Currently, special attention is paid to the existing ecosystem of urban development, special attention deserve wherein resort towns. There is a number of environmental concerns of the KMW region attractive for its natural-resource data, one of which is the noise pollution of the urban environment. The main source of this pollution for the city with the nonproductive functional orientation is transport infrastructure. Formation of cities in the region, which began in the XIX century, did not provide for traffic congestion and power sources of the modern city, so today it is necessary to analyze the noise loads and, if necessary, to organize the work to restore an enabling environment resort towns of the KMW region.

North Caucasian Federal District as a whole and especially-guarded resort region of Caucasian Mineral Waters in particular, belongs to the territories which attract attention from an environmental point of view. Despite the attractiveness of the region CMW(Caucasian Mineral Waters )there exist a number of environmental problems that require serious scientific study and making certain decisions. In this paper, there is an analysis of the current radiation situation in the region of CMW(Caucasian Mineral Waters) and there are outlines of conducted scientific research which have the following main task: determination of regularities of formation of the radiation situation in the objects of environment, building and urban economy of the region; determination of levels of irradiation of the population of the region in different conditions and from different sources; the working-out of specific measures to comply with the radiation safety standards.

A modified analog-SSOR of variation type is used for numerical realization of two-dimensional discrete mathematical model of the aquatic environment, which is based on a three-dimensional hydrostatic model. Governing equations of the given model are equations for incompressible fluid, hydrostatic equation and Navier-Stokes equation. Developed model is used to predict the processes of sedimentation and the impact of negative factors affecting the condition of coastal and offshore structures. An algorithm for the minimal residuals modified analog-SSOR method for solving the difference equations is presented in the paper. The results of numerical experiments are presented.
