3.6. NAVIGATION LOCKS The rubber dams of the navigation locks can be used for two purposes. The main purpose of the navigation locks is to give way for boating up and down the Gomti River. Alternatively, they can be used for head water regulation too. The mode of operation can be switched by setting the operational state either to “N”, for navigation lock mode, or to a priority for head water regulation. Since the weir heights of the navigation lock rubber dams differs from the height of the main weir sections, navigation lock rubber dams cannot have similar priorities as any main weir section. The navigation locks are controlled by the Control & Regulation Shaft System (CRS). Each rubber dam section in the navigation locks can be operated independently. In principle the CRS for the navigation lock systems is the same as for the 4 main weir sections.
