A theoretical investigation is performed of water infiltration into two-fraction soil composed of particles of two sorts - structural and unstructural. A mathematical problem is developed of joint ground water flow and solid particles transport during wetting dry soil on the basis of the Green-Ampt model. An exact solution to the problem is obtained. The intensity of water inflow is considered to be known. Two approximation expressions (polinomial and exponential) are used for the intensity mentioned. A thorough analysis is conducted of unstructural particles re-distribution within the accumulation zone when inflow inoreasing. An influence of soil mechanical properties (initial content, averaged size of particles) on soil permeability is closely studied.
