Gravitational movement of soils on slopes and their influence on the condition of water bodies

Abstract

The purpose of the research is to study the features of the movement of particles, aggregates and geological bodies (landslides) downhill under the influence of a number of natural and man-made factors, to study the most common natural and man-made objects that reduce the activity of the development of slope processes. Two of the most common slope exogenous geological processes are considered – surface flushing and landslide. These processes contribute to the entry of silt fraction into the sediments of water bodies. The study of pollution of water bodies with heavy metals still remains relevant when assessing the geo ecological state of the environment. On the Volga River basin the principles are proposed and the zoning is presented. According to natural and technogenic objects, four categories of sites were allocated hierarchically for monitoring the pollution of the territory with heavy metals. The zoning of the bed of water bodies for the distribution of silty sediments – sorbents of pollutants was carried out. The elements of the energy approach are presented, giving an understanding of the most likely locations of pollutants – energy traps and potential barriers. Practical examples of the spread of pollutants in the natural and man-made environment and the interaction of natural and man-made processes in the landslide system are given. For the landslide process, the most typical interactions between a geological body and man-made objects are presented. On the example of the most typical landslides for the European part of Russia, the measures aimed at their stabilization, as well as the impacts contributing to their activation, are presented. Natural and man-made potential barriers to the landslide process are considered.
