黄河为害,病在泥沙,它使河床不断淤高。这种慢性病是人们所公认的。名为黄河的河水自然含有泥沙。但由于河水的含沙量不同,带来黄河防洪情况完全不同。我们把含沙量高于500公斤/立方米的水流称为高含沙洪水,也称为黄河特殊洪水。特殊洪水特殊在哪里?只有将高含沙水流特征交代清楚,才能明白特殊洪水的内在机理。高含沙水流是一种具有屈服值的结构流。一般
Damage to the Yellow River, sick in the sediment, it makes silt constantly high silt. This chronic disease is well recognized. The river named Yellow naturally contains sediment. However, due to the different amounts of sediment in the river, flood control in the Yellow River is completely different. We call the flow of water with a sediment concentration above 500 kg / m³ as high silt flood, also known as the Yellow River special flood. Where is the special flood? Only when the characteristics of high-silt water flow are explained clearly, can we understand the inherent mechanism of special flood. High silt water flow is a structure flow with yield value. general
