Like flood frequency analysis, individual rainfall event has a return period attached to it. Rainfall has two important attributes: depth and duration, hence rainfall frequency analysis involves the depthduration- frequency model (DDF). A DDF can be used to estimate design rainfall or to assess rarities of observed rainfall events.

Keywords: epth-duration-frequency, areal reduction factor, design storm profile
