| Summary: | Over the years, researchers proposed different methods for flood frequency analysis. Research emphasizing statistical analysis is possible where enough gaged data is available. But often gaged data is not available. Hydrologic analysis tools, ie rainfall-runoff models, are used in these types of situations. The accuracy of rainfall-runoff modeling depends on proper simulation of the precipitation event. This research concentrates on the precipitation event of rainfall-runoff modeling and how it affects the flood frequency analysis. A method called Multiple Discrete Event Simulation was comprehensively analyzed. It was then compared with other techniques of flood frequency analysis. The other techniques that were chosen in these comparisons mainly focused on different methods to compute design storms. Sensitivity analysis on different design storm techniques was performed to get a better understanding of the methods. Flood frequency analysis by rational method and regression equations by the USGS were also included in this research. The analyses from these different methods were then compared with gaged data to find their accuracy. The results indicate that the MDES method can produce better results with adequate data available. |
