The models, methods and algorithms are the basis of system analysis of complex processes of parameters identification of multicomponent bodies with layers to solve important practical engineering problems, environmental ecology, environmental management, assessment of groundwater resources in different regions, the decision of the resource of existing facilities elongation problems, the definition of factors and capacities of groundwater pollution sources, etc. Product Description popup.authors Аралова А.А.
