by H.Y. Hammad,

Serial Information: Journal of the Irrigation and Drainage Division, 1962, Vol. 88, Issue 1, Pg. 15-36

Document Type: Journal Paper


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.
