Transformations in reservoirs and flood passage in the kazakhstan part of the Esil river basin

Justify the technology for the production of hydrological and water management calculations for the passage of the maximum flow of 1% (0.1%) supply. Analyzed and summarized: methods for calculating the maximum flow in the presence and absence of anthropogenic activity; the current state and prospects of the use of water resources and the possibility of regulating and passing floods by reservoirs. At the current level, the problem of producing hydrological and water management calculations for the transformation and transmission of floods by cascade reservoirs has not been resolved. The technology for solving the transformation of floods of 1% (0.1%) of the availability of reservoirs and the possibility of combating floods with a promising level of use of water and land resources in the Esil river basin has been substantiated. It is intended for scientists, employees of design and survey and operational organizations of water management, environmental protection. The technology for calculating the transformation in reservoirs and the passage of floods in the basins of lowland rivers was developed for the first time in the Republic of Kazakhstan.
