Linked Hydrodynamic and Biogeochemical Models of Water Quality in Shallow Lakes
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Aquatic Science and Environmental Engineering, Dept. of Civil Engineering, School of Engineering, Massachusetts Institute of Technology, 1982-03)Approaches to lake water quality modeling are critically examined with particular attention to the formulation of water quality transport as the link between hydrodynamics and biogeochemical reaction. A linked water quality ... -
A Mathematical Model for the Prediction of Unsteady Salinity Intrusion in Estuaries
(Cambridge, Mass. : Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, Department of Civil Engineering, Massachusetts Institute of Technology, 1972-02)The salinity structure of a tidal estuary fed by upstream fresh water sources is an important factor of water quality. In addition, this structure is intimately related to the circulation of the estuary because of density ... -
