Catchment Salinity : Report On A Study Of The East Perenjori Catchment, C J. Henschke

Resource management technical reports

Dryland secondary salinisation has debilitated large areas of land in Western Australia due to clearing of native vegetation for agricultural development. The initial aim of the project (which is the subject of Part I of this report) was to establish a landscape framework for hydrogeological examination of the salinity problem. A catchment of 139 km2, located 30 km east of Perenjori townsite was selected for detailed study. It was mapped for soils, vegetation, topography, landform and salinity using both old and recent aerial photography. A field survey of soil hydraulic conductivity was undertaken to help define recharge areas. Soil-vegetation associations …
