Description: Das Projekt "Inflatable weir for a hydro electric station" wird vom Umweltbundesamt gefördert und von Floecksmühle Ochtendung durchgeführt. Objective: To demonstrate regulation of hydraulic conditions at a hydro station using an inflatable weir for reduced civil costs and for improved water control. General Information: An 16m wide inflatable weir, with an overflow level of 1.4m, was installed to provide a suitable operating head for a low-head hydroelectric schemes. The weir comprises an inner section which can be filled with water and an air-filled outer section, which can be attached to a suitable base. By control of the inner section, the weir may be varied in shape and can be used for effective control of the turbine hydraulic head. This allows improved exploitation of the energy resource by optimising system operating conditions. Hydraulic conditions: flows 7.32 m3/s head 4.5 m rating 240kW Achievements: The original 10m wide, 1m overflow level scheme was abandoned in favour of the present site because of excessive projected costs and because of difficult hydraulic conditions. The present scheme was installed by September 1987 and, although some technical difficulties have had to be dealt with, the plant has operated successfully. Prime Contractor: Ingenieurbüro Flocksmühle; Ochtendung; Germany.
