Abstract

Saturated hydraulic conductivity is a soil physical property of importance in a wide variety of physical soil and water applications. When the water table is well below the - surface, GUELPH PERMEAMETER method is recommended as the best and most efficient method for its measurement which can be performed quickly by one single person. Two ponding depth analysis of GUELPH PERMEAMETER yield the two unknown parameters Kfs and a* from the sohition of two sets of equations. This method of solution ho ever most often yields a number of negative results which are unrealistic. This is due the nonhomogenuety of semultaneous equations. In this research single head laplace analysis (KL) with zero capillarity, single head of Richards with a*=12 analysis and reagresion single depth analysis of Richards (KR) are used to eliminate negative answer. The results show that the regression analyses of Richards with a single head measurement can yield seliable results. It was also shown that due to a large standard deviation of a* Value, it is preferred to assume its value to be contant.
