DETERMINATION OF SIGNIFICANT FACTORS OF LANDSLIDE PROCESSES AND FLOODING

The linear dependence of some geological (significant) factors responsible for landslide and flooding processes on the cost of geotechnical surveys determining these factors was proved. The principle of selection of engineering-geological surveys, which assess the factors of occurrence of landslide and flooding with high probability, was developed. The possibility of identifying economic territories that may be susceptible to landslide and flooding processes based on already existing basic data of previously conducted engineering-geological surveys is substantiated.

The method for monitoring of rivers in urban areas

In this paper the technique for monitoring the displacement channel of rivers in urban areas. Monitoring conducted by the example of the river Stryy within the city and nearby villages, covering a 30-year period – from 1979 to 2010. The main causes of riverbed displacement is described. The monitoring methodology is based on usage data from space imaging, cartographic materials, including special maps – the soil and geologic maps of quaternary sediments and, also engineering and surveying data.

Method of research of displacements of Dnister riverbed

In this paper we study the technique of channel displacement of the Dniester River. Monitoring of the rivers was done for the territory within the villages Tershev and Busovisko, and covers a 30-year period – from 1979 to 2010. The main causes of river bed displacement. We propose a conceptual model of the study of channel displacement, which is based on usage data from space imaging, aerial photography, laser scanning, cartographic materials, including special maps – the soil and geologic maps of quaternary sediments and, as well as data engineering and surveying..
