资源简介：
This entity describes the impact of Urbanisation on the River Environment by calculating the Velocity Heterogeneity (longitudinal) Impact factor. Heterogeneity of substrate and in-stream habitat is incredibly important for aquatic fauna, with variety providing diverse options for refuge, feeding and breeding habitat. It is derived from surveyed Water Volume data using raster GIS. Variability of velocity under 20% is considered (Urban) impacted. It is spatially abstracted to a line. Entity type: Concept.
