The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) has been applied to the Patuxent River estuary, the Raritan River Estuary and the Arthur Kill. The applications were made to investigate the discharge of heated water from industrial facilities that use these waterbodies as cooling water sources. Current meter data were collected and comparisons of computed and observed velocities were made using spectral decomposition and coherency tests after the completion of the transport studies. Phasing between computed and observed velocities was generally very good; gain (the ratio of computed to observed velocity) varied between 0.6 and 1.0. This range reflected the use of a laterally averaged computation as well as differences in the locations of current meters.
