Concept explainers

Unit Hydrograph

Hydrology is the science which deals with the study of water on the earth’s surface. The word Hydrograph is derived from the word hydro which means water. Hydrograph is basically a graph in which the discharge is plotted against the time interval at a specific point in a river or other channel. In a hydrograph, the discharge is plotted along the y-axis and time interval is plotted along the x-axis. Hydrograph is used to estimate the runoff. The variations in discharges with the change in time is shown by a hydrograph. It was revealed that the total discharge at an outlet increases with time by a kinematic wave model.
