Study on the water allocation scheme of the Yellow River in non-flood season

摘要

Water shortage, water quality deterioration and flood disaster are three serious problems of the Yellow River basin. Since the 1990s, flow cutoff occurs frequently in the lower reach. The exhausted river water can not meet the increasing water demand, which seriously restricted the economic development of the river basin. The Yellow River Conservancy Commission (YRCC) developed the water allocation scheme in 1998, which was the first effort to put integrated flood control, water resources management and river management in the whole river basin in China. In this paper, the principles and the operation of the water allocation scheme is explained, and methods of the water allocation scheme and procedure are discussed. Optimization model and simulation model are applied in reservoir regulation, but both models have advantages and disadvantages. Some drawbacks of these models and methods for improvement are also discussed in this paper.
