Abstract
Coastal erosion threatens densely populated shorelines worldwide. At the Rosetta Promontory (Nile Delta), shoreline
retreat has accelerated since the construction of the Aswan High Dam due to reduced fluvial sediment supply. This case
study numerically evaluates shoreline response to six hard-protection scenarios along the eastern promontory,
combining groins and detached breakwaters, over a 20-year forecast (2022—2042). Offshore wave conditions were
transformed to nearshore hydrodynamics using MIKE21 spectral wave, and long-term shoreline evolution was simulated
with DHI-LITPACK.
