【摘要】：隨著人類活動(dòng)的增加半干旱半濕潤(rùn)地區(qū)小流域的山洪災(zāi)害給當(dāng)?shù)氐娜嗣裨斐闪嗽絹?lái)越多的人員和經(jīng)濟(jì)的損失。有效的對(duì)山洪災(zāi)害進(jìn)行模擬和預(yù)報(bào)能在一定程度上減少這些災(zāi)害的損失。半干旱半濕潤(rùn)地區(qū)產(chǎn)匯流過(guò)程相對(duì)復(fù)雜,往往同時(shí)存在蓄滿產(chǎn)流和超滲產(chǎn)流。加之這類地區(qū)往往都是無(wú)資料或是少資料的地區(qū),因此用傳統(tǒng)的方法很難對(duì)這類地區(qū)進(jìn)行洪水預(yù)報(bào)。水文模型的出現(xiàn)為這類問(wèn)題的解決提供了新的途徑。HEC-HMS模型是美國(guó)陸軍兵工團(tuán)最新研發(fā)的半分布式水文模型,模型中集成了大量的水文計(jì)算方法可以對(duì)濕潤(rùn)地區(qū),干旱地區(qū)以及半干旱半水潤(rùn)地區(qū)進(jìn)行很好的模擬。本研究首先使用HEC-GeoHMS模塊對(duì)研究區(qū)的基礎(chǔ)DEM數(shù)據(jù)進(jìn)行處理,經(jīng)過(guò)填洼,提取水系,劃分集水區(qū)以及劃分子流域等步驟將研究區(qū)劃分為13個(gè)子流域。在氣候模型中運(yùn)用雨量站權(quán)重法進(jìn)行降雨的點(diǎn)面插值,具體權(quán)重使用泰森多邊形法計(jì)算。本研究模擬過(guò)程中的產(chǎn)流計(jì)算采用SCS-CN法,匯流計(jì)算采用斯奈德單位線模型,河道演算采用延遲模型。在對(duì)相關(guān)參數(shù)進(jìn)行估算后,運(yùn)用研究區(qū)的兩場(chǎng)洪水進(jìn)行了模擬并對(duì)相關(guān)參數(shù)進(jìn)行了率定。其中,參數(shù)的率定采用人工率定與模型自動(dòng)優(yōu)化相結(jié)合的方法。運(yùn)用研究區(qū)的另一場(chǎng)洪水對(duì)率定的參數(shù)進(jìn)行了檢驗(yàn),檢驗(yàn)結(jié)果為:流域出口徑流深誤差為3.4%,洪峰流量誤差為19.7%,峰現(xiàn)時(shí)間誤差為1小時(shí)。模擬結(jié)果符合水文情報(bào)預(yù)報(bào)規(guī)范(SD 138-85)中的相關(guān)規(guī)定。因此,HEC-HMS模型可以對(duì)半干旱半濕潤(rùn)地區(qū)的山洪進(jìn)行較為理想的模擬,具有推廣使用的價(jià)值;本文對(duì)相關(guān)參數(shù)的率定結(jié)果對(duì)今后的研究具有一定的參考價(jià)值。
[Abstract]:With the increase of human activities, mountain torrents in small watershed in semi-arid and sub-humid areas have caused more and more human and economic losses to the local people. Effective simulation and prediction of mountain torrents can be carried out to a certain extent. Reducing the losses of these disasters. The process of producing and confluence in semi-arid and sub-humid areas is relatively complex. There is often a combination of overflowing and overflowing, and these areas tend to be areas where there is no or little information, Therefore, it is difficult to forecast flood in this area by traditional methods. The emergence of hydrological model provides a new way to solve this kind of problem. HEC-HMS model is a semi-distributed hydrological model developed recently by US Army Corps. A large number of hydrological calculation methods are integrated into the model to simulate the wet, arid and semi-arid and semi-humid areas. In this study, the basic DEM data of the study area are processed by HEC-GeoHMS module and then filled in. The study area is divided into 13 subbasins by extracting the water system, dividing the catchment area and dividing the sub-watershed. The rainfall station weight method is used to interpolate the rainfall point surface in the climate model. The specific weight is calculated by Tyson polygon method. In this study, SCS-CN method is used to calculate runoff, Snyder unit line model is used for confluence calculation, and delay model is used for channel calculation. In this paper, two flood events in the study area are simulated and the relative parameters are determined. The parameters are determined by the combination of artificial rate determination and model automatic optimization. The parameters of the rate determination are tested by another flood in the study area. The results of the test are as follows: the depth error of outlet runoff is 3.4, Hong Feng's discharge error is 19.7and the error of peak time is 1 hour. The simulation results conform to the relevant provisions of the hydrological information forecasting standard (SD 138-85). Therefore, the HEC-HMS model can be used to deal with semi-arid. The mountain torrents in sub-humid areas are simulated perfectly. This paper has some reference value for future research.
