Multi-objective detention basin design in urban drainage systems - Tradeoff between risk and cost

This note incorporates some of the previous research results given by Loganathan et al. (1985) to construct bi-objective detention basin design models considering the trade-off between the cost of installing treatment-storage facilities and the risk of detention basin overflow (both steady-state and single-step transition). The trade-off information is useful in helping the decision-maker make appropriate decisions in detention basin design. The use of a multi-objective framework enlarges one's scope which would help in making realistic decisions.
