A STUDY ON RUBBER CUSHION DAM AND IT’S USING FOR COAST AND PORT ENGINEERING

Rubber cushion dams are inflatable and deflatable hydraulic structures. Thousands of rubber dams have been installed worldwide for various purposes: irrigation, water supply, power generation, tidal barrier, flood control, environmental improvement, and recreation.Rubber dams have been used for the past 40 years in river and coastal engineering applications, in all of the world and overseas. An inflatable rubber dam is basically an envelope formed from a fabric-reinforced rubber membrane which is anchored to a concrete foundation The membrane that forms the rubber dam typically is constructed with multiple layers of reinforcement fabrics such as nylon or even rubber. Despite the increasing interest for rubber dams, little information is available on their hydraulic performances. The overflow characteristics of inflated rubber dams are re-investigated. In this article the concept design method of rubber cushion dam for control the flood and surface water have been showed and discuss for using of this technology for coast engineering (especially near the bank and river side ).The advantage of this research satisfied the physical characters of Iranian ports and many other part of Persian Gulf coast.
