A Method for Determining Spillway Condition

摘要

Hydro-Quebec is testing a new method for assessing the condition of a spillway. The method uses an indexing system to objectively determine the condition of spillway components. Information from the assessment helps prioritize maintenance activities.rnOvertopping is the most frequent cause of failure of embankment dams worldwide. Failure to properly operate the spillway structure, resulting in overtopping, is due to equipment or operational deficiencies. These deficiencies can be associated with poor original design or gradual deterioration of the spillway.
