Abstract:This research aims to enhance flood protection by designing and evaluating resilient dike systems and comparing their effectiveness and costs with traditional dike structures. The focus is on a crucial section of the Pleij dike, which protects the city of Westervoort from the Rhine and Ijssel rivers. The research begins with identifying the challenges in current dike designs and establishing the objectives. A comprehensive literature review is conducted to understand the mechanisms of dike failure and breaching processes. Innovative dike designs are proposed and modeled using D-Hydro software to simulate breach scenarios. The Schade en Slachtoffer Module (SSM2017) assesses these breach scenarios' direct damage and casualties. A comparative analysis of various dike designs focuses on breach characteristics, cumulative water discharge, damage extent, casualties, and construction costs. The results show that tough dike designs can significantly mitigate damage and improve flood resilience compared to traditional designs, as evidenced by reduced water discharge and lower casualty rates in simulations. A sensitivity analysis is conducted to ensure the robustness of the findings. The study concludes that integrating tough dike designs into future flood defense strategies is crucial for enhancing long-term resilience; however, further research is needed. The report provides recommendations for stakeholders on adopting these resilient designs to protect flood-prone areas better.
