水文与水资源水文预报课设报告

1、水文预报课程综合实训任务书 一、实训任务本次实训的任务主要包括以下两个方面：（一）编制伊河栾川以上流域降雨径流量预报方案（二）编制伊河栾川以上流域降雨径流过程预报方案二、实训目的水文预报课程是水文水资源专业的核心技能课程，通过水文预报综合实训，能进一步掌握水文预报的基本理论和基本方法，培养依据设计任务和所给资料，运用所学知识和规范，编制水文预报方案的专业技能，同时提高技术报告的编写能力和计算机的应用能力。在业务组织能力和实际工作能力方面得到全面锻炼，为毕业后直接顶岗参与水文预报工作奠定基础。三、流域概况（一）流域自然地理概况：伊河栾川水文站建于东径110036北纬33047，是伊河上游的第一个

2、水文站，集水面积340平方公里，河长36.9公里，流域内属石山、林区、纵坡较陡、森林茂密，植被率在50%左右，土层覆盖较薄，表层土为壤土，下层为沙卵石，下渗能力较大，河道比降陡，河网密度大，河系呈扇形。伊河流域的气候变化，完全受季风的支配，每年的9月份以后季风逐渐南退，地方冷空气不断南下，则为北方冷高压所控制造成季风寒冷，雨雪稀少的干燥气候，6月份以后，夏季风开始活跃，南方暖湿空气不断袭来，形成了夏季炎热，而潮湿的多雨气候。 流域内各站多年平均降水量700800毫米，610月为汛期，汛期雨量占全年的60%以上，78月为暴雨期，暴雨历时短，强度大，一般降雨历时一至两天，超过三天以上很少出现，暴雨

3、中心多在栾川、陶湾。伊河洪水为暴雨所形成，受降雨特性影响，洪水过程陡涨陡落，洪水多发生在 710月份，特大洪水发生在78月份。流域内水系和站网分布见下图。（二）流域内水系和站网分布：四、采用资料(一) 编制方案采用的资料有：1流域出口断面逐时流量；2流域内雨量站逐日降水量；3流域内雨量站逐时降水量；4实测蒸发皿日蒸发量。五、产流方案的编制各站累计雨量摘录表日期时间栾川站年月日起迄PP19647269163.1 3.1161811.0 14.118206.4 20.520225.7 26.2272243.4 29.6467.0 36.66814.6 51.28168.9 60.129168:40
