Theoretical Study of the Effect of Permeability Tensor upon Drainage of Soils

the influence of permeability tensor upon drainage anisotropic soils under ponded water and steady recharge (rainfall) is theoretically investigated. Tensorial has led to formulation mixed type partial differential equations. Since there no analytical solution this problem, therefore solved numerically by method finite elements. The element implemented into a computer model which can be applied any problem seepage state conditions. Two different example problems representing two flow conditions full anisotropy have been studied. Results for isotropic case were checked against exact mathematical solutions derived analytically found accurate indicates that using safe sound
