The scaling constant \theta _n is an unimportant technicality, which just permits some useful estimates, and is chosen so that the graph of w_n always lies inside the “multi-graph” of w_n (x_i) \pm \theta _i |g_i|, for all 0 \le i \le n; see (3.3) below for a precise...
A semi-continuum model for fluid flow in saturated-unsaturated porous medium in one spatial dimension is presented. The model is based on well-established physics, measurable parameters and material characteristics. The porous material is characterized b
