Nonlinear Steady State Seepage into Drains
Publication: Journal of Irrigation and Drainage Engineering
Volume 115, Issue 3
Abstract
Analytical solutions for water table profiles between drains and drain spacing formulas resulting from nonlinear seepage under steady rainfall recharge are presented. Nonlinear seepage conditions are introduced in the derivation of the equations, which are found to be generalizations of those conventionally used on the basis of Darcy's linear law. The validity of the equations derived was established in a series of experiments on a sand tank seepage flow model in which nonlinear flow conditions were generated, giving rise to actual water‐table profiles. The equations derived herein were found to show close agreements with experimental results and with similar studies reported by some authors, and to provide for greater economy in the design of drainage systems.
