Abstract:The proposed Zhongqiao Reservoir is a small-sized reservoir. The necessity and task of the project construction are analyzed. The method of earth excavation and backfill in the reservoir area to decrease the engineering land is put forward. By comparing and selecting the land, sediment accumulation, hydraulic layout, water supply, flood control, investment and the other factors, the water level characteristics of the reservoir are determined in order to provide the reference for the construction of the similar reservoirs in the other areas.
