Abstract: 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. ...

Abstract: This study applied a generalized likelihood uncertainty estimation (GLUE) approach to a Hydrological Simulation Program—Fortran (HSPF) model used for the simulation of hydrology and transport of fecal coliform bacteria at ...

Abstract: Although the aquifers below the Eastern Shore of Virginia serve as the region’s only sources of fresh water, increased development and intensifying groundwater demands have put this resource at risk. Simulation modeling ...

Abstract: Objective functions to describe the operating and capital costs of granular activated carbon (GAC) treatment are incorporated into a management model for dynamic optimal pump-and-treat groundwater remediation design. The ...

Abstract: There often is difficulty enforcing the given constraints when applying a genetic algorithm (a flexible stochastic search method) to optimal ground-water remediation design problems. This paper compares two methods for ...

Abstract: A dynamic optimal control algorithm for ground-water remediation was extended to incorporate treatment facility capital costs, as a function of the peak operating rate. Our approach to including the capital costs of treatment ...

Abstract: In groundwater problems, there always is some uncertainty associated with appropriate values for aquifer parameters. Therefore an optimal remediation strategy identified by assuming a deterministic description of the system ...

Abstract: This work explores the sensitivity of optimal remedial design policies and their associated costs to the residual constraint violation, which is the sum of any small violations in constraints that may occur over all points ...

Abstract: Through a simulation modeling approach, this paper seeks to modify the design of detention ponds to preserve the natural ecological flows while satisfying the requisite regulatory flow requirements. This paper will utilize ...
