Physiographic Environments of New Zealand research is developing a cost-effective technique to measure and map (as an integrated physiographic layer) how features of the natural landscape lead to variation in water composition, and hence quality. So far 7 regional and district councils are sharing data and collaborating to develop and apply the physiographic approach to their regions. This document contains information for interested regional councils.
Note: Journal paper validating the use of this physiographic map to direct where to focus mitigation actions in Aotearoa is not yet published.
