Implementing Flood-Resistant Design Strategies in Coastal Regions

This systematic review synthesizes findings from 85 articles to examine flood-resistant design strategies in coastal regions, emphasizing an integrated approach that combines traditional engineering solutions, nature-based strategies, green infrastructure, adaptive design, and predictive modeling. The review identifies a continuing reliance on engineered defenses, such as seawalls and automated floodgates, which have proven effective but are limited in addressing the escalating impact of climate change. Findings highlight the growing importance of nature-based solutions—wetlands, mangroves, and coral reefs—that not only mitigate flood risks but also enhance biodiversity and long-term sustainability. Green infrastructure, including permeable pavements and rain gardens, emerges as a valuable urban solution, although it faces implementation challenges in densely populated areas. The integration of predictive modeling and real-time data is transforming flood management by enabling proactive and adaptive responses, though these technologies remain financially inaccessible for many regions. Comparative analysis underscores that flood-resilient design is highly context-dependent, with successful practices varying based on local geography, resources, and socio-economic factors. This review concludes that future flood-resilient infrastructure must prioritize adaptable, sustainable, and region-specific solutions, highlighting the need for cross-disciplinary collaboration and continued policy support to enhance flood resilience and protect vulnerable coastal communities against the effects of climate change.
