Abstract
ABSTRACT An operational predictive oil slick movement model is developed and applied to New York Harbor. This computer simulation employs hourly tidal currents for all stages of the tide as input data, combined with river flow and continuous wind data to predict oil slick movement. Slick spreading and transport is accomplished using a conservative form of the diffusion/advection equation. The shape of the slick as well as its possible separation into multiple slicks due to current divergence is predicted. Time steps on the order of three minutes and grid spacing of 200 meters allow short term, small scale slick position and shape predictions to facilitate quick response for location of sites for containment or cleanup activities. Hindcasting features allow for possible source location of the initial spill.
