| 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 highway storm 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 stations and 5 to 60 minute data of 13 raingage stations of USDA Agricultural Research service were analyzed to provide the statistical values of the hyetograph parameters for the United States. Volume I is the executive summary of the project report. It briefly describes the background and objectives of the research project, the methodology and procedure of the first-moment triangular design hyetograph method, and results of statistical analysis of the rainfall data. |
