Event Title

Relationships Between Beach Sediment Characteristics and Foreshore Slope on Puget Sound Beaches

Presentation Abstract

Beaches throughout the Salish Sea are contained in a broad spectrum of geologic and geomorphic conditions. The majority of these beaches consist of mixed sand and gravel sediment compositions which were derived from extensive glacial deposits, and sorted by waves. The literature contains very little research into mixed grain size beaches and how the slope and character are controlled by wave energy. This poster contains data and findings from an initial investigation of beach sediment and topographic data collected from beach monitoring efforts around the Puget Sound in order to discern patterns between sediment composition and the profile and slope of a given beach. Data is available from both nourished and natural beaches Sediment grain size statistics were used to describe the sediment for comparison to physical beach parameters such as shape and slope.

With the number of bulkhead removal and beach restoration projects underway in the Salish Sea these data could prove to be invaluable to engineers and geologists in designing beach nourishment projects for restoration or soft shore protection. It is our hope that these data will allow for additional research to better understand and model wave interactions with mixed sand and gravel beaches in the Puget Sound.
