Abstract : The computer programs for levee underseepage analyses-LEVEEMSU (finite difference), LEVSEEP (closed form), and SEEP (finite element)-were used to analyze a levee and foundation section described in this report. Results presented in this study illustrate the effect of variations in the ratio of permeability of the foundation %) to the permeability of the blanket (I%) on the flow predictions, the influence of introducing anisotropic conditions on flow domain, arid variation in the predicted hydraulic gradients in relation to the analysis method. Analysis results are reported in terms of landside exit hydraulic gradients and permeability ratios.
