Flood - Volume Analysis and Efficiency of The Dam Spillways
Abstract
Past experience and statistical data show that extreme floods constitute an important risk for the hydrological safety of dams. Overtopping represents more than 40% of dam failures in the world, and has been also cause of many other accidents. For this reason, the problem of selecting the appropriate design flood is a constant concern to dam engineering. This concern is even more important for those dams that are also explicitly committed to flood control target. In the present talk we investigate the hydrological safety of dams checking the efficiency of the dam spillways. A new statistical procedure based on the flood-volume analysis is developed. An application to Ceppo Morelli dam, on Anza river basin, in Piedmont, Italy, is given.
