Description: The River Environment Classification (REC) is a database of catchment spatial attributes, summarised for every segment in New Zealand's network of rivers. The attributes were compiled for the purposes of river classification. Examples where the REC can be used include, catchment rainfall calculations, catchment river flows, flood forecasting, land use and catchment associations.
Creation
the REC was originally created using a hydrological networking tools and a digital elevation model.
NIWA acknowledges funding from the MBIE SSIF towards the preparation of REC v2.5
