A need to estimate a hazard of a mudflow stream appearance in the glacial-nival zone of the Northern slope of Zailiyskiy Alatau (Kasakhstan) is now one of the really urgent problems. The objective of this study was to invesβ tigate influence of glacial and hydrometeorological factors on the condition of snow-glacial zone of Zailiyskiy Alatau and find out a mudflow-forming role of the mudflow centers arising due to climate warming and degraβ dation of glaciation: periglacial lakes, intramoraine channels and reservoirs, and also talik massifs of morainic deposits. We analyzed glacial processes in the Zailiysky Alatau over a long period using meteorological data of the Almaty weather station and its close correlations with data from weather stations in the mountains. The area of glaciations was found out to be reduced after the maximum of the Little Ice Age. A combined diagram of occurrence of the mudflow manifestations and factors causing them had been constructed on the basis of staβ tistical data on the landslide phenomena. Glacial mudflows were the most frequent in 1960β1990, and later on activity of them became weaker. We believe, that in the next 10β20Β years, the glacial mudflow hazard in Zailiysβ kiy Alatau can sharply decrease, but at the same time, a probability of occurrence of the rainfall mudflows can increase in the mountainous zone of the ridge due the increase of areas with melted moraine and slope deposits.ΠΠ»Ρ ΡΠ΅ΡΡΠΈΡΠΎΡΠΈΠΈ ΡΠ΅Π²Π΅ΡΠ½ΠΎΠ³ΠΎ ΡΠΊΠ»ΠΎΠ½Π° Ρ
