Report

Number of participants	50

Applications of storm surge models in the US, the Philippines, Japan, and Taiwan were presented. Europe, the Americas, and Japan each use different models for weather forecast and reanalysis, so the necessity to compare results of these different models and the effect of differences on storm surge and wave prediction and hindcast came to light. The need for phase-averaged vs. phase-resolving wave models to simulate storm surge and wave phenomena striking cities near coral reefs and wetlands during typhoons and hurricanes were debated, applied to the recent examples of Typhoon Haiyan in the Philippines and Hurricane Sandy in the US. The study of tidal bores, which occur regularly and are thus easier to measure than unpredictable tsunamis or hurricanes, was discussed as a way to better understand the physics of destructive bores and plan countermeasures to such events. The tradeoffs between 2-dimensional and 3-dimensional models were also debated, including bottom stress parameterization, run time, and dispersion. Participants also discussed methods to predict, survey, and mitigate hurricane damage to buildings, infrastructure, and utilities. Furthermore, sediment deposits were presented as a proxy for investigating prehistoric storm surge inundation extent, but also as a source of turbidity when entrained into terrestrial rivers and the coastal ocean.

Outline

Typhoon Haiyan caused heavy damage due to both expected storm surge and unexpected large wave phenomena. Reliable prediction and assessment of storm hazards is essential to reducing the vulnerability of coastal communities subject to hurricanes and typhoons. The cutting edge of wave modeling and storm damage/risk assessment will be debated in this workshop.
