摘要
通过三种方法分析了2012年7月下旬发生在黄河中游府谷—吴堡区间两次洪水的来源与组成,并与多场历史相似洪水对比,结果表明:该区间未控区为典型超渗产流区,其洪峰流量、径流总量与降雨量、降雨强度有密切关系;未控区是吴堡站洪水的主要来源区之一,对洪水预报精度和预见期有较大影响。初步建立了该未控区降雨径流关系。
Through applying three methods,this paper analyzed the sources and compositions of two floods which occurred in Fugu-Wubao region in the Middle Yellow River in the last ten-day period of July of 2012 and compared with some similar historical floods.The results show that： the uncontrolled zones of this region belong to typical infiltration excess runoff areas and the flood peak discharge and runoff volume are bound up with rainfall and rainfall intensity;the uncontrolled zones are some of the main flood sources of Wubao Station,which has great influence to the flood forecast accuracy and forecast period.The relationship between rainfall and runoff in the uncontrolled zones is established.
