| Popis: | The Tuyamuyun hydro-complex on the Amu Darya River, consisting of one in-channel and three off-channel basins with a design volume of 7.8 billion m3, was intended to improve the supply of irrigation water and electricity to the Khorezm region and the Republic of Karakalpakstan and to control the catastrophic floods in the lower reaches; it was put into operation in 1984. The water reservoir complex is in joint use by the Republics of Uzbekistan and Turkmenistan. Numerous measurements showed that the useful volume of the reservoir due to siltation decreased from 2.34 billion m3 to 770 million m3, i.e. by 67%. To partially compensate for the lost capacity, it was proposed to build-up the protective levees and to erect the new dams, where the topography of the area allowed. Using the GIS, the predictive volumes to increase the capacity of the Channel water reservoir have been proposed, depending on the water level in the reservoir, which between the marks ▽130.0 and ▽131.5 amounted to 527.3 million m3. The necessity was shown to increase the height of the following protective dams: No. 1 ▽134.5, No. 2 ▽134.8, No3 ▽136.7, No. 4 ▽134.4, No. 5 ▽136.4. No. 6 ▽137.9, No. 8 ▽138.6, No. 9 ▽135 and land dam 134.8. |
