The impact of coastline change and urban development on the flushing time of a coastal embayment, Kingston Harbour, Jamaica
Bulletin of marine science
Date of Publication
Kingston Harbour, Jamaica has a history of eutrophication due to nutrient loadings emanating from the city of Kingston. In this study a two dimensional, numerical, hydro-dynamic model of the harbor is used to assess the impact of coastal development at the western end of the harbor and on the evolution of this eutrophication. The model shows that the development did not materially affect the flushing of the harbor; therefore the rapid increase in eutrophication since 1970 must be linked to concurrent population pressure. However, the coastal modification has altered the circulation pattern within Hunts Bay and has reduced the exchange between Hunts Bay and the remainder of Kingston Harbour. Increased siltation and further eutrophication within Hunts Bay are predicted as the impact of the modification. The model was also used to investigate the feasibility of aiding the flushing of the harbor by adding a second entrance. The model showed that such an opening is likely to have negligible impact on the present flushing time.....
