WATER RESOURCES ENGINEERING A 6-hour storm event occured in the study basin. You were able to measure precipitiation and infiltration data, but not streamflow. Using the precipitation and and infiltration data and the unit hydrograph, estimate the total streamflow during and after this storm event. Calculate stream flow for each time step until the total streamflow is equal to the baseflow of 35 m3/s. Please refer to attached images of data tables:
Question 3 The horizontal layout of foul sewer network is shown in Figure Question 3. The sewer network comprised of four sewers starting from MH1 to MH4.
