Seepage to the drain below a thin, low permeable alluvial layer
Summary.

The paper is concerned with two-dimensional, steady seepage to a drain located below the thin, alluvial, low permeable layer deposited at the bottom of a reservoir. Thin layer was excluded from the flow area and modelled using the third kind boundary condition, as a linear relationship between the sought piezometric head and flow through the top border. The author’s software, based on finite elements method, was used to obtain solutions. The results were consistent with the available analytical solution (one drain in the boundless strata with homogeneous and isotropic seepage properties). Different variants of the position of the drainage gallery under bottom of the reservoir, the effect of the stratum thickness and orthotropy seepage conditions were discussed in detail. The solution for the system of parallel drain gallery was also analysed.

Key words: seepage, thin layer, drainage, third kind boundary condition
