A one-dimensional model of unconfined ground water flow over a sloping impermeable base [electronic resource] / A. Vandenberg. Ottawa : National Hydrology Research Institute, Inland Waters Directorate, 1982. v, 30 p. : chart, ill. NHRI paper ; no. 17 IWD technical bulletin ; no. 125 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "A mathematical one-dimensional model of unconfined ground water flow over a sloping impermeable base is described. The model employs a Crank-Nicholson implicit finite-difference formulation, in which the non-linearity of the differential equation owing to the varying saturated thickness is handled by iterative adjustment during each time step. Five examples of possible applications are described, and the model results are compared with analytical solutions"--Abstract, p. v. Includes abstract in French.
