Abstract

n order to reveal the main impact factors for the concentration of Faecal Indicator Organisms (FIOs) for one of the UK's most popular beaches, namely Blackpool bathing beach, the EFDC model code has been modified and used to calculate the sediment and faecal coliform fluxes in Liverpool Bay, and the related bays and rivers, especially including the Ribble and Wyre estuaries and rivers. These rivers and estuaries are thought to be the main FIO sources for possible non-compliance of the famous bathing beach. In the paper, the main model modifications and related verifications for the sediment and faecal concentrations are presented. The model's predicted results show that: (1) the model results generally agree well with measured data, including sediment and faecal coliform concentrations in the estuary regions, (2) local inputs near the Blackpool beach may cause the high FIO concentrations on the beaches, (3) the FIO fluxes from the Wyre and Ribble river basins create adverse impacts especially for unfavorable weather conditions. In the long term, controlling the faecal coliform sources in the Ribble and Wyre river basins is key to guaranteeing that the FIO levels are compliant with the required standards in the future.
