Abstract
Passing of debris floods over spillways and stilling basins of the diversion dams in steep channel of the mountainous rivers causes abrasion of spillways and stilling basins. This type of spillways and stilling basins abrasion has been reported in different countries including Iran. The purpose of this research provides a method for analyzing the destructive effects of debris floods passing over concrete diversion dams’ weirs. Thus, in this research the proposed empirical equations by the authors are evaluated using field data and an algorithm is provided for estimation of the abrasion of diversion dams’ stilling basins. Roozbahan Diversion Dam in FarsProvince is selected as case study to evaluate the ability of proposed algorithm for estimation of abrasion of a real case. Then, abrasion of Roozbahan Diversion Dam by floods 1995 to 1999 is calculated and compared with real abrasion percentage. For this propose, debris flood is simulated and velocity, sediment size, and impact energy of passing sediment over Roozbahan Diversion Dam are estimated. Then, the abrasion of the concrete slab of stilling basin of the dam is provided by using the empirical equations. This research shows that the estimated abrasion percentage by proposed algorithm has acceptable agreement with real case
