摘要
水库洪水预报方案构架工作是提高水库洪水预报预警能力,做好中型水库安全运行一项重要的工作流程,文章以皖西南某中型水库为研究标的,以产汇流形成原理为基础,在收集大量的历史资料分析基础上,进行水库洪水预报方案构架。构架结果显示:水库主要预报因子,径流深、入库洪峰流量均达到乙级方案等级,将构架好的方案用于实测洪水预报中,各水文预报因子也达到精度合格标准。
The framework of reservoir flood forecasting scheme is an important workflow to improve the ability of reservoir flood forecasting and early warning and do a good job in the safe operation of medium-sized reservoirs. This paper takes a medium-sized reservoir in Southwest Anhui as the research object, based on the formation principle of production and confluence, and carries out the framework of reservoir flood forecasting scheme on the basis of collecting a large number of historical data analysis. The framework results show that the main prediction factors of the reservoir, runoff depth and inflow peak flow all reach the level of class B scheme.When the framework scheme is used in the measured flood prediction, each hydrological prediction factor also meets the accuracy standard.
