Randomized trial investigates flood wave changes in the Three Gorges Reservoir, suggesting new forecasting methods.

This research aims to understand how flood-wave propagation changes after reservoir impoundment.
Calibrated a 1D hydrodynamic model for the Three Gorges Reservoir.
Analyzed flood-wave propagation and travel time under various scenarios.
Evaluated wave celerity using a physically based framework.
Near-dam wave celerity increased to ∼19 m/s at high reservoir levels.
Mean flood travel time reduced from ∼39 hours pre-impoundment to ∼15 hours at water level 175 m.
The celerity formulation showed R² values of 0.61 and improved to 0.90 with pre-impoundment data.
