Hydrographs

A hydrograph is a graph that shows how water flow in a river or stream changes over time. It typically displays the amount of water (discharge) on the vertical axis and time on the horizontal axis. Hydrographs help us understand how rainfall or other factors affect water levels, showing peaks during storms and drops during dry periods. They are useful for flood prediction, water management, and studying river behavior. By analyzing hydrographs, scientists and engineers can better plan for flood risks and manage water resources effectively.
