خلاصه مقاله:
In order to make the most of the potentiality available, the morning glory spillways are used to increase the viability and help increasing the water flow by making some changes in the environment. Besides, some researches have been carried out on increasing the viability of the prevailing spillways. Whirlpool in morning glory spillways may decrease both the discharge and the discharge coefficient of the spillway. Vortex Breakers are used to disrupt the whirlpool and to increase the viability of the spillways. In this research paper the quantity of the vortex breakers and their heights viability are examined on the system output and the discharge amount via a hydraulic model in 190 different researches. The result of such research shows that vortex breakers increase the discharge of the spillway. Numerous short vortex breakers can have the same effects as vortex breakers in smaller number of quantities.
