The objective of the research was to study the processes of landslide, evaluate their development, and justify a set of measures for reducing the negative effects at the territory of the Rostov region. Landslide processes arise and develop at such parts of the slope where the disequilibrium of rocks exists. The disequilibrium can be caused by increased steepness of the slope as a result of washout by water, weakening of rocks under weathering or waterlogging precipitation and groundwater, influence of building and economic activity, conducted without taking into account geological conditions of the locality (destruction of slopes by road excavation, excessive irrigation of gardens, situated on the slopes, and so forth). Leading role in the region belongs to erosion processes, which are a major factor in forming the landslides in the Rostov region. Sites with linear erosion occupy more than 20000 km² (15-20 % of the region area) with a predominance of medium (1-1.5 km/km²) and high (4-5 km/km²) intensity development of the process. In the study area landslide activity is at the level of long-term average values (0.5-0.7 m/year) and occurs mainly in the middle and upper parts of a landslide, but there are areas where the horizontal displacement speed is 2.0-2.2 m/year (r.s. Shaposhnikovo, f. Pukhlyakovsky, v. Chumbur-Kosa, and other). As one of the main measures for landslide protection near Shaposhnikovo the creation of counterfort was proposed, as well as the creation of an artificial sown hollow which can withstand washout at a rate of water flow 1.1-1.3 m/sec. The system of measures against landslides should be supplemented by the complex of soil protection techniques and activities at the watershed. Reasonable set of measures enables to stabilize the landslide slope.
