“…This approach has been commonly referred to as the "bathtub" method, or the "equilibrium" method (Gallien et al, 2011), and it has been improved in later studies by accounting for hydrologic connectivity (Poulter and Halpin, 2007;Poulter et al, 2008). Such a procedure is essentially a contouring process.…”

“…The above evaluation models have played an important role in the vulnerability analysis of water distribution systems, but there were a few studies for urban drainage systems [2,[32][33][34][35][36][37][38]. For example, Moderl et al (2009) developed the VulNetUD method, which is for GIS-based identification of vulnerable sites of urban drainage systems using hydrodynamic simulations undertaken using EPA SWMM [32].…”

Poulter et al (2008) presented an application of graph theoretic algorithms to efficiently investigate network properties relevant to the management of a large artificial drainage system in coastal North Carolina, USA [33]. Some studies focused on the structure or hydraulic conditions of a single pipe in order to make safety evaluation [39], though a higher order of failure is considered in few studies [40].…”

Vulnerability Analysis of Urban Drainage Systems: Tree vs. Loop Networks

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.

“…The interest in river channel network has been concentrated on analyzing its topological structure by descriptive measures, for example, discussing the relationship between river channel network morphometry and river reach hydrologic and geomorphic characteristics (Moussa, 2008), and exploring how river channel network structure imposes effects on ecological patterns, such as riverine habitat organization (Benda et al, 2004), fish assemblage structure (Hitt and Angermeier, 2008), and riparian vegetation distribution (Shaw and Cooper, 2008). However, combining structures of graphs and algorithms to find optimal network paths (Poulter et al, 2008) or predicting streamflow statistics with river channel network models (Young et al, 2000;Liu and Weller, 2008) have also been explored. The welldeveloped application of graphs and algorithms allows us to design an artificial river channel network to address risks of a single river reach by supplementing the removed connection in urban areas, where the real state of basin is one of highly fragmented and largely modified transfers (Graf, 2001).…”
