Abstract

Now a day, the role of dams in the human life especially in countries like Iran is known as one of the underlying bases of sustainable development. The spillway is one of the important structures of any dams, that enables the bypass of flood flows or flows that exceed the capacity of the dam. Among the different types of the spillways, OGEE SPILLWAYS are mostly used, regarding their high hydraulic efficiency. The most precise method in studying the problems of this structure, is making PHYSICAL MODELs and modeling real flows. In order to investigate the FLOW REGIME on a part of MOLLASADRA DAM ogee spillway, the PHYSICAL MODEL of the spillway was built to a 1:30 scale in the flume of the hydraulic laboratory of Marvdasht Islamic Azad University. Data was gathered with different discharges. Analyzing the gathered data by means of hydraulic regimes, it was found that the energy dissipater structures are working properly, due to tested discharges. The C coefficient of the ogee spillway was computed to be 2.86. In addition the regime of the flow was modeled up to the discharge of about 1680 m3/s in the prototype, but we did not see any special hydraulic problem.
