Community-Scale Beach Nourishment And Groin Construction Decisions Along Human-Modified Coasts : The Interplay Between Socioeconomics, Coordination, Tourism, And Shoreline Change, Arye Max Janoff

Theses, Dissertations and Culminating Projects

In response to coastal erosion driven by storms, sea-level rise, and local gradients in sediment supply, communities defend their homes and maintain beach recreation by widening beaches via soft engineering (i.e., beach nourishment) or hard engineering (i.e., groins). Past research has found that, at regional scales, the net effect of these interventions has in many cases not only counteracted historically observed beach erosion, but has reversed erosional trends, on average shifting shorelines seaward. While groins trap sediments locally at and upcoast of the structure relative to the direction of alongshore transport, however, they often have adverse downcoast impacts, resulting in …
