Analytical and Computer Solutions of Transient Water Tables for Drainage of Sloping Land

Abstract

Transient water table drawdown in sloping land lying between parallel open ditches was obtained by solving Boussinesq's equation on the analog computer and by analytical methods for zero and time‐variable end conditions at the ditches. Comparison of the results with observations made on a viscous flow model indicated that the solution with time‐variable end conditions described the flow region beter than the solution with zero end conditions.
