流域降雨资料合理性检查实例分析

水文资料主要包括流域降雨和径流资料,降雨资料作为水资源开发利用和防汛抗旱的重要基础数据,其资料精度与合理性审查始终是水文分析计算工作的重要前期工作。文章以2014年伊春河流域降雨资料为例,以单站检查和综合检查两个方面其资料进行分析,具体项目有单站降雨年内分配;月年总量;不同时段总量;降雨过程;雨洪过程对比等。分析结果表明流域当年降雨资料通过合理性检查相关要求,满足刊印存档和对外发布的标准。

Hydrological data mainly include watershed rainfall and runoff data, and rainfall data are an important, basic data forwater resources development, flood control and drought relief, so the examination of the accuracy and rationality of the data is alwaysan important preliminary task in hydrological analysis and calculation. Taking the rainfall data of Yichun River Basin in 2014 as anexemplar, the paper analyzes the data from two aspects of single station inspection and overall inspection, with the specific items be-ing monthly and annual total amount, total amount in different periods, rainfall process, comparison of rain flood processes, etc. Theanalysis results show that the rainfall data of the watershed in that year meet the standards of publication, archival and publicationthrough checking the rationality of the relevant requirements.
