Hydrology

Subtopic: Flood routing, hydrological reservoir and channel routing

Question Statement:

In the Muskingum flood routing method, the coefficients are $C_0 = 0.10$ and $C_1 = 0.55$. The routing equation is $O_2 = C_0 I_2 + C_1 I_1 + C_2 O_1$. The value of coefficient $C_2$ is ________ (round off to 2 decimal places).

Answer Key:

0.35

Step-by-Step Solution & Explanation

The fundamental condition for the conservation of mass in Muskingum routing coefficients is: $C_0 + C_1 + C_2 = 1.0$ Given $C_0 = 0.10$ and $C_1 = 0.55$: $C_2 = 1.0 - (0.10 + 0.55) = 1.0 - 0.65 = 0.35$
