Abstract

In recent years, sedimentation and coastline erosion have occurred in the Kitchener Drain, where its outflow meets the Mediterranean Sea. Several measures have been taken to mitigate the impact of these problems. Excavation continues toward the drain's outlet, and there have been multiple stages of hard protection work, such as groins along the drain's eastern and western banks. What would happen if the working near the drain was kept, where accretion and erosion are most severe. The Coastal Modelling System (CMS) was used to find it out. The two-dimensional hydrodynamic circulation model known as the CMS is outfitted with modules for guiding CMS flow and CMS wave. To begin mitigating this effect, the initial year of the simulation was 2012 with adjusting the calibration parameters. To determine the most effective method of controlling exit sedimentation and erosion to the east and west, the study will consider every possible consequence. The three-part drain zone (Eastern, Western, and Outflow) necessitated the implementation of multiple hard and soft protection scenarios to ensure stability in the vicinity. The fourth scenario, thickening the bottom interval of the existing nine groins, was the most effective in maintaining a steady shoreline. Both the erosion in the western zone and the sedimentation at the drain outflow reduced, with the former falling from -133433 m3 to -109502 m3. Considering the impact of wave force on grain size, four more scenarios were evaluated with different d50 values to mitigate erosion induced by grains' mobility. With the third feeding scenario, the sediment volume at the exit increased from -10880-20 m3 to -19270 m3. Finally, the scenarios influenced preservation efforts by successfully preserving the stability of the land surrounding the drain.
