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.

In agricultural regions of Western Australia, salinity is spreading. This is because the area taken up by groundwater discharge is increasing as a result of increased groundwater recharge following the replacement of native vegetation systems by annual crops and pasture species. Attempts to reduce groundwater recharge are now being made as it is hoped that this will decrease the rate of land salinisation. At several sites, average recharge rates have been estimated to be from 2% to 13% of the average annu ter hydrographs from the agricultural regions indicate that at some sites recharge does not occur as small amounts …
