- Abstract
- In the context of urbanization and waterworks construction, detention basins located in upstream tributaries have become one of the most-effective technical solutions for downstream flood reduction. This technical note proposes a new optimal approach for determining the most-effective design combination of detention basins (in terms of their sizes and locations) in a watershed utilizing linear reservoir theory. The optimal detention basin is obtained by minimizing the deviation of downstream peak discharge from river capacity discharge. With the presence of a detention basin in an upstream river, the flood peak downstream decreases by 33%, corresponding to two scenarios of rainfall duration with a return period T=100 years. The storage volume estimation of the optimal detention reservoir proposed in the present paper demonstrates the high applicability of this optimization approach.
