The inflow hydrograph readings for a stream reach are given
below for which the Muskingum coefficients of K = 42 hr and x
= 0.25 apply. 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.
