On the basis of engineering and design surveys of the building, engineering-geological and geophysical studies of the soils of the territory conducted by the article authors, as well as with due regard for the results of studies conducted on this territory by other authors, the features of the foundations, soils of their foundation and engineering-geological conditions of the territory of the Melnikov House are established. It is shown that the Melnikov house is located under complex engineering-geological conditions on the territory of high geological risk, in the zone of influence of tectonic disturbance. To the North of the area there is a zone of intersection of the observed disturbance with a larger disturbance that can have an impact on geological processes. To the North-East of the site of the Melnikov House, a sharp immersion of the roof of carbon deposits was revealed. It promotes groundwater seepage into limestone of the carbonate strata from overlying water-bearing sands and activation of processes of suffusion removal and sinkhole phenomena of the soil. The surveyed area is assessed as potentially karst-hazardous and adjacent to it from the North-East territory as karst-dangerous. In this regard any construction on the adjacent territory can provoke activation of sinkhole phenomena on the surface. The foundations of the building are basically in working condition. Existing defects can be eliminated during repair. The foundation soils mainly have sufficient bearing capacity. Areas of the base with bulk soil can be reinforced. However, when developing a project for the reconstruction of the building and its territory, it should be taken into account that the design of the Melnikov House does not provide for its operation on the loads at the formation of sinkholes.

The purpose of the work is to consider methods for calculating the forecast of groundwater backwater in the zone of influence of hydraulic structures. The analysis of analytical dependences of calculation of the forecast of groundwater backwater for various calculation schemes is carried out. For a homogeneous scheme of the geofiltration structure, a numerical model is proposed and a computational program for calculating the groundwater backwater is developed. It allows calculating the groundwater backwater from the channel at any time in the discrete mode. To simplify the solution of the problem of calculating the groundwater backwater, a computer program was created in the programming language Phyton Version 8.3 which quickly solves this hydrogeological problem. A possible range of geofiltration parameters is proposed for calculating the groundwater backwater near main channels. The adaptation and implementation of the software model was carried out for a specific object – the Bolshoy Stavropol channel-5, for which forecast calculations were made. The results of predictive calculations of groundwater backwater are the basis for the assessment of areas of possible flooding – the territory within which the level of ground water increases as a result of their backup by a hydraulic structure.

Introduction. Sanitary legislation of the Russian Federation provides for the organization of sanitary protection zones of industrial enterprises located in the industrial hub. However, the justification procedure, establishing and monitoring boundaries of a single sanitary zones not fully resolved. This determines the practice of organization by economic entities of individual zones separating production from residential development. This situation complicates the adequate assessment of real pollution, as well as the reasonable development of programs (plans) of environmental measures. Identification of the sources that create poor air quality and public health risks is becoming extremely problematic.The aim of the study is to develop and test recommendations for the organization and methodological support of the design of a single sanitary protection zone of a group of enterprises in the current urban development.Materials and methods. The object of the study is an industrial hub formed by 5 industrial enterprises and located on the territory of a large urban settlement with a population of more than 450 thousand people. The city administration carried out a number of organizational measures that ensured the simultaneous inventory of emissions of enterprises and the design of the general sanitary zone of the industrial complex. The design work was carried out in full accordance with the current regulatory framework.Results. The verified unified database of 102 sources of chemical emissions and 113 sources of noise provided the possibility of summary calculations and obtaining the most correct results for surface concentrations in the zone of influence of the industrial hub. The program of quality control of atmospheric air defining the contribution of each economic subject to carrying out researches is formed. This made it possible to ensure the control of all priority contaminants at the outer border of the sanitary zone and reduce the costs of each separate economic entity. Zones of responsibility of each enterprise within borders of a uniform sanitary zone for tasks of maintenance of the standard maintenance of the territory are allocated.Conclusions. The obtained results confirmed the feasibility of designing unified sanitary protection zones for economic entities located in the industrial hub.
