摘要
针对小流域下垫面条件复杂,传统的单一模型不足以快速准确地进行山洪预警的问题,将小流域虚拟为一个水库模型,提出利用蓄满-超渗混合模型,对不同土壤含水率下的净雨分析结果进行产流计算,将流域降雨产流过程模拟为水库蓄放水过程,根据实时降雨量准确计算出流域出口断面的洪水要素。在武汉市黄陂区肖家寨的应用结果表明,该方法合理可靠,为无资料地区小流域山洪预警提供了新思路。
In view of the complicated conditions of the underlying surface in the small watershed,the traditional single model is not enough to accurately and quickly carry out the problem of mountain flood warning.The small watershed is virtualized as a reservoir model,and the full storage excess infiltration hybrid model is proposed for different soil water content.The mixed model is used to analyze the net rain analysis and calculate the runoff.The rainfall production process in the basin is simulated as the reservoir storage and release process.Based on the real time rainfall,the flood elements of the outlet section of the basin is accurately calculated.The application in Xiaojiazhai of Huangpi District,Wuhan City shows that the method is reasonable and reliable,and provides a new idea for mountain flood warning in small watersheds with no data.
