The effect of mass transfer limitations on the optimization of groundwater remediation strategies was investigated by linking a ground water simulation model into a Genetic Algorithm (GA) optimization technique. Runs were performed to minimize pumping and treatment costs associated with pumping rates and air stripping tower performance. Remediation designs for a hypothetical aquifer, contaminated with trichloroethylene (TCE), assuming either linear equilibrium or two-site kinetic sorption, are compared. Results indicate that the equilibrium sorption assumption for groundwater remediation optimization may result in over-estimation of the clean up rate and in sub-optimal designs.

Impact of physical and chemical heterogeneities on optimal remediation design and costs
Aksoy, Ayşegül (null; 2001-01-24)
The impact of physical and chemical aquifer heterogeneities on optimal remediation design and costs is investigated by linking a genetic algorithm optimization library with a contaminant transport simulation model. Various levels of physical and chemical (sorption) aquifer heterogeneities are examined. In the first level, heterogeneity is limited to the hydraulic conductivity (K) field. Then systems with heterogeneity in both K and the distribution coefficient (Kd) are considered. The final level of heterog...
Binalarda Güneş Kontrol Yöntemlerinin Optimizasyon Temelli Performans Değerlendirilmesi
Gürsel Dino, İpek (2017-01-01)
Bu çalışmada, binalarda farklı güneş kontrol yöntemlerinin karşıtlaştırmalı analizini, bir genetik optimizasyon algoritması ile destekleyen bir tasarım aracı ve yöntem, önerilmektedir. Çalışmada ilk olarak farklı cam alternatifleri ve sıklıkla kullanılan bazı standart gölgeleme yöntemlerinin oluşturduğu sekiz senaryo geliştirilmiştir. Ardından bu senaryolar, örnek bir bina tasarımı üstünde uygulanarak genetik optimizasyon algoritması uygulanmıştır. Algoritma, pencere büyüklüklerini ve gölgelik boyut paramet...
Impacts of physical and chemical heterogeneities on aquifer remediation design
Aksoy, Ayşegül (American Society of Civil Engineers (ASCE), 2004-07-01)
The impacts of physical and chemical aquifer heterogeneities on optimal remediation design, costs, and time to compliance are investigated by linking a genetic algorithm with a contaminant transport simulation model. Physical and chemical aquifer heterogeneities were grouped into three levels as follows: (1) hydraulic conductivity (K) heterogeneity only; (2) combined heterogeneity of K and the distribution coefficient (Kd); and (3) combined heterogeneity of K, Kd, and the mass transfer rate (α). Various deg...
The use of the SPT-based seismic soil liquefaction triggering evaluation methodology in engineering hazard assessments
Çetin, Kemal Önder; Kayen, Robert E.; Moss, Robb E. S.; Bilge, Habib Tolga; Ilgaç, Makbule (2018-01-01)
Probabilistic and deterministic seismic soil liquefaction triggering methodologies are proposed in Cetin et al. [1]. This manuscript: i) presents the protocols, which need to be followed for the correct use of this methodology for forward engineering (design) assessments, ii) guides the engineers through the procedure, and iii) discusses the "tricks" alongside the protocol. An illustrative soil profile shaken by a scenario earthquake is presented, through which consistent estimations of representative SPT b...
The Effects of Implementing Different Ground-motionLogic-tree Frameworks on Seismic Risk Assessment
Ay, Bekir Özer (null; 2018-06-21)
This study investigates the link between probabilistic seismic hazard assessment and corresponding loss estimations by using different ground-motion logic-tree frameworks from reliable large scale seismic hazard projects as well as the logic-tree framework established in this study. The predictive models selected for these logic trees are expected to represent the center, body and range of ground-motion intensity measure estimates. Regarding with the hazard component of risk assessment, the ground motion in...
