Abstract :

the sediment accumulation in the reservoirs places upstream and downstream of the dam under the influence of ecosystem changes. In order to increase the volume of regulated water in the river basin and prevent the introduction of river sediments into the dam reservoir and as a result of increasing the useful life of the dam and the optimal management of water resources in the given time, the required data from the relevant companies from the Tangab Dam was obtained and Using Karun's analysis software, based on the calculations performed by the software, the modified volume (after sedimentation) after one year and after 50 years from the beginning of operation, using the method of increasing the level to The order of 1021.646 million cubic meters and 605.664 million cubic meters, and also for the method of reducing the level of these numbers is equal to 1021.6 million million Rmkb and 064/580million cubic meters is estimated. Given the reservoir type and sediment volume, the curves of hp and h'p are plotted. According to the power plant's level, the reservoir level of the dam increases with the calculation of sediment distribution by increasing the level after 110 years from the plant's level of utilization, and this also occurs in the method of reducing the level after 100 years.
