Abstract:<\/SPAN><\/P>

The purpose of this investigation was to model the flood effects across the District for the 100, 200 and 500 ARI (Annual Recurrence Interval) rain events. The maximum flood depths and corresponding maximum velocities would be used to generate a map of flood hazards. The flood hazard maps would be used in Council planning documents and form a layer on the Council GIS to be used in Council LIMs.<\/SPAN><\/P>

Full Catchment Models have been produced that model the full district north and south of the Ashley River. Only the Lees Valley catchment upstream of Ashley Gorge has not been included due to insufficient ground data being available. <\/SPAN><\/P>

Lineage:<\/SPAN><\/P>

Flood modelling has been completed for all areas of the Waimakariri District with the exception of Lees Valley and flood exclusion zones (the flood exclusion zones are areas where the modelling has not been undertaken as these areas have recently had their land levels altered). Efforts have been made to update the Flood Modelling for new and proposed development areas, however the modelling may not be accurate in all areas where development has occurred since 2014.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "Coastal flood modelling results.", "title": "CoastalFlooding200yrDepth", "tags": [ "Coastal Flood Model", "Flooding Hazard", "Waimakariri District" ], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 150000000, "maxScale": 5000, "spatialReference": "", "accessInformation": "DHI, WDC, & ECAN", "licenseInfo": "
