Name: Flood Hazard (High)

Display Field: HighFloodHazardDataSource

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Rule used to identify high hazard areas:Either: - the water depth is greater than 1 m, or- the water depth (in metres) x the water velocity (in metres per second) is equal to or greater than 1.High rainfall hazard areas were identified using the two raster: SD_500_8p5_WD (depth) and SD_500_8p5_HZ (depth*velocity)(Location: ArcGIS 10.9.1 SD\Feature\geodatabases\DHI_RainOnGrid.gdb; Source: DHI New Zealand) High river hazard areas were identified using the two raster: FINAL_500yr_ARI_Q_1000cumecs_MAX_VEL0.asc (depth) and FINAL_500yr_ARI_Q_1000cumecs_MAX_DEP0.asc (velocity) (Location: Flood 200yr_500yr\Additional Data_SelwynRiver_ECan\FINAL_500yr_ARI_Q_1000cumecs; Source: ECAN)More information can be found at: https://apps.canterburymaps.govt.nz/SelwynNaturalHazards/or the following reports: Selwyn River / Waikirikiri Floodplain Investigation and DHI Water and Environment Ltd report – Regional Policy Statement Modelling for SDC – District Plan
