... Danube River can encounter incredibly high flows during extreme flood events, presenting a substantial danger to around 490,000 individuals. These flood mitigation measures incorporate the enhancement of existing flood control structures and the construction of new ones on both banks of the Danube River (Figure 10). The designated buffer zone along the Danube River is fixed at 0.5 meters above the stipulated floodwater level. ...

This paper presents the design concept and static stress analysis of a self-activated flood barrier, an innovative solution for flood defence in vulnerable areas such as urban centres, coastal regions, and riverbanks. The self-activated barrier is designed to respond autonomously to rising water levels without external power or human intervention, utilizing a buoyancy-driven mechanism that enables it to rise automatically as floodwaters approach critical levels. Designing a flood barrier involves a combination of scientific analysis, engineering design, construction, and community involvement. The design integrates a modular approach, allowing for scalability and adaptability to different geographic and infrastructural contexts. Static stress analysis was conducted on the barrier to evaluate its structural integrity under various flood conditions. The analysis focused on key components subjected to water pressure during deployment, ensuring the materials and structure could withstand the forces encountered during a flood event. Results from the analysis indicate that the barrier’s design is able to withstand the static load and the dynamic load that will occur under peak flood conditions. Furthermore, the material proposed for the inner barrier, which is Polyethylene terephthalate (PET) is lightweight yet durable and corrosion-resistant which will ensure long-term operational performance in harsh environments. Overall, the study demonstrates the effectiveness of the self-activated flood barrier in providing reliable, low-maintenance flood protection, with static stress analysis confirming its capability to endure extreme flood pressures.
