Abstract:

Paper discusses saturation of agricultural soil by over-irrigation or rain; downward seepage flow through porous soil to system of parallel tile drains is studied, and theory of hydrodynamics is developed for providing scientific basis for design; new spacing formula is obtained based on time variation of water table; effect of evaporation from soil surface on spacing formula.
