Level and transport pattern of faecal coliform bacteria from tropical urban catchments

Urbanization and frequent storms play important roles in increasing faecal bacteria pollution, especially for tropical urban catchments. However, only little information on the faecal bacteria levels from different land use types and the factors that influence bacteria concentrations is available. T...

Intra-storm and inter-storm characteristics of FC bacteria were investigated in order to identify the level and transport pattern of FC.
