Effect of Longyangxia Reservoir on the Variation of Water and Sediment

Abstract:

Longyangxia reservoir is the key project for the upper reaches of the Yellow River by possessing the interannual regulation capability. This paper analyzes the runoff sediment characteristics since the operation of the reservoir on the basis of the hydrological data before and after the operation of Longyangxia reservoir. The study result indicates that the variation characteristics of water and sediment after the operation of the reservoir mainly include sharply-reduced peak discharge, varied annual runoff distributions, reduced annual runoff coefficient of variation, obviously-reduced quantity of sediment, varied sediment runoff relation; the operation characteristics namely annual storage in flood period, level period discharge high-flow year water storage and low-flow year water supplement of Longyangxia reservoir are the key affecting factors for the variation of water and sediment.
