摘要:
以四川省都江堰市龙池镇水打沟泥石流流域为研究区,利用遥感影像与GIS技术提取流域信息,基于HEC-HMS分布式水文模型,模拟了"2010-08-13"泥石流的暴雨汇流过程,并综合考虑泥石流的特征参数,从最大流量角度初步研究水打沟泥石流的汇流过程;探讨了研究区土地利用情况、模拟降雨时间及暴雨频率对泥石流汇流过程的影响,从而揭示三者与汇流过程之间的内在联系。研究结果表明:泥石流20 a一遇峰值流量为53.49 m3/s,灌木林将峰值流量降低24%,而休耕地的峰值流量提高70%。100 a一遇的暴雨,泥石流峰值流量增加到70.62 m3/s,同比增长32%,50 a一遇的增长23%,10 a、5 a...
Abstract:
In this paper, Shuida gully in Longchi town, Dujiangyan city, Sichuan Province,China was selected as study area, it applies the remotesensing image and GIS technology to extract the watershed information of the study area and use the distributed hydrological model HEC-HMS to simulate the rainstorm conflux process of Shuida debris flow on August 13, 2010，and the conflux process of debris flow was studied preliminarily by considering the characteristic parameters of debris flow comprehensively; The effects of land use type, simulating rainfall time and rainstorm frequency on conflux process of debris flow were analyzed. It revealed the intrinsic link between three factors and conflux process. The results show that the peak discharge with a return period of 20 year for Shuida debris flow on August 13, 2010 was measured at 53.49 m3 / s. The land use types also have an influence on debris flow discharge; their analysis show the Shrub reduces 24% of the peak discharge. However, discharge for fallow land increases by 70%. The peak discharge with 100-year return period increases to 70.62 m3 / s, which increases by 32 % of the peak discharge. The peak discharge with 50-year return period increases by 23 %, while 10-year return period and 5-year return period reduces 4% and 16% of the peak discharge respectively; When the total rainfall is certain, increasing the simulation rainfall time before and after the outbreak of debris flow signally has little influence on the peak discharge, and the influence of rainfall before the outbreak of debris flow on conflux is greater than the rain after the outbreak of debris flow.
