Dryland Catchment

The site chosen for the preliminary dryland study was Gerangamete located south-western Victoria. This dryland catchment covers 200 ha with an average annual rainfall of approximately 770mm. The catchment is characterised by low permeability duplex soils. Sheep and cattle grazing are the dominant land uses and saline discharge commonly occurs at the break of slope.

The model domain incorporates The Centre for Land Protection Research sub-catchment of the Agro-forestry site and was extended to encompass the larger catchment, bounded by the West and East branch
