Sea Level Rise and Recession
In this study, new analytical solutions are developed based on the convolution method to describe beach-profile response to sea water level change. Detailed, high-quality data sets obtained after the 2011 Tohoku Earthquake and Tsunami, including wave climate, beach profiles surveyed every 6 months, and bed level change due to tectonic movementwere used to validate the model. Bed level change is inversely related to the SLR process and the data provide a unique opportunity to evaluate the EBP concept. The model results are able to reproduce the observed beach retreat as a function of time using the proper SLR forcing.
