Abstract

Mudflow risk management measures in the study area consist of assessment and mapping of mudflow hazard and risk, preventive measures, monitoring, early warning, construction of mudflow protection structures. Due to global warming and intensive development of the Ulken and Kishi Almaty river basins, it became necessary to determine the criteria affecting the occurrence and development of mudflow hazards in the territory and assess the degree of their impact. This article defines the criteria of mudflow hazard, taking into account the mudflow-forming factors and mechanisms of the mudflow occurrence, as well as criteria aimed at determining the vulnerability of the territory to a mudflow due to the features that create conditions for the formation of a mudflow in the zones of origin, transit, deposition of a mudflow, as well as recipients in the zone of impact of a mudflow. As a result, a large-scale (1:25000) map of the mudflow hazard and vulnerability of the territory was created on the basis of a multi-criteria decision-making method. The developed maps play an important role in planning actions to reduce, early warning and prevent the negative consequences of mudflow.
