| Description: | Technical Report Abstract: Lock gates and spillway gates are vulnerable features of navigation, flood control, and water resource projects. These structures are susceptible to damage from accidents; overloads due to natural events, lack of maintenance, or operational errors; and terrorist attack. Damage to lock or spillway gates can result in uncontrolled drawdown of pool, with possible severe impacts both upstream and downstream of the structure. Emergency gap closure systems are needed to rapidly stop flow and maintain pool and to accommodate early initiation of repairs. The literature was reviewed to identify the types of closure structures in existence and to assess their feasibility for use as emergency closures. In addition, some innovative concepts were developed, at least in preliminary form, and are presented herein. |
