| Abstract |
This report investigates the capabilities of XBeach for long term profile development. Typically cross-shore profile models are just applied to model storm impacts. Within the study an attempt is made to go beyond these common applications by focusing on medium (1 year) to long term applications (10 years). Potential applications include the evaluation of long term profile stability, such as in Knokke, the evolution of a beach or shoreface nourishment, and ultimately the evaluation of coastal retreat due to sea level rise. To this end, firstly the physical processes controlling the profile evolution are identified, secondly the implementation of these processes in XBeach and in Delft3D is reviewed, and finally the capabilities of XBeach are evaluated based on modelling exercises. The study shows promising results and highlights the current bottlenecks to be addressed. |
