Short-term microbial community reassembly and sediment-driven water quality pulses following a managed weir opening in the Nakdong River

Key Points

• Microbial community shifts occurred shortly after the managed weir opening, affecting water quality.
• Water quality metrics showed significant fluctuations in chemical composition, particularly in nutrient levels.
• Observational analysis evaluated sediment-driven changes in water quality across the Nakdong River ecosystem.
• Findings highlight the importance of weir management on ecosystem health and water quality dynamics.
