For a 1.5 km² reservoir whose area does not vary with depth. The water elevation-discharge relationship at the spillway is approximated by the following function:
Q = 100(H - 5) for H>5m
Q = 0 for H <= 5m
where H is water level measured from the bottom of the reservoir, Q is discharge in ems (25 pts + 10 pt bonus)
2a) Sketch the storage-discharge relationship for the reservoir (12 pts)
