This hydrograph shows how rainfall (top bars) and stream discharge (bottom area) changed over the course of the Boscastle flood event in 2004. The combination of both datasets on one chart makes it easy to see how rainfall influenced streamflow over time, helping identify patterns like peak discharge and runoff delay.
This format is commonly used in hydrology, but it’s also great for any situation where one event triggers a response over time – like traffic flow after a concert, or energy use during a heatwave.
