THE INFILTRATION PROBLEM WITH 'LARGE CONSTANT SURFACE FLUX IN PARTIALLY SATURATED POROUS MEDIA"
A LiAsJu · 2005
Infiltration problem with two kinds of degenerate cases is consid~ed. After proving existence o~' weak solution, we study when water content e (u ( . , t)) has compact support and how the solution behaves as t--~oo. Moreover, we get existence and regularity of two kinds of free boundaries under some conditions on the initial date. and assume l = J : . . becomes w
