This layer depicts estimated sediment/soil loss across New Zealand and was created using the NZeem erosion model. Erosion control is defined as the prevention of soil loss by an ecosystem. NZeem has been calibrated from sediment discharges measured in New Zealand rivers (Dymond et al., 2010). This model estimates the long-term mean erosion rate from all...

Mean annual erosion rates (tonnes of soil/km2/yr) in the South Island of New Zealand under current landcover generated from EcoSat Woody (2001-2003). This layer is not available for download on LRIS. If you are interested in downloading that layer, please contact John Dymond. Reference: John R. Dymond, Harley D. Betts, Christina S. Schierlitz, An erosion...

The NZLRI is a spatial database containing about 100,000 polygons (map units), each of which describes a parcel of land in terms of five characteristics or attributes (rock, soil, slope, erosion, vegetation). This layer represents a GIS dissolve on the erosion attribute of the NZLRI.

Wellington City Corrosion Zone as determined by NZS 3604:2011. Corrosion Zones relate to the severity of exposure to wind-driven salt, with B being low risk, C medium risk and D high risk (Category A is not applicable in New Zealand). The Wellington City territory authority area is located in zone C aside from the coastal zone. For this reason the coastal...

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 Marine Environment Classification (MEC), a GIS-based environmental classification of the marine environment of the New Zealand region, is an ecosystem-based spatial framework designed for marine management purposes. Developed by NIWA with support from the Ministry for the Environment (MfE), Department of Conservation and Ministry of Fisheries, and...

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_erosion/MapServer/ The Coastal Sensitivity Index was developed as part of the Coastal Adaptation to Climate Change (CACC) project. This four-year project funded by the Ministry of Business, Innovation & Employment (MBIE contract C0X0802) was intended to create the...
