Abstract: A hydrologic balance model has been developed that employs neutron probe readings for soil moisture content coupled with measured amounts of precipitation and irrigation. The major objective of the model is to estimate ...

Abstract: Four years of weekly soil water data measured by neutron probe were analyzed to determine average daily, monthly, and seasonal drip-irrigated hybrid poplar water use. The plantation studied is located near Boardman, Oregon, ...

Abstract: A simple hydrologic balance model based on neutron‐probe measurements of soil moisture content was used to estimate evapotranspiration for alfalfa. The model results indicated large variations in the amount of estimated ...

Abstract: The Su-Brooks retention function was linearized by transforming the functon into logarithmic form. The resulting equation had a form that allows determination of the parameters using linear multiple regression techniques. ...

Abstract: The Penman method using hourly and daily weather data was evaluated to estimate daily reference evapotranspiration over a well-established stand of Alta fescue under different atmospheric conditions. The performance of the ...

Abstract: Estimation of evapotranspiration is a key requirement of hydrologic balance studies and climate analysis. The study reported involved collection of precise weighing lysimeter and meteorological data from three sites ...
