Study on Fusegate as a New Phenomenon Gates for Sarough Water Reservoir Dam in West Azarbaijan –Iran

Sarough dam is located in West Azarbayjan province in 17.5 km north of Takab city and 2 km south west of googerdchi river.it is a new dam for irrigation and water supply. The embankment is rock & earth fill with a central clay core, its maximum height is67.5 m above the bed rock, its crest length is 418 m and the reservoir storage has avolume of 40 mcm. Fusegates have been selected as a spillway control system because of the particularhydrology of the site: there is less than 6 hours between the beginning of the flood and the peak of the flood. Therefore, there is not enough time to act in case of mechanicaldysfunctioning, power shortage or misoperation of the conventional mechanical gates. A total of six Fusegates (type Narrow Moderate Head), each 3,50m high, 3,50m widehave been accommodated on the 26m long broad crested weir of Sarough dam. Theweir is divided in 3 spans by two piers 2,50m wide. The Fusegates will form a watertight barrier, thus raising the permanent pool up to the level of their overspillingcrest at 1841,30m.
