COMMISSION INTERNATIONALE DES GRANDS BARRAGES ------- VINGT-SIXIÈME CONGRÈS DES GRANDS BARRAGES Autriche, juillet 2018 ------- RUBBER DAM CONSTRUCTION WITH NAVIGATION LOCKS Paul OBERLEITNER & Rudolf FRITSCH Partner & CEO Hydro-Construct GmbH AUSTRIA 1. INTRODUCTION Gomti River is a main river in India and is passing the main capital Lucknow in the Indian State Uttar Pradesh. The State Irrigation Department has developed a river rejuvenation program with the following topics:  Upgrading of the existing Gomti Weir downstream of the Gomti Barrage with a flexible weir structure  Upgrading comprises also the development of weir cascades  Improvement of the flood safety by structuring of the river banks  Creating a water surface with a reservoir with app. 400.000 m³ with a constant water level  Improvement of water quality in the river stretch by collecting and diverting of the sewage in a new pipe system  Enabling river boating in the reservoir and passing of boats through the new weir by navigation locks Alternative Studies carried out came to the solution that a flexible rubber dam with a water filled regulation system meets the requirements as it bests to reach the outlined targets and the economic feasibility. The rubber dam system on the weir is added by navigation locks on both river banks for passing of boats. In the navigation locks there are also moveable rubber dams installed. 1394
