| Abstract | Recently developed improved methods for highway storm water drainage require information on the temporal distribution of rainfall (i.e., hyetograph) in addition to the average rain intensity. The triangular design hyetograph method is developed as a practical method to provide the local storm hyetograph for design of small highway drainage facilities. The method is based on the methods of moments, using and preserving the statistical mean of the first time moment of rainstorms. The method is proposed as a trade-off between theoretical sophistication and practical simplicity. A total of 293,946 rainstorms from the hourly precipitation data of 222 National Weather Service (NWS) stations and 5 to 60 minute data of 13 raingage stations of USDA Agricultural Research Service (ARS) were analyzed to provide the statistical values of the hyetograph parameters for the United States. The results of statistical analysis of the mean, standard deviation, and range of rainstorm parameters for each class of duration and depth range for each of the 235 stations are summarized in 3600 tables which are stored at the University of Illinois at Urbana-Champaign. Results of two sample stations, one each from the NWS and ARS stations, are presented in 84 tables in this Volume IV. |
