Multiple choice

A flood wave with a known inflow hydrograph is routed through a large reservoir. The outflow hydrograph will have

  1. attenuated peak with reduced time-base

  2. attenuated peak with increased time-base

  3. increased peak with increased time-base

  4. increased peak with reduced time-base

B Correct answer
Explanation

 Main function of any reservoir in the flood routing is to reduce the peak and increase the time base so that there will be less damage on the downstream of flow.
