“…Then the subcatchment is drained through the stormwater network. The rainfall events include 2-h design rainfall events with a Chicago hyetograph [53] and 6-h rainfall events with an actual rainfall profile. Different design storms will give the additional insight in the system behavior, helping to analyze the operation of the system when suffered different rainfall patterns.…”

“…Furthermore, storage tank provision is used as another adaptation measure for the tree drainage systems to reduce the flood volume. The cost function for tank is adapted from Tao et al (2014) [53] as below C = 2.195 × 10 4 × Volume 0.69 (6) where C is the cost of the tank, Yuan; and Volume is the provided volume of the storage tank, m 3 .…”

Vulnerability analysis of urban drainage networks plays an important role in urban flood management. This study analyzes and compares the vulnerability of tree and loop systems under various rainfall events to structural failure represented by pipe blockage. Different pipe blockage scenarios, in which one of the pipes in an urban drainage network is assumed to be blocked individually, are constructed and their impacts on the network are simulated under different storm events. Furthermore, a vulnerability index is defined to measure the vulnerability of the drainage systems before and after the implementation of adaptation measures. The results obtained indicate that the tree systems have a relatively larger proportion of critical hydraulic pipes than the loop systems, thus the vulnerability of tree systems is substantially greater than that of the loop systems. Furthermore, the vulnerability index of tree systems is reduced after they are converted into a loop system with the implementation of adaptation measures. This paper provides an insight into the differences in the vulnerability of tree and loop systems, and provides more evidence for development of adaptation measures (e.g., tanks) to reduce urban flooding.

“…Non-dominated sorting genetic algorithm II which is proposed by Deb et al (2002) is the most famous multiobjective optimization algorithm, which is widely used for generating the Pareto frontier (that is a set of solutions which would represent the best trade-off among the objectives) and satisfying both goals of Pareto multiobjective optimization (Tao et al 2014;Erfani et al 2013). Fast non-dominated sorting procedure, fast crowded distance estimation procedure, and simple crowded comparison operator are the special characteristics of NSGA-II (Deb et al 2002).…”

In this study, a multi-objective method for allocating the number and configuration of an air quality monitoring network based on non-dominated sorting genetic algorithm II has been presented. The multiple cell approach based on the solution of an Eulerian Model built on K-theory was used to predict the dispersion of emitted pollutants (SO 2 , CO, NO x ) from different emission sources. The multi-objective optimization method proposed in this study utilized two objectives: (1) maximum coverage area with respect to continuity of covered area and minimum overlap among coverage areas and (2) detection of violations over ambient standards. The concept of sphere of influence was used to determine the spatial area coverage of the monitoring station, and a weighing function was employed to measure the capability of a designed network to detect violations of air quality standards. The results show that three stations are suitable for the study region with coverage efficiency of 80 %. Analyzing the effect of cutoff correlation coefficient r c shows that, when the r c increases, although the coverage area decreases, the covered region will be well represented and overlap region will decrease.

Poor drainage of urban storm water can lead to urban inundation which presents a risk to people and property. Previous research has presented various measures to prevent and reduce urban flooding and these measures can be classified into costly but effective structural measures, and economical but less effective non-structural measures. This study suggests a new approach to reduce urban flooding by combining structural and non-structural measures in a target watershed in Seoul, South Korea. Inlet design modification in a detention reservoir (Decentralized Reservoir, DR) is examined in conjunction with combined inlet/outlet management for the DR. Monitoring nodes used to control DR inlet/outlet operations are selected by locating the first flooding node, maximum flooding node and DR inlet node. This new approach demonstrates outstanding flood volume reduction for historical flooding events that occurred in Seoul during 2010 and 2011. Flood volumes during the 2010 event using the combined inlet/outlet operation in the DR were between 1656 m 3 and 1815 m 3 compared to a flood volume of 6617 m 3 using current DR operation. Finally, the suggested operating level for the DR based on the best hydraulic section, system resilience index, and local regulations is 1.2 m.
