Potential Runoff Accumulation In Wheatbelt Towns Of Western Australia, Mahtab Ali, Travis Cattlin, Neil Coles, Sharam Sharafi Dec 2001

Potential Runoff Accumulation In Wheatbelt Towns Of Western Australia, Mahtab Ali, Travis Cattlin, Neil Coles, Sharam Sharafi

Resource management technical reports

Describes an analysis of flood runoff volumes from 16 small, gauged catchments in the agricultural areas of south western Australia. It also describes methods for estimating flood runoff volumes from ungauged catchments. The independent variables found to be statistically significant in explaining the variability in flood runoff volumes from the gauged catchments were catchment area, mean annual rainfall and the percentage of the catchment that was cleared. No soil factor was found to be significant.

Calibration And Use Of A Combination Atmometer To Estimate Evapotranspiration And Monitor Soil Moisture Storage On Farmland Catchments In Western Australia, K J. Bligh Apr 2001

Calibration And Use Of A Combination Atmometer To Estimate Evapotranspiration And Monitor Soil Moisture Storage On Farmland Catchments In Western Australia, K J. Bligh

Resource management technical reports

The readily-operated combination method of estimating evapotranspiration was applied using simple atmometers, calibrated against absolute evapotranspiration. While 76.6 per cent of the variance of estimates was accounted for by the regression in the first season under wheat, no significant results were achieved in a further four seasons. Combined data for two seasons under legume pastures enabled 30.1 per cent of the variance of estimates to be accounted for.

Extent And Impacts Of Dryland Salinity, C E. Mcconnell, R Short Jan 2001

Extent And Impacts Of Dryland Salinity, C E. Mcconnell, R Short

Resource management technical reports

The extent and impact of dryland salinity in Western Australia was based on analysis of groundwater depth and trend and the risk of shallow watertables is derived from these two attributes. As dryland salinity is caused by shallow watertables, the risk of salinity is inferred from the risk of shallow watertables.
