Physiographic science works ‘backwards’, using water composition to trace the water’s journey back through the landscape to understand the landscape controls over water composition, and hence quality.
Physiographic Environments of New Zealand (PENZ) researchers are using national and regional water composition and quality data sets, in conjunction with existing geospatial layers, to map and numerically model the processes that control the spatial variability of water. The method brings together data for climate, topography, geology, soils, and hydrological controls with analytical chemistry at a national scale.
