Popis: Within the framework of fractional-differential mathematical model, the formulation of boundary-value problems of convective diffusion of soluble substances with regard to immobilization under the conditions of stationary profile filtration of groundwater from reservoir to drainage is performed. In case of averaging the filtration rate over the complex potential region, closed solutions of boundary-value problems, corresponding to classical and nonlocal boundary conditions are obtained. In the general case of the variable filtration velocity, a technique is developed for the numerical solution to the boundary-value problem of convective diffusion in a fractional-differential formulation, the problems of parallelizing computations are covered, and the results of the computer experiments are presented.
