Shape Optimization for the Mitigation of Coastal Erosion via Porous Shallow Water Equations

Luka Schlegel,
Volker Schulz

Abstract: Coastal erosion describes the displacement of land caused by destructive sea waves, currents or tides. Major efforts have been made to mitigate these effects using groins, breakwaters and various other structures. We address this problem by applying shape optimization techniques on the obstacles. We model the propagation of waves towards the coastline using two-dimensional viscous and porous Shallow Water Equations. The obstacle's shape, which is assumed to be permeable, is optimized over an appropriate cost f… Show more
