Event Title

Effects of Pacific Northwest Winter Storms on Nearshore Processes in Puget Sound

Presentation Abstract

Unlike the Gulf of Mexico and mid-Atlantic coasts that are at the risk of storm surges induced by tropical cyclones and hurricanes, the Pacific Northwest coasts are subject to the threat of severe winter storms that cause heavy snowfall and rainfall, high wind and coastal storm surge. Sea-level rise as a result of climate change and extreme high tide can exacerbate the level of impacts of storm surge induced by winter storms in the Pacific Northwest coastal region, especially in the nearshore intertidal areas. This paper presents a modeling study of storm surge induced by winter storms and the impacts of coastal inundation on nearshore processes in the shallow estuaries and bays in Puget Sound using a coastal ocean model of Salish Sea and meteorological forcing from NOAA NCEP operational products. Storm surges in Puget Sound are simulated for selected winter storms and compared to NOAA real-time tide gages. Combined effects of future sea-level rise and storm surge on the nearshore hydrodynamics are also investigated with sensitivity modeling analysis.
