Abstract [en]

Coastal flooding on the Pacific Coast of the United States typically results from the joint occurrence of relatively high water levels and large waves, which are partially correlated. This paper evaluates three approaches to address the joint probability of water levels and waves (flood forcing events) in estimating coastal flood levels (responses) with a 100-year return period. The event approach involves selecting extreme events that are expected to force a response that approximates or exceeds the 100-year flood response. The two response approaches determine the response probability from a calculated response data set. The approaches were applied to a sheltered waters site to inform the development and implementation of the United States Federal Emergency Management Agency's guidelines for mapping coastal flood hazards on the Pacific Coast. Both event and response approaches can provide adequate results, but each requires varying levels of judgment and has advantages and disadvantages. A hybrid between event and response approaches is identified as a balance of accuracy and efficiency in coastal flood studies.
