摘要
本文结合近年来大浪淀水库旱情发展趋势,采用典型年法、生活用水总量法、取水口设施高程分析法等确定了一系列有分析价值的水位,按照资料年限统计了各种水位的出现频次和重现期,结合现有资料绘制了理论频率曲线,与本文所计算的重现期进行对比,确定最为接近的水位作为大浪淀水库旱限水位。可为其他水库旱限水位的初步确定提供思路。
In this paper,combined with the development trend of drought in Dalangdian Reservoir in recent years,a series of water levels that are valuable for analysis are determined by using typical year method,total domestic water consumption method and elevation analysis of water intake facilities,etc.The occurrence frequency and recurrence period of various water levels are statistically analyzed according to the data length,and a theoretical frequency curve is drawn based on the existing data.A comparison is made between the calculated recurrence period and the closest water level is determined as the drought-limited water level of Dalangdian Reservoir.It can provide ideas for the preliminary determination of droughtlimited water levels in other reservoirs.
