It is proposed that a numerical environmental model cannot be justified for predictive tasks without an implicit uncertainty analysis which uses reliable and transparent methods. Various methods of un...
AN ESTIMATION OF EVAPOTRANSPIRATION BY MEANS OF THE WATER BALANCE OF A SOIL COLUMN
ESTIMATION OF EVAPOTRANSPIRATION MEANS OF THE WATER BALANCE SOIL COLUMN
2009/10/30
In this paper water-balance studies of a soil column at an observation site
at Ulvsunda, Stockholm, are reported. The change of the water storage in
the soil was obtained from soil moisture measurem...
