hydrographs
Water level plots
Hydrographs are graphs showing how water flow or level changes over time at a specific point, typically in a river or stream.
Engineers and hydrologists use them to track flooding, plan drainage systems, and manage water resources.
A storm hydrograph plots the surge in river discharge following rainfall: The hydrograph showed peak flow twelve hours after the storm.
