A watershed is divided into two sub-basins A and B. The surface runoff from sub-basin A enters a channel at point 1 and flows to point 2 where the runoff from sub-basin B is added to the hydrograph and the combined flow is then routed through a reservoir. a. Determine the discharge hydrograph from the reservoir assuming that the reservoir is initially empty (i.e. no baseflow). (Only plot up to hour 12). Also, provide ERH and SHG plots for each sub-basinb. What are the areas of sub-basins A and B in square miles?
