Abstract: The Coastal Engineering Research Center of the US Army Engineer Waterways Experiment Station (WES) was requested by the US Army Engineer Division, Pacific Ocean (POD) to conduct a Typhoon Water Surface Analysis for the Flood Insurance Study of Saipan, Commonwealth of the Northern Mariana Islands. A comprehensive investigation to determine the frequency of occurrence of typhoon-induced flood elevations for the west coast of Saipan was performed. Since Saipan is located within the region subjected to typhoons similar to those considered in a previous stage-frequency analysis for Agana Bay, Guam, the synthetic typhoon ensemble used in that study was utilized in this investigation. The surge time- histories of t he storms were computed using the WES Implicit Flooding Model (WIFM). Deepwater wave conditions associated with each storm were calculated using a wave hindcast model. Predicted still water levels (swl) were calculated by combining surge and astronomical tide time- histories, and the ponding water levels caused by deepwater wave breaking on and over the reef. Wave setup for each storm was estimated using procedures presented in the Shore Protection Manual (SPM 1984). Stage-frequency relationships were established using the probability of occurrence of each storm event in the ensemble and the maximum swl generated by the storm.
