前言黄河为害,病在泥沙。人民治黄三十多年,在防洪、发电、灌溉方面成绩巨大,但在泥沙的处理和应用方面,水土保持、水库拦沙、自然两岸放淤、排沙入海等,实践证明都不能满足根治黄河的要求,且打了不同程度的败仗。笔者认为,利用高含沙水流治理黄河是新的方向,在小浪底水库采用高浓度调沙放淤的方案,将可以彻底消除下游灾害为黄河水沙资源利用创造条件。调沙放淤是在高浓度含沙量水流情况下输送的,其特点是水沙分别处理,放淤渠走高含沙水流,黄河下游行清水。其优点是:①节约水量,如10亿吨沙量以往需水300亿
Preface Yellow River damage, sick in the sediment. Over the past 30 years, people have achieved great achievements in flood control, power generation and irrigation. However, in terms of sediment treatment and application, water and soil conservation, reservoir silt arresting, siltation detention on both sides of the Taiwan Strait and sediment discharge into the sea have failed to meet the needs of radical treatment Yellow River requirements, and played a different degree of defeat. The author believes that the use of high sediment flow to the Yellow River is a new direction, the Xiaolangdi Reservoir using high concentrations of sediment adjustment program will completely eliminate downstream disasters for the Yellow River water and sediment resources to create the conditions. Sediment release Sediment is transported in the condition of high concentration of sediment flow, which is characterized by separate treatment of sediment and sediment, sediment discharge and sediment discharge, sediment discharge and sediment discharge in the lower reaches of the Yellow River. Its advantages are: ① save water, such as 10 million tons of sand in the past need water 30000000000
