Travel time is the duration it takes for water to move from one point to another within a hydrological system, typically measured from the point of rainfall or runoff to a specific downstream location. This concept is crucial for understanding how quickly stormwater or floodwater reaches a given area, influencing both flood management strategies and hydrological modeling techniques. It connects with time of concentration, channel routing methods, and flood routing applications, providing insights into water movement and its impacts on hydrology.
