Abstract: A methodology for analyzing uncertain parameter ranges prior to model calibration or uncertainty analysis is presented. The method considers parameters that exist in complex models and are typically difficult to set using ...

Abstract: In this study, a combination of two modified versions of the SWAT 2005 model are used to estimate the impact of several best management practices on phosphorus loading to the Cannonsville reservoir in upstate New York as ...

Abstract: Cost-effective ways of remediating contaminated ground water by in situ bioremediation or other methods can be identified by coupling optimization and simulation methods. However, application of these methods to field-scale ...

Abstract: A coupled optimal control and simulation model is presented that selects injection and extraction well sites and pumping rates for cost-effective in-situ bioremediation design. Application of the model to a hypothetical ...

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: We have developed the first application of optimization techniques to the design of in-situ bioremediation, and have encountered a number of computational issues that have not arisen in previous efforts to optimize the ...

Abstract: This paper compares computational performance of eight optimization algorithms used to identify the most cost-effective policy for in situ bioremediation of contaminated ground water. Six of these methods have not previously ...

Abstract: Hydrologic (i.e., flow volumes) and sediment loading calibration and validation were completed for a New York City water supply watershed, the Cannonsville Reservoir basin, located in upstate New York. An unusually large ...

Abstract: A method for exploiting the sparsity structure of a finite-element simulation model in a linked dynamic optimal control model is developed. The linked optimization/simulation model has been used for the computation of ...

Abstract: A hierarchical optimization method is presented for an assessment of the potential maximum energy output of the Three Gorges Project and Gezhouba cascade hydropower stations in China. The optimization incorporates a detailed ...
