How do you define flood routing?

Flood routing is the process of predicting the movement and timing of floodwaters as they travel through a river system or watershed. It involves analyzing the inflow and outflow of water, the terrain, and various hydraulic factors to estimate how floods will propagate downstream. This practice is crucial for flood management, helping to inform decisions about flood control measures, emergency response, and infrastructure planning. Ultimately, flood routing aids in mitigating the impacts of flooding on communities and ecosystems.
