Seasonal Limited Water Level Control of Reservoir Based on Flood Utilization

The development of the transit of flood resources utilization, increase of surface storage capacity, is the strategic measures to alleviate the shortage of water resources and flood multiple contradictions.Shilianghe reservoir is a large reservoir of Jiangsu Province, Lianyungang City, is also the key of flood resources utilization in Lianyungang City, through the study of the limited water level by stage has important significance to the utilization of flood resources.In this paper, on the basis of flood control operation mode and conditions in Shilianghe reservoir, according to the specific situation of the reservoir and then take into consideration all the factors related to the reservoir flood regulation, considering the flood resources utilization in flood season, which is based on the flood season staging situation of present situation of reservoir, and inquire into the various stages of reservoir design flood, flood routing, determine the limit water level by stage of the staging of Shilianghe reservoir, and calculate the efficiency of controlling the limited water level by stage, on this basis ,analysis of the influence of water level adjustment of reservoir flood control.The research results can provide a reference for the large reservoir flood resources utilization in china.
