Abstract

Precipitation washout is a common and effective measure to restore the storage capacity of reservoir. In order to study erosion effects under the condition of different boundary conditions, control water level and flood duration in later sediment retaining period of Xiaolangdi Reservoir flood duration, four groups of precipitation washout tests were conducted. The paper analyzes reservoir erosion effects of the different group. In this paper, the result show that, with more discharge and sediment, lower water level, longer duration and higher deposition surface, the more scour depth and better effect will be obtained. Based of experiment data, the relationship between output sediment discharge rate and input discharge, sediment concentration and water gradient is obtained and verified by measured data of Sanmenxia Reservoir, and the relationship between cumulative erosion and input water and sediment amount and water level before dam are obtained.
