A Study on Boundary Conditions of Q3d-Febs-Fwi for Flow Analysis in River Mouths With Coexisting Flood Flows, Waves, and Tidal Fluctuations

Key Points

• The aim is to investigate boundary conditions for analyzing flow in river mouths with coexistence of flood flows, waves, and tidal fluctuations.
• Developed a joint analysis method Q3D-FEBS-FWI for flood flows and waves.
• Introduced wave generation techniques and energy dissipation zones based on coastal field methods.
• Focused on the large time-scale variations of flood flows and tidal levels relative to wave period in the energy dissipation zone.
• Conducted numerical simulations and computational reproductions of previous experiments on flow interactions.
• Demonstrated potential for analyzing flow in river mouths where flood flows, waves, and tidal fluctuations interact.
• Successfully modeled the influence of flood flows on wave dynamics and tidal variations.
