Abstract

The study presents the results of vertical infiltration on saturated clay of three different particle of sizes 0.01, 0.001 and 0.002 mm under different hydraulic gradients. A range of hydraulic gradients were achieved by varying the clay length, L in respect to head, h in the permeameter. The aim of the study is to establish a model to determine the saturated hydraulic conductivity vis-à-vis permeability of soils as a function of time, for accurate estimate of volume of water available for plant growth in surface irrigation. The equations obtained show that permeability \( K - t \) curves show that the declination of permeability will never be zero, except at an initial state or stage before the commencement of infiltration process. This equation from the hydraulic conductivity – time (K – t) curve is simple and practically useful for the determination of permeability at a particular time.
