Study of the hydrogeological, engineering-geological and hydrological regime of the Kaiyndy Lake basin for an emergency spillway from Kaiyndy Lake

Abstract

This article provides information on the stability of the natural dam of Lake Kaiyndy in the study area. Lake Kaiyndy is located in the middle part of the basin and is fed by melted snow and rainwater. The flow of water from the lake is carried out by the surface. The lake belongs to the high category of mudflow hazard. During the technogenic development of this territory, one should consider the negative impact of the additional load on the stability of the sides of the canyon and not expand the development of the territory towards the river. In the event of a lake outburst, the road bridge of the village of Zhalanash - the village of Saty, residential buildings and farmland of the village of Algabas and Zhanatalap of the Kegen district, the village of Shelek, the village of Masak, the village of Baiseit, the village of Malybay, with. Zhanasharua of the Enbekshikazakh district and the Bartogay reservoir of the Almaty region, road bridges, power lines. The total number of people in the risk zone is more than 2-3 thousand people. Also, the Kuldzhinsky Trakt highways, the Western China-Western Europe auto-ban, irrigation systems, the waterworks of the Kunaev BAC and other linear communications fall into the zone of influence. Lake Kaiyndy is a place of mass visits by tourists and vacationers. In summer, the number of people at risk can reach several hundred.
