| Abstract |
Studies were made to determine how water moves in unsaturated soils under non-isothermal conditions produced during evaporation for three situations: (a) one- and two-dimensional flow in homogeneous soils; (b) two-dimensional flow in soils with simulated shrinkage cracks; and (c) one- and two-dimensional flow in layered soils. Differential equations describing simultaneous flow of heat and moisture are solved for the boundary conditions given. Experimental and theoretical results are compared to test the validity of the differential equations of Philip and deVries that describe simultaneous heat and moisture flow. (Author) |
