The Suspended-Sediment Yield Estimator was used to estimate the suspended-sediment yields from New Zealand’s rivers and streams. Predicting long-term average suspended-sediment loads in rivers and streams is useful for dealing with a variety of issues. These include sediment entrapment rates in potential reservoirs and the vulnerability of estuarine and coastal marine habitats to sediment influxes from the land.

    SSYE uses a raster-based GIS layer of specific suspended-sediment yield (SSY, t/km2/y) from New Zealand’s rivers and streams has been generated based on gauged sediment yields at over 200 river stations and an empirical model.
