An Evaluation of Pollution Flushing for Ben Beo Basin (Cat Ba Island, Hai Phong): Using the Estimation of Pollution Flushing
Main Article Content
Abstract
The results suggest that pollution exchange coefficient of Ben Beo are small, the basin may be at risk from water quality problems. The number of days required to achieve of 50% reduction in concentration for the mean tidal range: about 5 days using low and average values of b and 10 days using high value of b. The pollution flushing for maximum tidal range is strong. The number of days required to achieve a given percent dilution of the initial concentration is about 3 to 5 days for wide range of b values. However, model offers a reasonable approximation to heavy metal pollution.
