I'm developing a groundwater flow model in feflow and when I assigned vertical hydraulic conductivity as 0.1 times of Kx my model becomes too slow. i have given pumping wells at various depth and the area consist of both sedimentary and weather hard rock formation with one boundary as coastal region. I assume that when vertical conductivity is low, some pumping wells get dry since recharged water is not reaching at bottom of aquifer due to low vertical conductivity. Is it possible to assign Kx,y,z as same conductivity?. looking for some suggestions and help. Thank you
