ABSTRACT
In cases of interconnection of a few water layers, in the adherence of criterion filtration is related to planospatial during which in highly permeable layers it is planar and in the dividing weakly permeable interbeds, vertical. In 1960, the theoretical basis of the method was developed and it is now known as the method of filtration resistances. Calculations of interacting generalised systems can be carried out as for discrete wells by the method of superposition and the influence of the boundaries is computed by the method of mirror reflections. The influence of external boundaries of the layer and the interaction of the wells are considered the same as for an isotropic layer. While satisfying criterion the two-layer formation is represented by a calculation scheme in which the upper loamy layer contains unconfined groundwaters and the lower sandy layer contains confined or artesian waters.
