Abstract
Unsteady vertical flow of water in unsaturated soils was simulated utilizing S/360 CSMP (Continuous System Modeling Program), a recently developed language specially designed for digital simulation of transient phenomena that can be represented by differential equations. Two computer programs were developed. One simulated vertical unsteady infiltration through the surface into a homogeneous unsaturated soil. The other computer model simulated unsteady vertical flow of water in an unsaturated homogeneous soil during infiltration from a buried source and through the drying period. (Author)
