Seepage Around Horizontal Drains in Hill Slopes
Publication: Journal of Hydraulic Engineering
Volume 109, Issue 10
Abstract
An empirical equation is derived for horizontal drains. The equation is based on results of finite element analysis and verified by a set of laboratory experiments. The empirical equation provides a simple and quick way to calculate the downstream water depth as a function of the drain spacing and slope of the impermeable bed. The equation is useful for planning or design, purposes, or both, when horizontal drains are used for lowering the groundwater table in slopes.
