Study of local erosion and development of effective structures of transverse bank protection structures

Protection of coasts from erosion and the associated landslide destruction of coastal territories is a pressing socio-economic and environmental issue that hinders the development of recreational and other resources of the coastal strip of the Republic of Kazakhstan. The use of modern computational systems provides the new possibilities for designing engineering structures for bank protection, which allows simulating the stress-strain state of the "foundation– protective structure" system in a wide range of loads, both at the construction and at the operation stage. The scientific novelty is conditioned by the fact that this study investigates the processes of bank erosion and the hydraulic bank protection structures on rivers of the foothill zones. For this purpose, it is necessary, first of all, to conduct a number of experiments to identify the effect of river abrasion on the stability of the territory, especiallyin the foothill zones, where landslides are widespread. Such areas consist mainly of loessial soils, which, due to moisture, on the one hand, and the impactof rivers on the other, cause the deformation of the soil mass and bank slough, which indicates insufficient knowledge of this issue and the need to take preventive measures to ensure the stability of the territory. The practical significance of the study is determined by the fact that the findings can be used to improve bank protection structures during construction work on rivers in foothill zones.
