Problem VI: The 1-hr UH for a watershed is given in Table 1. The watershed is drained into a reservoir with a discharge- storage relationship of Q. = 0.00025S, where Q. (in mÂș sl) is the discharge, and S (in m?) is the storage. The watershed receives a 2-hr storm that generates 5 and 10 mm excess rainfall in the first and second hour, respectively. -- 1 t 1(1) Determine and plot the inflow hydrograph from the storm using the UH method -=; t (2) Determine and plot the outflow hydrograph from the storm using the Modified Puls method -- 1 t (3) Convert the 1-hr UH into the corresponding 2-hr UH using the S-curve method, and Plot the UHs, S-curve, and shifted S-curve on a same graph Table 1.
