1.Based on 26 year self recording rainfall observation data from Fleissner Weather Station in Austria, by way of the analytical method of rainstorm frequency, the rainstorm amount with rainfall duration from 5 min to 24 h and recurrence period from 0.5 year to 100 year were calculated, the relationship between designed rainstorm amount and rainfall duration or recurrence period was also established in Graden Watershed.
根据奥地利伏拉斯勒(Fleissner)气象站26a的自记降雨观测资料,应用暴雨频率分析方法,计算了格拉顿(Graden)小流域降雨历时从5min至24h及重现期从0.5a至100a的暴雨量,得到了格拉顿流域设计暴雨量与降水历时和重现期的关系。收藏指正
