Multi-objective optimal layout of distributed storm-water detention
Tao, T.; Wang, J.; Xin, K. & Li, S.
Abstract
The determination of locations and sizes for
such a system is important in a drainage master plan or a
storm-water management system. However, the distribution
of detentions in the upstream and midstream is often
more dispersed using many combinations of volume scales.
This paper uses the non-dominated sorting genetic algorithm
combined with the Storm Water Management Model
to explore and calculate the optimal layout scheme for
decentralized rainwater detention. The purpose is to find a
design and planning method that can achieve the optimal
balance of decentralized detention considering the aspects
of flood disaster control, peak flow reduction, and investment
cost. The optimal results of Pareto in applied case
show that among the five most unfavourable nodes, the
detentions with different layout volumes and relatively
smaller size can control water logging from rainstorm. The
project cost is effectively reduced and the standard of the
return period of the regional rainwater system is enhanced
from 2 to 20 years.
