SOLUTIONS FOR UNCONFINED NON-DARCY SEEPAGE

Numerical and experimental studies of non-Darcy flow in porous media are examined. Laboratory experiments using a sector and two-dimensional flow through a bank with vertical sides in a flume. Parmeameter tests on the gravel were used to estimate coefficients in the nonlinear relation relation between head loss and velocity. Results are presented of analyses performed using a finite difference solution of the appropriate partial differential equation boundary value problem. The flow nets and discharges obtained are compared with the experimental results and the corresponding solutions for Darcy flow.
