Preventive emptying of lakes in moraine-glacial complexes is a crucial measure for reducing the damage caused by debris flows. The selection of an optimal emptying method requires consideration of the morphometric characteristics of moraine-glacial complexes, use of water flow energy, application of explosives, and mechanized earthworks.

The debris flow on 23 July 2015 in the Kargalinka River basin significantly differed from typical debris flows of the Ile Alatau due to unique triggering factors and flow characteristics. The flow rate did not exceed 100-150 m³/s. Partial filling of the debris reservoir with silt caused secondary debris flow formation, resulting in substantial economic damage.

Preventive emptying of surface reservoirs on moraine-glacial complexes to reduce debris flow risk should account for natural processes of lake evolution and outburst. The article examines the case of Lake 13-bis on the Sovetov Glacier and provides recommendations for optimizing future work.

The results of preventive emptying of lakes in the Issyk, Bolshaya Almatinka, and Malaya Almatinka river basins are presented. The findings suggest that incomplete emptying of hazardous lakes can lead to catastrophic consequences.

Climate warming since the Little Ice Age led to the formation of reservoirs on moraine-glacial complexes in the Zailiysky Alatau. Breakouts of these reservoirs caused catastrophic debris flows in the mid-20th century. Initially, rainfall-induced debris flows were the main concern, with large check dams forming the core of defense strategies. However, increased glacially-induced debris flows necessitated new approaches, including small reservoirs in high-altitude zones and preventive measures to empty hazardous moraine lakes.

The book provides a systematic description of debris flow nature in the Zailiysky Alatau. It includes an anthology of catastrophic debris flows, evaluation of protective measures for Almaty, and conceptual frameworks for debris flow prevention under global warming.

The book examines the nature of debris flows, the impact of natural and anthropogenic factors on debris flow processes, rheology of debris flow material, and key patterns of debris flow origin, development, and deposition. It also evaluates debris flow hazards, describes countermeasures and engineering solutions, and presents a concept for debris flow protection on the northern slopes of the Ile Alatau under changing climate conditions.

Natural Debris Flows and Field Experiments in Kazakhstan compiles research on debris flows, originally published in Russian (1976–1992). It covers field experiments at the Chemolgan test site, seismic signal analysis, and large-scale natural debris flows triggered by glacial lake outburst floods. The volume translates Soviet-era findings, offering insights into debris flow activity in the Zailiysky Alatau Mountains.
