6.2. The design storm of a watershed has the depths of rainfall of 4.9 and 3.9cm for the consecutive Ihr periods. The Ihr UH can be approximated by a triangle of base 6hr with a peak of 50 m³/s occurring after 2hr from the beginning. Compute the flood hydrograph assuming an average loss rate (D-index) of 9mm/hr and constant base flow of 10 m³/s. What is the area of the watershed? Ans. (10, 110, 285, 310, 222.5, 135, 47.5, 10), A=54Km²

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.
