Question

The stage-discharge relation in a river during the passage of flood is measured. If $q_f$ is the discharge at the same stage when water surface is falling and $q_r$ is the discharge at the same stage when water surface is rising, then

• A. $q_f=q_r$
• B. $q_f<q_r$
• C. $q_f>q_r$
• D. $\frac{q_f}{q_r}=\text{constant for all stages}$

Answer 1

The correct option is B $q_f<q_r$


Hence option (b) is correct
