مروری بر روش‌های کنترل جریان غلیظ ورودی به مخازن سدها در شرایط مختلف هیدرولیکی

Dry and semi-dry climate and lack of coordination between the time of discharge basins and expenses have been caused that managers try to control and maintenance of surface water resources through fun dams, so in way, they can meet various water needs by management and planning. But always sedimentation in reservoirs shortens the useful life of the dam. Viscous flows are the main factors of sediment transport tanks, it has been disrupted the performance of dams such as the dose, Minab and Sefidrud, so far. In addition to reducing the volume of the reservoir, viscous flows increase the speed of attrition’s turbines and decrease their efficiency and increases maintenance costs. Also, it can be followed by risk of clog ponds, bottom outlet structures or damaging to valves, has been designed for sedimentation. At the moment, the rate of loss of reservoir volume due to sedimentation in reservoirs more quickly builds new reservoirs. Hence, increasing the useful life of dams and maintaining storage volumes in water resources engineering is a vital issue for the continued operation of water control. Knowledge about the turbidity currents properties can help to manage and release these currents from dam reservoirs. In this paper, a comprehensive investigation on the studies of various methods against turbidity currents, combination methods in experimental conditions and limitations in filed applications were carried out. Also, suggestions were presented for further research on selecting methods for controlling turbidity currents.
