但是,城市排水短历时设计暴雨、选样方法采用的是年多个样值。
Storm sampling method is often annual multisampling method in urban drainage engineering.
讨论了采用年多个样法选样时,城市短历时暴雨的指数分布的统计特征。
The statistical characteristics of exponential distribution of urban short-duration rainstorm are studied when the rainstorm series are chosen by annual multi-sampling method.
暴雨在短历时内产生较强的降雨,而且暴雨的间隔时间尺度越短平均雨强就越大。
Storm brings strong rainfall intensity in short duration, moreover, the shorter duration the average rainfall intensity is stronger.
发现雨季不同时期土体含水量差异较大,而且在不同时期激发泥石流的短历时雨强也不同。
