Abstract: Transient seepage patterns in the west dike station 58+00 of Wallace Dam are studied through a saturated‐unsaturated seepage analysis using a finite element solution technique. Numerical results obtained are presented and ...

Abstract: The analytical contaminant transport analysis system (

Abstract: The Agency for Toxic Substances and Disease Registry (ATSDR), U.S. Department of Health and Human Services, determined what portion of the city of Tucson received trichloroethylene (TCE)-contaminated drinking water from ...

Abstract: In this study, we formulate a contaminant source characterization problem as a nonlinear optimization model, in which contaminant source locations and release histories are defined as explicit unknown variables. The ...

Abstract: In this study we provide a methodology for the optimal design of water sensor placement in water distribution networks. The optimization algorithm used is based on a simulation-optimization and a single-objective function ...

Abstract: In this paper, the authors propose a new approach, the simulation–optimization method, to solve a nonlinear contaminant-source and release-history identification problem for a complex water distribution system. This approach ...

Abstract: An epidemiologic study of childhood leukemia and central nervous system cancers that occurred in the period 1979 through 1996 in Dover Township, N.J., is being conducted. Because groundwater contamination has been documented ...
