| Filtration deformations are considered under conditions of significant decreasing infiltration rate I based on an exact analytical solution to one-dimensionel unsteady problem of joint groundwater and mass transfer within suffosion soil. Regularities of mobile unstructural particles fallout and colmatage layer formation are analyzed. The cases of uniform and nonuniform changing rate I are under study at various initial particle contents. Limits of field of mathematical model application are established and ways of its developing are discussed. An estimation are performed for reducing soil permeability due to redistribution and fallout of mobile particles. |
