AN INTEGRATED APPROACH TO ASSESS LEE SIDE EROSION IN RUBBLE MOUND GROIN SYSTEMS: A CASE STUDY
Abstract
Coastal erosion along Egypt's Northern Mediterranean coast presents a persistent challenge, particularly near the Kitchener Drainage, where human activities, such as infrastructure development and agriculture, have intensified shoreline retreat. Groynes have been widely used to stabilize the coastline by trapping sediment on the updrift side. However, their application has induced significant downdrift erosion, leading to sediment depletion, beach narrowing, and alterations in the shoreline profile.
This study aims to assess the long term effects of groyne construction in the Baltim region between 2007 and 2020, with a focus on shoreline evolution and downdrift erosion. Numerical modeling was conducted using the one-line model LITPACK, incorporating 31 years of wave data (1993–2023) from the Copernicus Marine Service and bathymetric surveys performed by Archimarine in 2020. Historical shoreline positions were derived from satellite imagery and field measurements to evaluate morphological changes. A brief discussion on mitigation measures and future studies is mentioned.
The LITPACK one line model successfully simulated shoreline evolution, capturing 20m per year erosion rates east of Kitchener Drainage from 2007 to 2013, with model standard deviation of 7m. The model also accounted for the 16 groynes constructed in 2020, where maximum downdrift erosion reached 195 meters, with 100,000 m³/year of sediment loss near the final groyne. The modeling results confirm that continued groyne extensions have not fully mitigated erosion but have shifted the problem further eastward.
