Seepage from Canals with Infiltration from Free Surface Zone
Publication: Journal of Irrigation and Drainage Engineering
Volume 123, Issue 4
Abstract
An analytical solution is obtained for estimation of seepage from a canal to symmetrically placed drainages founded on infinite pervious soil medium with uniform infiltration from the free surface zone. Integral equations are obtained by using Zhukovsky's function, a special function, and the Schwarz-Christoffel transformation. These equations are then solved numerically to obtain the value of seepage loss and profile of the free surface. Results are obtained for different values of parameters such as canal width, the distance between the canal and drainages, depth of drainages below canal level, infiltration rate, etc.; and the same are presented in the form of graphs, showing the effect of these parameters on the seepage discharge and the free surface profile. Nomographs are also prepared for easy evaluation of canal seepage discharge.
