Analysis of dispersion and transport of saline water discharge around an engineered beach coast

Presenter: Eric C. Cruz

The dispersion and transport of a saline effluent discharge (SED) into the nearshore area of a developed beach zone is studied via numerical modeling based on the dispersion-advection equation of a conservative quantity at the source. Tidal currents modified by the engineering structures are characterized via a coastal hydrodynamics model considering both tidal forcing and non-storm wind shear during tidal cycles of the 2 seasons. Simulated time-motion salinity distributions are analyzed to yield indicative resurgence times and statistical maximum salinities to compare the dispersion patterns due to SED introduction at 2 alternative locations.
