each on a basin are given below. The area of the basin is (4444) km2.
Assuming a constant base flow of 8.5 m3/s and ϕ-index of 0.25 cm/hour, derive a 6 hour
unit hydrograph.

The Muskingum method of flood routing has been chosen to forecast the movement ofa flood wave from a point 30 km upstream of a center of population. Engineers havepreviously estimated the Muskingum K and X parameters for this reach to be 10 hoursand 0.15 respectively.If the upstream flood was measured every 6 hours starting at 09:00 hours and the flowswere recorded as 25, 35, 50, 80, 140, 130, 90, 80, 50, 30 and 25 m3/s for the first 60hours and...

4-23. Determine the unit hydrograph ordinates for the Isosceles River with the stream flow data shown in Figure P-4-23 on page 192. The basin area is 14.40 km', and the unit duration of the storm is 1 hour. For ease of com- putation, locate ordinates at hourly intervals, that is, 1500, 1600, and 1700 hours. Note that the time is military time; that is, 1500 h 3 PM, 2000 h 8 PM, etc.
