将对瑞典大坝和溢洪道设计洪水的估算提出一种新指南。其重点是针对那些危险性较大的水坝。其方法是根据流域面积大小、季节和海拨高程等因素将地区设计降水系列作修改后,应用较完整的水文模型求设计洪水。水库的运行规则也是指南的一个基本部分。通过将设计降水系列系统地插入到十年气候实测资料中,再将初始的积雪用统计的30年积雪代替后,可找到产洪因子的最危险组合。新指南可应用于单一水库系统也可用于水库群所组成的较复杂的水电系统。既可适用融雪洪水也可适用暴雨洪水,以及两者混合的洪水。为了研究所求洪水的频率和避免地区的不协调性,将计算洪水与实测洪水进行了广泛的比较,还进行了频率分析。
A new guideline will be put forward to estimate the design floods of the Swedish dam and spillway. The focus is on those more dangerous dams. The method is based on the size of the catchment area, the seasons and the altitude of the elevation and other factors will be made after the regional design of precipitation series, the more complete hydrological model for design floods. The operating rules of reservoirs are also an essential part of the guidelines. The most dangerous combination of flood factors can be found by systematically inserting the design precipitation series into the 10-year climate data and then replacing the initial snow cover with the statistical 30-year snow cover. The new guidelines can be applied to a single reservoir system can also be used for more complex reservoir system consisting of hydropower. Both snowmelt floods and torrential floods, as well as floods of both, can be applied. In order to study the frequency of floods and to avoid regional incompatibility, an extensive comparison between calculated and measured floods was carried out and a frequency analysis was also conducted.
