对黄河水沙特性变化的主要认识

Influence of Watershed Comprehensive Management on Sediment and Water Characteristics in the Region of Hekouzhen to Longmen

编者按由水利部第二届“水沙变化研究基金”和“黄河防汛科技项目”资助的《黄河水沙特性变化综合分析》课题，是黄委水科院和水文局共同主持完成的。本项目主要从河流学和河床演变学出发，充分考虑防洪、防凌和水资源的开发利用，以弄清情况、分析规律为主线，在前人成果...

Being the main source of coarse sediment and all sediment to the Yellow River, the region of Hekouzhen to Longmen is also the major source of storm flood to the lower Yellow River. Based on expounding current developing characteristics of rainfall and runoff in the region, analysis of the influence of watershed comprehensive management on runoff and sediment transport under different rainfall conditions is focused in the paper. At the same time, the relation between rainfall and flood peak discharge in storm flood period is analyzed, and the influence of watershed comprehensive management on flood is studied.
