEM generally represented the hydraulic regime, especially for areas with flood protection, such as the Hauraki Plains. Therefore, the green disconnected inundation areas may or may not be ‘real’ and could actually be connected inundation areas. The disconnected inundation areas should still be regarded as areas that could be affected in some way by coastal inundation. More information on the limitations of the data is available in the Coastal Inundation Tool User Guide: https://www.waikatoregion.govt.nz/assets/WRC/Services/regional-services/hazards-and-emergency-management/coastal/Coastal-Inundation-Tool-V2-User-Guide.pdf

Abstract: River flood depth for the 1% annual exceedance probability (AEP) event for a number of rivers and streams, derived from local flood modelling. Contains depth values, thus to be used for technical purposes.
Statement: River flood depth for a 1% annual exceedance probability (AEP) event, derived from 2D local flood modelling. To determine the potential flood depth, the flood level data was reclassified into flood depth above ground level (from LiDAR data) in meters. Data is presented as integer raster files showing potential flood depth, and can be used for technical analysis. Raster VALUE field = depth m. Attribute information includes the year the modelling was completed (from ~2006 onwards). Models have incorporated the best available information at the time of their creation, generally including (but not always) LiDAR data, and flood event survey assessments. A climate change component is generally included in the modelling and will likely be based on the best available MfE guidance from the period of modelling. All flood depth information takes into account the presence of WRC-managed stopbanks and floodwalls, with the exception of Tararu and Te Puru (which have been modelled using a “stopbanks down” approach). The LiDAR data is converted to a grid which has limitation when assessing small stream channels and topographic features such as ridges. This may lead to minor discrepancies in water flows which may lead to limitations in defining flood extents. Internal drainage such as storm water systems, culverts, piping etc, are generally not included in the modelling. Depending on how the model is configured, they often only consider the main watercourse, so flooding of minor channels, tributaries, ponding and coastal inundation may not be represented by the flood extent. This information is not intended to replace more detailed hydrogeological and survey data required for Building Consents or Resource Consents. The information shown is current as of the time of modelling, including assumptions around climate change and hydrology etc. Note that this is a “live” dataset and further additions will be made as and when available and verified.
Other Information: For further information, including the model limitations for a particular area, please contact the Regional Hazards team or Technical Services team.

Abstract: River flood depth for the 1% annual exceedance probability (AEP) event for Tararu and Te Puru, derived from local flood modelling using a "stopbanks down" scenario. Contains depth values, thus can be used for technical purposes.
Statement: River flood depth for a 1% annual exceedance probability (AEP) event for Tararu and Te Puru, derived from 2D local flood modelling. This modelling was done using a "stopbanks down" approach, i.e. the flooding that would occur if there were no stopbanks. In reality, most of Tararu and Te Puru are defended from a 1% AEP river flood event by the flood scheme in place. To determine the potential flood depth, the flood level data was reclassified into flood depth above ground level (from LiDAR data) in meters. Data is presented as integer raster files showing potential flood depth, and can be used for technical analysis. Raster VALUE field = depth m. Attribute information includes the year the modelling was completed (2013).

Abstract: Tsunami modelling for the eastern Coromandel and Firth of Thames by eCoast Limited which provides the tsunami depth data for a maximum credible event scenario. Contains depth values, thus to be used for technical purposes.
Statement: Tsunami inundation depth for a maximum credible event scenario, derived from tsunami modelling for the eastern Coromandel (published between 2013 and 2017) and for the Firth of Thames (published 2019) by eCoast Limited. For the eastern Coromandel, this scenario is a near-source tsunami resulting from an earthquake at the Tonga-Kermadec Trench. For the Firth of Thames, this scenario is regarded as a local-source tsunami resulting from an earthquake on the off-shore section of the Kerepehi Fault. The modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. Data is presented as a raster file which provides tsunami inundation depth, and can be used for technical analysis. For the eastern Coromandel, the areas modelled include Whitianga, Mercury Bay, Cooks Beach, Hahei, Hot Water Beach, Kennedy Bay, Whangapoua, Matarangi, Kuaotunu, Opito Bay, Whangamata, Whiritoa, Pauanui and Tairua. For the Firth of Thames, the areas modelled include Colville, Coromandel, Manaia, Tapu, Te Puru, Thames, Miranda, and Whakatiwai. This dataset can be used to guide evacuation planning routes.
