Determine the solution in the expansion fan. In this problem, we consider the flow of water through a porous medium. Specifically, u, is the water content at depth z and timet measured as a ratio of water-filled pore space to total pore-space. (Thus, 0 u 1.) We assume that u satisfies the conservation law and initial condition (12), + ut = 0 t>0 x<0 a(x, 0) = 0 u(r,0)-0 > In this problem, we consider the flow of water through...
