Ecological and engineering solutions for the reconstruction of anti-mudflow hydraulic structures of the Crimea

The article studies the territorial features of the formation of a dangerous process - mudflows. The factors of mudflow hazard formation are described, the classification and characteristics of mudflows formed in the Crimea are given. The methods of studying mudflows are considered, the parameters of the mudflow are calculated on the example of the Shelen River, on the basis of which options for the reconstruction of existing mudflow protection structures are proposed. The purpose of the article is to substantiate environmental engineering solutions for the reconstruction of anti-mudflow hydraulic structures in mudflow-prone Crimean river basins. The object of research is the basin of the Shelen River typical for the South-Eastern rural area. The purpose of the research is to substantiate technical solutions for the reconstruction of anti-mudflow structures in the Shelen River basin. Research objectives: to study the conditions for the formation of Crimean mudflows, the history of research and classification; consider existing methods for studying mudflow hazard and calculation methods for determining the parameters of mudflows; to characterize the current state of anti-mudflow structures on the example of the Shelen river basin; justify decisions on the reconstruction of anti-mudflow structures and develop recommendations for their restoration. In the article, on the basis of field studies, hydrological flood flow rates, annual runoff volumes, water flow rates and volumes in years of different water content and average monthly water flow rates using the Shelen River basin as an example, the mudflow parameters are calculated. Anti-mudflow structures were identified and their condition was analyzed. Based on the results of the study, proposals and environmental engineering technical solutions for the reconstruction of existing anti-mudflow structures were develope
