    • Numerical Simulation of Solute Transport in Randomly Heterogeneous Porous Media: Motivation, Model Development, and Application 

      Tompson, Andrew F. B.; Vomvoris, Efstratios G.; Gelhar, Lynn W. (Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, Dept. of Civil Engineering, School of Engineering, Massachusetts Institute of Technology, 1988-12)
      A particle tracking, or "random walk" solute transport model is developed to study detailed contaminant movements through large, synthetic heterogeneous flow systems in porous media. Such simulations can be used to examine ...
    • Large-scale Dispersive Transport in Aquifers: Field Experiments and Reactive Transport Theory 

      Garabedian, Stephen P.; Gelhar, Lynn W.; Celia, Michael A. (Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, Dept. of Civil Engineering, Massachusetts Institute of Technology, 1988-01)
      A large-scale natural-gradient tracer test was conducted to examine the transport of reactive and nonreactive tracers in a sand and gravel aquifer on Cape Cod, Massachusetts. The movement and spreading of bromide, a ...
    • Copper Sulfate Treatment of Lakes and Reservoirs: Chemical and Biological Considerations 

      McKnight, Diane M.; Chisholm, Sallie W.; Morel, Francois M. M. (Cambridge, Mass. : Massachusetts Institute of Technology, Dept. of Civil Engineering, Division of Water Resources & Hydrodynamics, Ralph M. Parsons Laboratory, 1981)
      Since 1905, copper sulfate has been widely used as a means of controlling nuisance algae in drinking water reservoirs. Reservoir managers, relying on experience, have developed procedures which are generally successful in ...
