Theory of Some Free Surface Groundwater Seepage Problems
Analytical methods were developed for steady-state unconfined flow to determine the exact location of the free surface in: (1) A two-dimensional flow of groundwater between two parallel ditches; (2) a two-dimensional flow in a groundwater mound formed by water infiltrating from a rectangular recharge basin; and (3) a three-dimensional axisymetric flow in a mound formed by infiltration from a circular recharge basin. Flow in a saturated region below the watertable was considered capillary but effects were neglected. It was shown how the analysis of a two-dimensional flow could be carried over to determine the location of the free surface in a three-dimensional axisymmetric flow toward a well. Solutions were obtained from potential theory by solving Laplace's equation, and to satisfy an appropriate set of boundary conditions a modified Gram-Schmidt technique and a simple iterative scheme were used.
