$9.$ The inflow hydrograph into a stream reach and the corresponding outflow hydrograph are as given below. The ordinates of a $6-$h unit hydrograph are given.

$($a$)$ Determine the values of $\backslash ($ K $\backslash )$ and $\backslash ($ x $\backslash )$ for the reach.

$[$Ans: $\backslash ($ K$=24\mathrm{.}92\backslash$mathrm$\{$~h$\}$ ; x$=0\mathrm{.}2]\backslash )$

$($b$)$ By using the values of $\backslash ($ K $\backslash )$ and $\backslash ($ x $\backslash ),$ route the inflow hydrograph and obtain the outflow hydrograph. Compare the outflow hydrograph obtained from routing and actual outflow hydrograph by plotting them in same graph.
