Abstract

With recharge to ground water problems and also lack of ground water resources, in this paper see page discharge and subsurface were modeled for fine-grain soil with Surface recharge by a Laboratory model. It was compared the results of experimental with the results of Bear (1972) and Castro-Orgaz et al (2012) analytical solutions. Laboratory model having fine porous media has 5 m long, 0. 6 m wide and 1 m deep. For different water levels and bed slope of 0. 0135, the seepage flow and subsurface water profile were measured under Surface recharge condition and then were compared with the above-mentioned analytical solutions. Comparison seepage flow were compared with experimental seepage flows and the value of relative error were determined. Also the different between experimental and analytical results were determined means of NOF. After the comparison between experimental and analytical results, the weakness and strength of each method has been revealed. After comparison and evaluation the results of the discharge experimental with the analytical relationship Bear (1972) the relative error was between 4. 2 to 6. 4 percent, and then were compared with analytical relationship. The values of relative error percent and NOF function for compared and measured variables were computed. After comparison of experimental results and analytical solutions, the weakness and strength of each method has been revealed. After comparing the results of the discharge experimental with the analytical relationship based on Dupuit-Forchheimer assumption the relative error was between 4. 2 to 6. 4 percent. By the comparison of the experimental results with analytical solution for Subsurface flow profile, the NOF were analytical between 0. 012 to 0. 048 for Chapman, 0. 011 to 0. 081 for Bear and 0. 011 to 0. 078 for Castro-Orgaz et al, respectively, which indicated a proper confirmation.
