Abstract
The subject of our research was to study the current state of the Tsageri catchment, using georadiolocation and ultrasound methods. Georadar Zond 12e was used in the research.. Georadar data were collected and processed with Prizm 2.7 regular Software. With the help of georadar, it is possible to highlight voids, cracks and weakened environment. It is also possible to determine the degree of humidity of the environment. Antennas of different frequencies are used to study different environment. By our research was used 1 MHz, 1.5 MHz and other frequencies antennas. Ultrasonic method is also an effective tool for determining the mechanical parameters of the environment and itsl structure. In the presented works, the ultrasonic equipment manufactured by the Swiss company PROCEQ, pulsed echo transmitter - Pundit PL-200PE was used. Processing of the obtained material was performed by means of the Pundit - 200 and Pundit - 20PE working program "PL-Link". Using ultrasonic equipment, it is possible to highlight voids and cracks in the environment and study their geometrical parameters. as well as determining the mechanical characteristics of the environment. When studying the same areas, the results obtained by radar and ultrasonic methods correlate quite well with each other in terms of determining the structure and complement each other in terms of determining the mechanical parameters of the medium and details of the structure.
