Algorithmic funnel‐and‐gate system design optimization

Abstract: [1] Funnel-and-gate systems (FGSs), which constitute a common variant of permeable reactive barriers used for in situ treatment of groundwater, pose particular challenges to the task of design optimization. Because of the complex interplay of funnels and gates, the evolutionary algorithms applied have to cope with multimodality, nonseparability, and nonlinearity of the optimization task. We analyze these features in a test case, introducing an objective function for design cost and constraints to account for p… Show more

“…The same models can also be utilized to investigate the value of data (subsequently called data worth) in existing monitoring networks and to design extended monitoring strategies that increase the reliability of model predictions. This technique, called optimal experimental design (OD), has found widespread application in the field of groundwater quality monitoring and remediation (e.g., Zhang et al ; Bürger et al ; Chadalavada and Datta ).…”

“…However, in the absence of a barrier, the distance from the source to a point where the permissible concentration of Zn reaches 5 mg/l was earlier found to be 100 m. Similarly the width of barrier (along the y direction) needed for a full plume capture is obtained as 16 m, which is also small when compared to the width obtained in the absence of a barrier. Later the total installation cost of a continuous permeable reactive barrier is obtained as €652,000 using the cost function of Bürger et al [16].…”

“…A wide variety of methods to date deal with one or a number of aspects of brownfield revitalization such as risk assessment (e.g., Carlon et al, 2008;Semenzin et al, 2006;Strenge and Chamberlain, 1995), policy analysis (e.g., Linkov et al, 2006), optimization of remediation (e.g., Ahlfeld et al, 1995;Bürger et al, 2007;Wang and McTernan, 2002), remediation cost assessment (e.g., Kaufman et al, 2005), general success factors for brownfield redevelopment (e.g., Lange and McNeil, 2004;Nijkamp et al, 2002), infrastructure redevelopment (Attoh-Okine and Gibbons, 2001), urban planning and site prioritization under budget constraints (e.g., AlvarezGuerra et al, 2009;Stevens et al, 2007) and mediation of negotiation (Sounderpandian et al, 2005).…”
