Preliminary analysis of turbidity measurements during a flushing operation in combined sewer channel

Flow turbidity at different elevations was continuously monitored in five cross-sections of a real combined-sewer channel stretch during a flush experiment. The preliminary analysis of the collected turbidity data in terms of quality and spatial variability of the time series is presented in this paper. Also, an Autoregressive Moving Average (ARMA) model was setup to evaluate potential prediction of turbidity values showing a good estimation performance with relatively small errors.
