Tracking the impact of surge barriers on storm sediment transport pathways

Project description

Promoting sustainable operation of surge barriers

Coastal regions are facing increased flood risks due to climate change, putting many people in danger. To protect them, more storm surge barriers are being constructed and closed during storms. However, these barriers can disrupt sediment transport in estuaries, threatening their stability. With the support of the Marie Skłodowska-Curie Actions programme, the StormTRACK project will assess the impact of surge barriers on sediment transport pathways during storms in estuaries, promoting their sustainable operation. The project will develop tools to simulate the movement of sand and mud particles at local and regional scales, validating these simulations using remote sensing images of sediment plumes. Its goal is to understand how surge barriers influence sediment transport in tide- and wave-dominated estuaries under various storm scenarios.

Objective

Low-lying coastal regions are facing a severe increase in flood risk as a consequence of climate change, placing a tenth of the world’s population under growing social and financial pressure. To protect these areas from flooding, more storm surge barriers are constructed in estuaries, and the closure of existing barriers during storm events is becoming more frequent. While these measures are necessary to keep coastal communities safe, closing a surge barrier can significantly alter the way storms transport sediments across an estuary. As such alterations can threaten the morphodynamic and ecological equilibrium of these systems with consequences for their long-term stability, understanding how to minimize the impact of surge barriers on estuary storm sediment transport dynamics is necessary. With StormTRACK, I aim to inform sustainable surge barrier operation by conducting the first assessment of surge barrier impact on storm sediment transport pathways in estuaries. To understand how storms transport sediments between different areas of an estuary and how surge barrier closure alters such dynamics, I will develop tools that will allow me to simulate the movement of sand and mud particles in coastal settings at local-to-regional scale and to validate such simulations through remote sensing images of sediment plumes. I will then employ these tools to investigate how surge barriers affect storm sediment transport pathways across tide and wave dominated estuaries for a variety of storm and surge barrier operation scenarios. Implemented at Caltech and TU Delft, StormTRACK will allow me to diversify my competences and skills, through advanced and interdisciplinary training, while strengthening my international and inter-sectoral network. Ultimately, I will be able to provide new fundamental knowledge about the interplay between surge barriers and storm sediments across estuaries and help promote sustainable estuary management across and beyond Europe.
