Human modifications in estuaries intensify tides, outpacing sea-level rise effects

The study uses hydrodynamic modeling and long-term tide-gauge data to demonstrate how human modifications—such as dredging and dam construction—alter tidal propagation. Scientific analysis confirms that these changes often exceed the effects of sea-level rise, necessitating a rethinking of coastal resilience strategies.
The altered tides in estuaries are not merely a consequence of climate change but a result of centuries of human intervention, including colonial infrastructure and modern engineering.
Indigenous knowledge systems offer alternative models of coexistence with tidal systems, while historical land-use data reveals the long-term consequences of estuary modification. Cross-culturally, estuaries are often viewed as living entities, and their degradation reflects broader ecological and social imbalances. Future modeling must integrate these diverse perspectives to develop adaptive strategies that restore ecological integrity and empower marginalized communities. By bridging scientific, historical, and Indigenous knowledge, we can move toward estuary management that is both resilient and just.
