Observations On Groundwater Recharge In The Westdale Catchment, M F. Lewis, C E. Mcconnell Dec 1998

Observations On Groundwater Recharge In The Westdale Catchment, M F. Lewis, C E. Mcconnell

Resource management technical reports

A study of the role of groundwater carriers and barriers in controlling salinity was carried out in the Westdale Catchment by Lewis and McConnell (in preparation). Although that study was primarily concerned with groundwater flow and discharge processes, the data collected also provided rudimentary information on the timing of groundwater recharge events and their distribution across the landscape.

Resource management technical reports

High water use vegetation systems for salinity control were trialed on a 170 ha catchment located 13 km north of Kojonup, Western Australia. The catchment receives about 470 mm annual rainfall and 1825 mm annual evaporation.

Resource management technical reports

High water use vegetation systems for salinity control were trialed on a 90 ha catchment located 12 km north north-west of Darkan, Western Australia. The catchment receives about 560 mm annual rainfall and 1895 mm annual evaporation. The catchment is characterised by a number of actively expanding seeps which are developing under the strong geological control of quartz and dolerite dykes. Development of salinity is also influenced by high recharge rates in the free draining gravel soils of the upper slope.

Resource management technical reports

High water use vegetation systems for salinity control were trialed on a 250 ha catchment located three km north-west of Dinninup, Western Australia. The catchment receives about 620 mm annual rainfall and 1500 mm annual evaporation. The catchment is characterised by slopes with gradients in excess of 5%, deep weathering (15-25 m to bedrock), active seepage in the valley (piezometric heads 204 m above ground surface) and high recharge (water table fluctuations of 1-4 m).

Resource management technical reports

High water use vegetation systems for salinity control were trialed on an 80 ha catchment located 12 km east of Frankland, Western Australia. The catchment receives about 510 mm annual rainfall and 1525 mm annual evaporation. Development of salinity in the catchment is concentrated in the valley floor. Here the groundwater is extremely saline (3000-4000 mS/m) and piezometric levels are between 1 m below and 1 m above the surface.

The south-western Woolbelt receives annual rainfall between 500-700 mm with long dry summers and cool wet winters. The dominant land use is grazing of Merino sheep for wool productiion, with smaller areas (5-15%) of cropping. All of the catchments selected were affected by salinity, but the extent and severity varied. In all catchments the location of the major expression of salinity was the valley floor.

Resource management technical reports

High water use vegetation systems for salinity control were trialed on a 70 ha catchment located about 15 km north of Williams, Western Australia. The catchment receives about 545 mm annual rainfall and 1870 mm annual evaporation. Development of salinity is characterised by passive discharge upslope from a dolerite dyke. Because recharge exceeds the discharge capacity of current seeps, there is potential for new seeps to develop in the mid to lower slopes.
