Abstract
Within the framework of safeguarding Egypt’s coastal lowlands, which face escalating susceptibility to both climate change and human interventions, this study aims to provide a comprehensive analysis of sediment transport dynamics and their implications, with Damietta serving as a case study. To achieve this, a thorough review of the existing literature on sediment transport dynamics was conducted. MIKE21 Shoreline Morphology (MIKE21 SM) model was employed to simulate longshore sediment transport (LST) dynamics both before and after the construction of Damietta Port (DP). Analysis of the model output revealed that the model underestimated the influence of waves, primarily originating from the Northwest, on shaping the LST pattern. The results indicate that the construction of DP led to a reduction in average gross longshore sediment transport (GLST) and average net longshore sediment transport (NLST) by 18%, decreasing from 1.1 to 0.9 106 x m3/year, and 42%, decreasing from 0.73 to 0.42 x 106 m3/year, respectively. Additionally, the average monthly GLST and NLST reductions were 17% and 37%, respectively, compared to pre-construction conditions. Consequently, this research underscores the importance of continuous monitoring of sediment transport to ensure shoreline stability and protect surrounding ecological systems. This recommendation is vital for managing and mitigating the impacts of ongoing and future coastal interventions.
