From the basin map of a given watershed, the following quantities are measured: L = 150km, L. 75km, and drainage area = 3500 km2. From the unit hydrograph derived for the watershed, the following are determined: tg = 12h, tpR = 34h, and peak discharge = 157.5 m³/s-cm. Determine the coefficients C; and C, for the synthetic unit hydrograph of the watershed.

Question
From the basin map of a given watershed, the following quantities are measured: L = 150km, L. = 75km, and drainage area = 3500 km2. From the unit hydrograph derived for the watershed, the following are determined: tR = 12h, tpR = 34h, and peak discharge = 157.5 m/s-cm. Determine the coefficients C; and C, for the synthetic unit hydrograph of the watershed. Compute the six – hour synthetic unit hydrograph of a watershed having a drainage area of 25O0km2 with L = 100km and L. = 50km. This watershed is a sub – drainage area of the watershed in the first problem.
