Abstract

The South Coast Regional Initiative Planning Team (SCRIPT) has divided the South Coast region into six sub-regions. The Fitzgerald Biosphere sub-region is located in the centre of the South Coast region of Western Australia (Figure 1). It is bounded by the Pallinup River to the east, Jerdacuttup River to the west, and includes the catchments of the Gairdner, Fitzgerald and Phillips Rivers. The sub-region encompasses the Fitzgerald Biosphere Reserve and just over half (730,000 ha) has been cleared for agriculture.

This publication describes the groundwater trends, risk of shallow watertables, and technical feasibility of salinity management in the soil landscape zones within the agricultural land.

Soil-landscape zones are spatial units based on geology and geomorphology. As_ most groundwater processes in WA are controlled by the geological and regolith properties, typical landscape profiles within these zones can be used for allocating hydrological attributes, such as groundwater characteristics and trends. The hydrological attributes are then used to assess the risk of shallow watertables and technical feasibility of salinity management.

Refer to Further Information for a description of groundwater flow systems, risk analysis and technical feasibility of salinity management.
