Abstract
This article shows that the most sensitive indicator of local and regional karst activity in territories of apparent karst processes is the behaviour of karst lakes. The authors propose a hydrogeological monitoring methodology for the karst process based on the phase-measuring geoelectric control method in the coastal zone of karst lakes. The geoelectric current control of hydrogeological changes in the medium at local levels uses a multi-frequency vertical electric sounding combined with a phase-measuring method of registering the geoelectric signal. These proven methods permit to distinguish variations of spatial parameters and the electric conductivity of several layers at a time. Moreover, they significantly increase the noise resistance and sensitivity of the measuring system. An adaptive algorithm function of the measuring complex for geoelectric monitoring of karst lakes’ coastal zones was developed to control the operation of facilities and data collection systems. Based on an example of a lake where karst processes are active, the key zones of hydrogeological control were identified depending on karst manifestations. The research confirmed the possibility of local and regional monitoring of the development and forecasting of destructive karst-suffosion processes based on hydrogeological regime observations of karst lakes.
期刊介绍:
Journal of Water and Land Development - is a peer reviewed research journal published in English. Journal has been published continually since 1998. From 2013, the journal is published quarterly in the spring, summer, autumn, and winter. In 2011 and 2012 the journal was published twice a year, and between 1998 and 2010 it was published as a yearbook. . Papers may report the results of experiments, theoretical analyses, design of machines and mechanization systems, processes or processing methods, new materials, new measurements methods or new ideas in information technology. Topics: engineering and development of the agricultural environment, water managment in rural areas and protection of water resources, natural and economic functions of grassland.
