Question: Measured stream flow data during a storm event on Judith Creek produces a roughly triangular hydrograph shape. The peak occurs 3 hours into the storm

Measured stream flow data during a storm event on Judith Creek produces a roughly triangular hydrograph shape. The peak occurs 3 hours into the storm and measures 504 cfs. There is no base flow before the event, so the discharge starts at time zero, climbs to the peak in 3 hours, and recedes linearly back to zero in another 5 hours. The drainage area is 1,000 acres, and most of the runoff from the 2.5 inches of rainfall occurs during a 2-hour period. Sketch the storm hydrograph and determine the unit hydrograph. Is the unit hydrograph you developed a 1-hr, 2-hr, or 3-hr unit hydrograph?
