MBC Zones of potential hydrological change

Abstract

This dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This is a set of polygon feature classes representing the boundaries of zones of potential hydrological change in the regional watertable, and groundwater model layers 10 and 12. These boundaries were created mainly for cartographic purposes enabling the outline of zones to be shown.

Dataset History

Polygons were derived by overlaying the 95th percentile additional groundwater drawdown values (for the regional watertable, and layers 10 and 12) to the MBC assessment units, selecting values >=0.2m and dissolving the result to give a single polygon shape representing the area where the 95th percentile additional drawdown was >= 0.2m (i.e. the zone of potential hydrological change) for each layer (regional watertable, and modelled aquifer layers 10 and 12).
