Abstract

The Karun River is oriented from Zagros Mountains. In the MARED pump station, flat dam and waterway should be constructed to prohibit the intrusion of Persian Gulf tide waves. First layout belonged to SWECO consulting engineering in 1975 that were decided to build ship lock and dam by cubic concrete boxes as the main structure. Dam bed should be stabled to pass barges through waterway (500 tons capacity) and concrete piles ($30ˏ000ˏ000 in 2010). Second scheme of dam and waterway were designed to make with steel pipe piles, steel gates, concrete walls and embankment at 2018 more than $100ˏ000ˏ000 cost. Invention design could be replaced in the MARED dam and waterway. Floating steel gates must be rotated vertically by AI Designing. Steel gates shall be designed to add air inside the gate body. Movable gates are simulated through the fish swim bladder to operate the system that can be adapt with the water fluctuation. Air could be inserted into the simulated swim bladder by the compressor to buoy the gates. Also, it can be discharge the air automatically when the water level needs to be down. The effective depth is more than +18m therefore floating gates should be made by the hollow steel box. The total cost of the third scenarios may be estimated less than $10ˏ000ˏ000 for AID at 2023. Main dam was made to reduce costs using the pipes piles and buoyancy gates. Sediment flow can easily pass through the dam bottom and monitoring floating gates.
