In article the structure of an informational-hardware support of the automated system of data processing at electromagnetic monitoring of geodynamic objects is considered. The structure of interrelations of the object-oriented and serving subsystems realizing methodological, program and technical and information support of processes of filing and data processing of geodynamic monitoring is defined. It is noted that increase of geodynamic sensitivity due to selection of the abnormal components of signals and obligation of monitoring of variations of separate geodynamic objects in the studied environment results in need of expansion of informational saturation and a variety of geoelectric models. In this case the applied algorithms of informational processing can be focused only on the analysis of the abnormal signals, and the geodynamic assessment will be defined by structure of the models of geodynamic objects used at interpretation. It is defined that the problem of prediction of geodynamic processes can be solved on the basis of expected model operation.

The article discusses the algorithm for assessing changes in the level of risk of karst hazard of the territory based on the forecasting of the number of holes depending on the water level. Based on the results of the analysis, the values of bifurcation parameters are determined, the transition through which sharply increases the formation of new holes. The article provides the developed block diagram of the neural network for assessing the dynamics of the occurrence of holes, as well as an algorithm for generating a predictive estimate of the number of holes. An analysis of the occurrence of the number of holes is carried out on the basis of water level data in the Oka River. The results of spline interpolation of the data are presented in the dependence on the number of holes on the dynamics of the water level in the river for the current and previous year. Practical verification of the developed algorithm was carried out on the basis of the new set of data on the water level in the river and the number of holes. The developed algorithm can be used in predicting the spread (leaching from the soil) of pollutants.

In this article, techniques and algorithms of the control and forecasting of the karst risk of the territory are considered. The formation of forecast assessments of the development of suffosion processes is carried out on the basis of the computer modeling with the correction of model data on the flexible schedule by results of the monitoring. To reduce the costs of the monitoring work, the resistive control method is proposed to use. This method is based on the phasometric principle of the control of the development of suffosion processes. In the article causes and stages of the development of suffosion processes are gives, features of the development and the control of suffusion processes are described for urban territories. The modeling of suffosion processes is carried out on the basis of the geoelectrical model of the spherical cavity of the covered thickness of soil sediments. The description of the experimental setup is given for the modeling of the suffosion processes and for the control of their formation by the phase control method. The estimation of the adequacy of results is obtained. The approbation of the proposed algorithm was carried out at the site of the alleged development of man-made suffusion processes. The identification and localization of the suffosion processes took place on the basis of the risk map and the phaseometric control method. The correction of the model was carried out by the data of the georadar survey of the investigated area. The proposed algorithm allows minimizing the costs of monitoring activities and increases the accuracy of forecast estimates during the modeling the geological environment on simple models.
The paper substantiates the application of the phase control of the multipolar equipotential electrical installation to improve the geodynamic sensitivity of the geoelectric control method in geodynamic and geotechnical monitoring systems. The principle of the control of the source of sounding signals and the detection of geodynamics of the geological environment is shown in article. In this work is proposed the device on base of the phase modulator to eliminate the shortcomings of existing devices of the controlling of the phase of sound geoelectrical signals. The developed device contains two amplitude limiters, the integrating unit, the adder, the master oscillator and the amplitude modulator. In practice the application of the proposed device allow to obtain the technical and the economic efficiency by simplifying of the circuit of the generation of the signal with the phase-modulation, by increasing the linearity of the modulation characteristic, and by generating of the signal with the phase-modulate on output of the device.
