Abstract

Study of changes in the grounwater regime in space and time on the technologically impaired territory is on the supervisory network of boreholes. This is the first mandatory and the most important part of the hydrogeological monitoring each of the three levels - global, regional and local. Previous studies made by other authors about justify the supervisory structure of the network has an recommender nature, or based on the methods of mathematical statistics. The proposed development has hydrodynamic rationale and based on the theory of mass transfer and filtration. Our additions to rationalisation of the supervisory structure of the regim minimally sufficient number of boreholes from the perspective of the best use of observations for reliable estimate geofiltrational and migration options are : single observational borehole characterize natural or disturbed mode, hydrogeological process at one point of the research area and it is not informative. With two observations in space it is possible to make a straight line, it is enough if hydrogeological process described by Laplace equation. But geofiltrational and migration processes are described by more complex equations of second order in partial derivatives of elliptic and parabolic types. They characterize the nonlinear processes, so the minimum number of observations must be at least three in space and time within each studied object or landscape elements (the flow and across groundwater). There are examples of solving inverse problems of migration and filtration. The hydrodynamic justification of the structure of the regime observations network enhances its scientific value and practical significance. This approach enables maximum accuracy to determine the filtration and migration parameters and solve the forecast problem for the scientific substantiation of a complex of environmental measures. The development of the theory of hydrogeological monitoring is ahead of its implementation, aimed at the result – sustainable use and protection of groundwater and surface water from pollution and depletion.
