LOI organic carbon as loss of weight on ignition, RPD apparent redox potential discontinuity, Spw pore water salinity, Ts water surface temperature, Hg total mercury, Dc distance from the confluence point, Ds distance from the main sewage input, Fm mean water flow speed
Depths were referred to the mean lower low water (MLLW), mean water flow speed were obtained for the sites within the channels by a modelling simulation
