Detection and Evaluation of Scour protection for Navigation Dams
Scour occurs in the vicinity of essentially every navigation dam constructed. Scour in this report refers to the displacement of natural or engineered materials by flowing water in the vicinity of a navigation project. The severity of the scour depends on many operational and site conditions. To maintain the functional performance of the project, detection and evaluation of the scour and repair or replacement of the scour protection near these locks and dams are necessary. If severe scour exists, rehabilitation of the dam and appurtenant structures may be needed to maintain the structural integrity of the dam. Periodic inspections using hydrographic surveys and divers have typically been used to assess the condition of the need for repair. These methods do not always provide enough information to adequately assess the extent of scour and the repair and/or rehabilitation requirements. This report describes other methods to assess the condition of the existing scour protection and provides examples of reliability analyses that can be used for risk-based decision making.
