“…Based on these factors, an expert assessment is formed, which can be obtained using pair analysis (Romanov et al, 2015;Romanov et al, 2020). For this purpose, a matrix of factors is built, according to which the possible vulnerability of sources of non-centralized water supply is estimated.…”

Centralized water supply in remote settlements is often difficult or impossible, so there is a need to use a non-centralized water supply. The article develops a method for an expert assessment of the negative change in the state of underground karst waters based on a paired analysis of complex indicators of the protection of the aquifer. To assess the vulnerability of non-centralized water supply sources, five factors are used, including the geological structure of the territory, the level of surface and underground runoff, the development of the karst network, precipitation regime electrical conductivity, and mineralization of groundwater. The test was performed using the method of inversely weighted distances (IDW). The vulnerability assessment of karst waters was carried out in the area of 10 key control points identified during the deployment of the hydrogeological control system in 2017. Based on various geological and hydrological indicators, the discrepancy between the vulnerability assessment of karst waters was no more than 15 %. The conditions under which it is advisable to use direct measurements or geoelectric methods to monitor karst groundwater's state are identified.

“…When used for groundwater parameter monitoring, geoelectric methods have a number of advantages over other geophysical methods, as the specific conductivity of water-saturated rocks is very different from that of dry rocks [ROMANOV et al 2015]. It is important that the same rock may have different specific conductivity depending on its mode of occurrence, internal structure, temperature, fillup with saltwater.…”

The use of non-centralised water supply in remote settlements is currently the only possible option. Monitoring the water quality of such supply sources is a complicated task in such areas, especially when there are active karst processes and difficult groundwater conditions. The application of deterministic analytical models of water supply under the risk of disturbance to groundwater dynamics is not efficient. Significant quantitative and even qualitative changes in groundwater conditions may take place between the calculated points, and the underestimation of these changes in expectation-driven computation models may result in serious geoecological issues. This research studied and justifies the use of adaptive dynamic hydrogeological control in an area of non-centralised water supply based on the identification of key zones of geodynamic karst monitoring and the electrical express-monitoring of water resources. The identification of key zones is based on an integrated analysis of available groundwater information that describes changes in groundwater hydrodynamic conditions at the time of the karst forecast. The development of karst-suffusion processes is accompanied by more intense dynamic changes in local areas of geologic environment compared to the general variation in intensity. Information about the occurrence of destructive groundwater processes by means of selective geodynamic monitoring may thus be obtained much earlier than with environmental geodynamics monitoring as a whole. The experimental hydrogeological control of an area of non-centralised water supply was conducted on the right bank of the Oka River in Nizhny Novgorod region, a locality with an active manifestation of karst processes. Structure and algorithms of space-time processing of hydrogeological control data developed by authors have been used. The approach based on multifrequency vertical electrical sounding (MFVES) method has shown good correspondence with direct borehole observation when measuring depth of the first aquifer. Zones of unsafe water use have been revealed. The results demonstrated the effectiveness of the proposed method and the need for further regular observations of destructive groundwater processes by means of selective hydrogeodynamic monitoring.

In this paper, an approach to the organization of spatial-temporal processing of geoelectrical data in the system of automated geodynamic control is considered. It allows combining methodical, algorithmic, program and information support of the processes of collecting and processing of geodynamic information at subjects to control. Use of the relations obtained simplifies the geodynamic estimation of the variations of individual isolated research objects on the basis of an analysis of model coefficients in the transfer function of the geoelectrical section.
