Extreme wave events can damage marine ecosystems and affect coastal infrastructure, ocean-based industries, and other human activities. Changing wave characteristics can have impacts on natural systems, as most coastal and near-shore biological communities can be damaged or destroyed by extreme wave action (Ummenhofer & Mehl, 2017). In another...

Service Description: Exposure – the degree to which the shoreline is exposed to wave and swell energy. This variable is further described by 4 attributes: sheltered, exposed, sheltered pocket beach and exposed pocket beach. The geomorphic variables were sourced from the New Zealand coastal type classification scheme and GIS mapping procedures that were...

The High Intensity Rainfall Design System (HIRDS) provides estimates of high intensity rainfall at ungauged locations for a range of return periods and event durations. These surfaces can be used for design storm assessment and in the design of flood protection works and other waterway structures. They can also be used for flood modelling, including flood...

Service Description: The Coastal Sensitivity Index (CSI) provides a snapshot of the potential sensitivity of the New Zealand soft shore coastline to coastal inundation (coastal flooding) and coastal change (erosion and accretion) due to future climate change. The Coastal Sensitivity Index was developed as part of the Coastal Adaptation to Climate Change...

https://gis.niwa.co.nz/arcgis/rest/services/COAST/Coastal_Sensitivity_Index_CSI_inundation/MapServerService Description: The CSI is mapped as coloured line segments around the New Zealand coast. Each of the 1800 line segments corresponds to a unique combination of geomorphic and oceanographic attributes that reflect that part of the coast’s sensitivity to...
