Seepage through Layered Anisotropic Porous Media

The paper summarizes an investigation of seepage from leveed rivers into low-lying adjoining agricultural lands. Only the flow rate and distribution of seepage as a function of the surface and subsurface boundary conditions were studied. Flow nets in idealize d cross sections were determined by an electric analogy model. Boundaries represented channel bed and bank, a levee base, a lower impermeable stratum, and the water table in adjoining drained agricultural land. Variables studied included two subsurface layers of different permeabilities and anisotropies, layer arrangements and thicknesses, channel depth and width, levee base width, and water table slope.
