Recent research conducted by Zeineb Kassouk from the National Agronomic Institute of Tunisia has unveiled significant insights into the coastal evolution of Northern Tunisia, a region that is increasingly vulnerable to the impacts of climate change. Published in the journal ‘Remote Sensing’, this study leverages time-series satellite data to analyze the shoreline changes and geomorphological processes affecting the coastline between Cape Serrat and Kef Abbed over a span of nearly four decades.
The findings are particularly crucial for the construction sector, which often operates in coastal environments. As rising sea levels and increased erosion threaten infrastructure, understanding these dynamics becomes essential for sustainable development. “Our study shows that approximately 65% of the shoreline is under steady erosion, particularly near tombolo areas, which poses risks for any construction projects in proximity,” Kassouk stated. This highlights the need for developers to consider coastal management strategies that account for ongoing environmental changes.
Utilizing Landsat imagery from 1985 to 2019 and Google Earth satellite data from 2007 to 2023, the research employed the Digital Shoreline Analysis System (DSAS) to quantify shoreline movements, revealing a total net shoreline movement of -15 meters in the study area. Erosion rates reached alarming figures, with some locations experiencing up to -8.31 meters per year. This kind of data is invaluable for construction firms, as it allows them to make informed decisions regarding site selection and the design of resilient structures.
Moreover, the study identified distinct seasonal variations in shoreline dynamics, with maximum erosion occurring in winter and significant accretion in spring. “Understanding these seasonal patterns can help construction companies time their projects more effectively, minimizing risks associated with severe weather conditions,” Kassouk noted. This insight allows for strategic planning that can enhance the durability and longevity of coastal infrastructure.
The research also sheds light on the role of human activities, such as dam construction and urban development, in exacerbating coastal erosion. As the construction sector continues to expand in coastal regions, these findings underscore the importance of integrating environmental considerations into development plans. By doing so, companies can mitigate potential damage and align their projects with sustainable practices.
Kassouk’s work not only contributes to the scientific understanding of coastal dynamics but also serves as a critical resource for policymakers and construction professionals. “The methodology we employed can be adapted to other regions, providing a framework for assessing coastal changes and informing effective management strategies,” she emphasized. This adaptability points to a future where construction and environmental stewardship can coexist, fostering resilience in coastal communities.
As the construction industry grapples with the realities of climate change, research like Kassouk’s will be pivotal in shaping how projects are planned and executed along vulnerable coastlines. The comprehensive dataset generated through this study offers a foundation for future developments, enabling stakeholders to visualize and prepare for the impacts of sea-level rise in the southern Mediterranean region.
