This study presents a comprehensive meta-analysis of 624 academic publications spanning five decades (1964–2025) to trace the environmental trajectory of the Nakdong River basin and its estuary. The findings reveal that the physico-hydrological environment underwent irreversible shifts following major structural interventions, namely the construction of the estuary barrage and eight multi-purpose weirs. These structures significantly altered flow velocities and sedimentation patterns, exacerbating water quality degradation. Recent research (post-2010s) highlights that the formation of stagnant water bodies, coupled with climate change, has increased the vulnerability of the estuarine ecosystem. While current partial gate openings show positive signs of ecological recovery, such as the migration of catadromous species, achieving full restoration requires setting quantifiable targets for indigenous freshwater fish recovery. Furthermore, engineering countermeasures-including footing protection (根固工) to prevent scouring and aeration systems to mitigate algal blooms-must be integrated. This study concludes that a paradigm shift toward Integrated Water Resources Management (IWRM) is essential to restore hydrological resilience and ensure sustainable ecosystem services in the Nakdong River.
