Analytic and numerical solutions of variable boundary seepage model of the unstable well flow in underground water flow;

WT5”BZ]By using coordinate transformation of revolve, compression and again revolve, this paper deduces an analytical solution for 3 D unsteady well flow in leaky aquifers, which is the extension of Theis solution, Hantush solution and the solution given by way for unsteady well flow in radically anistropic aquifers.

A universal solution to unstable groundwater movement in vicinity of canals;
