    • Technology and Policy Issues Involved in the Boston Harbor Cleanup 

      Morrissey, Shawn P.; Harleman, Donald R. F. (Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrodynamics and Coastal Engineering, Hydrology and Water Resource Systems, 1989-11)
      Introduction: Throughout history, disposing of human wastes has been a problem. In the late 1800's, when communities began to flourish, it was generally believed that human waste was the source of many diseases. The principal ...

    • A Physically Based Channel Network and Catchment Evolution Model 

      Willgoose, Garry; Bras, Rafael L.; Rodriguez-Iturbe, Ignacio (Cambridge, Mass. : Ralph M. Parsons Laboratory Hydrology and Water Resource Systems, Dept. of Civil Engineering, Massachusetts Institute of Technology, 1989-06)
      A catchment evolution and channel network growth model is presented. Elevations within the catchment are simulated by a sediment transport continuity equation applied over geologic time. Sediment transport may by modelled ...

    • Evaluation of Longitudinal Dispersivity from Tracer Test Data 

      Welty, Claire; Gelhar, Lynn W. (Cambridge, Mass. : Ralph M. Parsons Laboratory Hydrology and Water Resource Systems, Dept. of Civil Engineering, Massachusetts Institute of Technology, 1989-03)
      Introduction: Mathematical modeling of solute transport has become a standard tool for evaluating the movement and spreading of chemical contaminants in the subsurface aquatic environment. Most frequently, numerical ...
