Ditch Drainage in Layered Soils
Publication: Journal of Irrigation and Drainage Engineering
Volume 117, Issue 2
Abstract
The assumption of considering the lower layer to be impervious, if its hydraulic conductivity is one‐fifth or less from that of the upper layer, leads to erroneous results. Many research workers have attempted solutions to the problem of subsurface drainage in layered soils with different boundary conditions. An alternate, simple, and explicit solution based on Girinsiky's potential has been proposed in this paper. Experimental data observed on a vertical Hele‐Shaw model have been used to verify the analytic results.
