To obtain synthetic unit hydrographs for stations in the G$$ksu basin where flow$-$precipitation measurements are not available, the values of $C_t$ and $C_p$ coefficients in the Snyder method are measured. The characteristics of $24-$hour unit hydrographs for stations with flow$-$precipitation measurements in the basin and basin characteristics are provided. Accordingly, determine the coefficients. $($tPR $=T_{PR}-0\mathrm{.}5t_0)$
