Transfer of Amudarya flowing part to increase the supportability of the Uzbekistan southern regions

Abstract

Abstract The issues of the availability of irrigation water in the southern regions of Uzbekistan, the existing problems in machine irrigation systems, as well as the disadvantages and advantages of the proposed solutions, are analyzed. In analyzing the current situation, a systematic approach was used to address the issue of the availability of irrigation water in the southern regions of Uzbekistan. When choosing the most optimal options for laying the channel, modern methods of GIS technology were used. A situational analysis showed that water availability in the southern regions of the republic is complicated by the change and violation of the hydrological regime of the river basin by the construction of large reservoirs in its upper reaches. To solve problems with the security of the southern regions of the republic, a new concept is proposed for transferring part of the river flow. The proposed new concept of the transfer option differs from the previous ones by a) There are no additional costs for renting the territory of Turkmenistan; b) Conditions are being created for the development of various infrastructures in the southern regions of the republic; c) The construction of a reservoir on the territory of the Surkhandarya region will allow the danger of overflow of the Tuyamuyun reservoir in the winter and increase water supply to the Surkhandarya, Kashkadarya and Bukhara regions of the republic.
