Abstract: A new technique based on Video Images for Storing and Retrieving parameters (VISR) and its application to model pollutant transport using the Lagrangian discrete parcel method is presented. The applications presented are dynamic schematization at run time, pollutant transport simulation where water surface area changes due to the rise and fall of water levels, spatial vector based shoreline and boom description, simulation of variable conditions along the shoreline, and convenient interactive boom placement in rivers. Because of the exploitation of graphics hardware capabilities available in microcomputers, the new technique in place of conventional techniques reduces main computer memory needs and greatly simplifies model development. The VISR technique is a result of advances in microcomputer hardware technology in recent years.
