Reverse Flood Routing for Upstream Hydrograph Reconstruction: Methods, Challenges, and Future Directions—A State-of-the-Art Review
Flood forecasting often depends on upstream hydrographs that are unavailable, incomplete, or unreliable. Reverse Flood Routing (RFR) addresses this gap by reconstructing upstream inflows from downstream observations, yet its operational use remains limited by numerical instability, observational uncertainty, and the il...
