The Muskingum method of flood routing has been chosen to forecast the movement of a flood wave from a point 30 km upstream of a center of population. Engineers have previously estimated the Muskingum K and X parameters for this reach to be 10 hours and 0.15 respectively. If the upstream flood was measured every 6 hours starting at 09:00 hours and the flows were recorded as 25, 35, 50, 80, 140, 130, 90, 80, 50, 30 and 25 m^3/s for the first 60 hours and 25m^3/s thereafter then estimate the peak flow at the town and the time at which the peak flow will occur .
