Tidal river flooding is driven by coastal development, climate‑induced sea‑level rise, and altered watershed management, not just tide‑river interaction

Recent high‑resolution coupled ocean‑river models quantify how tidal resonance and river discharge interact, revealing non‑linear amplification under certain flow regimes. Empirical data from satellite altimetry and gauge networks validate these mechanisms, providing a robust basis for predictive forecasting and scenario testing.
Tidal river flooding emerges from a nexus of climate‑driven sea‑level rise, historic water‑management choices, and contemporary land‑use pressures, a reality that scientific models alone cannot fully capture.
Indigenous and cross‑cultural practices demonstrate that flexible, relational stewardship can attenuate flood peaks, while historical analysis warns against the rigidity of engineered solutions. By integrating high‑resolution modelling with community‑driven monitoring, equitable policy reform, and nature‑based infrastructure, societies can transform flood risk from an inevitable disaster into a managed, regenerative process. Actors ranging from municipal planners and water authorities to Indigenous councils and climate NGOs must coordinate through integrated governance frameworks that embed both scientific rigor and lived experience.
