Notes:
Non-Darcy groundwater flow parameters are identified for three different flow systems. In the first system, which is essentially one-dimensional, the parameters are determined by means of an integral method. A rectangular parametric grid is used for the identification of the non-Darcy friction coefficients in the second system, which is two-dimensional. The parameters in the third system, which involves a hybrid simulation of three-dimensional flow, are optimized by adopting a constrained non-linear programming technique. This technique combines Cauchy's steepest-descent method together with the modeller's subjective judgement of the results at the end of each iterative step. The paper is concluded with a brief description of the additional research which is thought to be necessary before the difficulties of optimizing the non-Darcy flow parameters can be overcome.
