Pollutant transport and residence time in a distorted scale model and a numerical model

A systematic investigation of the circulation, pollutant transport and residence time in a distorted scale model of the Windermere Basin was undertaken by using a numerical approach. A numerical hydrodynamic model was developed to simulate the circulation pattern in the basin. The experimentally validated flow circulation was used as input to the pollutant transport model to imulate the transport of a pollutant Continuous Iy introduced at the inlet of the basin. The simulated re utt were found to be in good agreement with the experimental measurements. With the aid of the validated model, the influence of the wind, recirculation and dead zone, and construction of dikes on the residence time distributions in the basin were examined.
