Construct a UH from the hydrograph depicted in Figure 3.12 and given in Table 3.18 for a 2-hour rainfall. The catchment area is 4.5 km². Use the constant value separation and construct a hydrograph representing the following complex rain pattern. The given values represent the excess rainfall depth (cm) in 2 hours.
