Applications of Optimization, Numerical Analysis, and Parallel Processing to Groundwater Remediation

Groundwater remediation is an extremely expensive environmental problem. In this talk, the speaker will discuss the coupling of nonlinear optimal control algorithms to groundwater contaminant transport PDE models in order to identify cost-effective designs for groundwater remediation. Because of the computational difficulty of solving large-scale optimal control problems and the uncertainty of groundwater transport models, a number of approaches have been taken to improve computational efficiency and performance under uncertainty. The speaker will show brief video that includes animated computer graphics describing the movement of contamination through the groundwater in response to optimal and sub-optimal pumping strategies. She will also discuss applications to bioremediation problems and algorithms for parallel processing for nonlinear optimal control problems.
