水文與水資源水文預(yù)報課設(shè)報告

1、精選優(yōu)質(zhì)文檔-傾情為你奉上水文預(yù)報課程綜合實訓(xùn)任務(wù)書 一、實訓(xùn)任務(wù)本次實訓(xùn)的任務(wù)主要包括以下兩個方面：（一）編制伊河欒川以上流域降雨徑流量預(yù)報方案（二）編制伊河欒川以上流域降雨徑流過程預(yù)報方案二、實訓(xùn)目的水文預(yù)報課程是水文水資源專業(yè)的核心技能課程，通過水文預(yù)報綜合實訓(xùn)，能進(jìn)一步掌握水文預(yù)報的基本理論和基本方法，培養(yǎng)依據(jù)設(shè)計任務(wù)和所給資料，運用所學(xué)知識和規(guī)范，編制水文預(yù)報方案的專業(yè)技能，同時提高技術(shù)報告的編寫能力和計算機(jī)的應(yīng)用能力。在業(yè)務(wù)組織能力和實際工作能力方面得到全面鍛煉，為畢業(yè)后直接頂崗參與水文預(yù)報工作奠定基礎(chǔ)。三、流域概況（一）流域自然地理概況：伊河欒川水文站建于東徑北緯33047，是伊

2、河上游的第一個水文站，集水面積340平方公里，河長36.9公里，流域內(nèi)屬石山、林區(qū)、縱坡較陡、森林茂密，植被率在50%左右，土層覆蓋較薄，表層土為壤土，下層為沙卵石，下滲能力較大，河道比降陡，河網(wǎng)密度大，河系呈扇形。伊河流域的氣候變化，完全受季風(fēng)的支配，每年的9月份以后季風(fēng)逐漸南退，地方冷空氣不斷南下，則為北方冷高壓所控制造成季風(fēng)寒冷，雨雪稀少的干燥氣候，6月份以后，夏季風(fēng)開始活躍，南方暖濕空氣不斷襲來，形成了夏季炎熱，而潮濕的多雨氣候。 流域內(nèi)各站多年平均降水量700800毫米，610月為汛期，汛期雨量占全年的60%以上，78月為暴雨期，暴雨歷時短，強度大，一般降雨歷時一至兩天，超過三天以上

3、很少出現(xiàn)，暴雨中心多在欒川、陶灣。伊河洪水為暴雨所形成，受降雨特性影響，洪水過程陡漲陡落，洪水多發(fā)生在 710月份，特大洪水發(fā)生在78月份。流域內(nèi)水系和站網(wǎng)分布見下圖。（二）流域內(nèi)水系和站網(wǎng)分布：四、采用資料(一) 編制方案采用的資料有：1流域出口斷面逐時流量；2流域內(nèi)雨量站逐日降水量；3流域內(nèi)雨量站逐時降水量；4實測蒸發(fā)皿日蒸發(fā)量。五、產(chǎn)流方案的編制各站累計雨量摘錄表日期時間欒川站年月日起迄PP19647269163.1 3.1161811.0 14.118206.4 20.520225.7 26.2272243.4 29.6467.0 36.66814.6 51.28168.9 60.12
