Study of design storms in China

Abstract A study of design storms mainly involves the frequency analysis of point rainfall, depth-duration relationships, depth-area relationships and storm patterns. This paper discusses the application of some effective methods used in China, such as the full use of storm data (including data from field investigation), storm data regionalization, development of isoline maps of statistical parameters of different durations, study of the “fixed-point to fixed-area relationship” and evaluation of Probable Maximum Precipitation (PMP).
