Systematic investigation of the hydrodynamic adaptive adjustment characteristics in the river network of the Pearl River Delta

Key Points

• To systematically investigate the hydrodynamic adaptive characteristics of the Pearl River Delta river network.
• Combined topological analysis and numerical simulation to examine the river network characteristics.
• Analyzed physical morphology and dynamic connectivity of the river network.
• Identified increases in branch channels and flow cross-sectional area as adaptive adjustments.
• Demonstrated that runoff dynamics drive structural reorganization of the river network under tidal cycles.
