Utilization of available experimental data for pollutant transport equation coefficients and source term correction

The equations describing transport of pollutants in an unsaturated water zone depend on a knowledge of a series of data which have their origin in a set of physical and/or chemical branches. The common current procedure represents a comparison of calculational results with those of measurements and, in case significant discrepancies are detected and the disagreement is not accepted, a revision of the theory is necessary and the whole time and effort consuming process has to be repeated. In addition, the question of which part of the calculational procedure has a maximum share in the discrepancy used to be a very difficult one and not unique to be simply answered. There is an alternative procedure described in the paper which is based on a direct incorporation and experimental results into the basic equation and so the correction of its coefficients. There is a principal mathematical algorithm allowing an optimal elaboration of all the data involved in the process (streaming of unsaturated water with pollutants generated in the process of uranium mining in the subsurface layers on the earth crust and during the uranium mine and mill closure) with a condition of the most precise prediction of the future situation presented in the paper.
