Abstract

A method is presented for time variant extent of wetting front and wetting volume that was developed in soil in response to infiltration from surface line source. This method is based on control volume solution of Richard's equation for orthogonal coordination. In control volume method by using implicit scheme, grid size and time of calculated domain can be arbitrarily drawn out. By advantages of simple discretization equation, rapidly performed calculation, direct result of volumetric water content values for various types of soil could be given out. Sand and referenced GILAT sandy loam, PIMA clay were taken to study. Calculated results of vertical infiltration from soil types were verified from referenced paper's result. There's a good agreement between calculated results and the paper's results by using GILAT loamy sand and PIMA clay.
