摘要: A continuously discharged dissolved conservative tracer was simulated with the Chesapeake Bay Estuary Model Package to study pollutant transport in estuary response point source loads and impact of November, 1985 storm. visualization technology is applied show 3-dimensional concentration variations a continuous daily time sequence. The differential responses net during storms versus inter-storm periods can be observed from an MPEG movie. It may take 2–3 months for travel fall-line mouth river relatively dry seasons, only 2 weeks some medium storms, less than 5 days big Plots concentrations eleven selected locations provide quantitative information on flows. magnitude peaks related different weather events these reflect combined effects flows various directions locations. lower tributaries (which are closer mouth) affected more upper by at mid-tributary. storm materials effectively affect adjacent severely.
