Abstract: The recently developed thermodynamically constrained averaging theory is briefly summarized as a tool for the building of rigorous macroscale models of transport phenomena in complex systems. The ...

Abstract: During the last several years, spirited discussions have taken place within the hydrogeologic community regarding the status and future of research in this field of scientific endeavor; some of these exchanges have found ...

Abstract: This paper presents a new mathematical model of bacterial regrowth in distribution systems, which combines hydraulic calculations, inclusive of dispersion, with a description of the following microbial processes: free and ...

Abstract: A simple laboratory test, referred to here as the dredging elutriate test (DRET), was sought to predict the concentration of contaminants in the water column at the point of dredging. The DRET is procedurally similar to ...

Abstract: This work advances the mathematical modeling of ion exchange treatment in completely mixed flow reactors in which there is recycle and regeneration of the ion exchange resin. The most common application of this process is ...

Abstract: Concerted efforts to remediate subsurface systems contaminated with dense nonaqueous-phase liquids (DNAPLs) have met with limited success when measured by comparing solute concentrations to drinking water quality standards. ...
