Question
Example 5. The inflow hydrograph readings for a stream reach are given below for which the
Muskingum coefficients of K = 36 hr and x = 0.15. Route the flood through the reach and
determine the outflow hydrograph. Also determine the reduction in peak and the time of peak of
outflow. Outflow at the beginning of the flood may be taken as the same as inflow.
