The Change Of Water And Sand In Yellow River, And The Coast Corrosion Trend In Delta

Yellow River Delta is a famous one in the world, which is enriched in abundant minerals, marine creatures and land resources. Meantime, because of its special geographic location, it has the potential of exploration and development.In the past ten years, many institutions had done research about the prediction of coast corrosion and aggradations and made some achievements. But, there is short of integrated analysis of multi-factors and defections about fundamental research.The increasingly corrosion makes the exploration of oil field difficult. The progress of making land toward sea is delayed by the direct result of the change about water and sand. Besides, the short of fresh water deteriorates the environment of Yellow River Delta and disturbs the order of life and work. It also affects the ecology environment.This paper gives proposal of the reasonable distribution and use of the water and sand resources. It is important to stabilize the estuary, ameliorate the ecology environment and reduce the impact to the lower river way.It is the integrated method to consider stabilizing the route of Yellow River into sea. The problem of corrosion and aggradations can be dealt with by measure of combining several reservoirs to regulate water and sand resources. It needs the long-term plan and big investment to prevent and reduce the marine disasters.What is the most important is to clarify the law of evolution of Yellow River Delta by watching and research.
