Scenarios of intermittent E. coli contamination from sewer overflows to shellfish growing waters: the Dart Estuary case study

Sewage overflows (SOs) and Combined Sewer Overflows (CSOs) significantly contribute to the bacterial contamination of coastal waters, which is of especial concern for aquaculture, a growing industry worldwide. Hydrodynamic and water quality models were used to investigate impacts of CSO discharge fr...
