Effect of regenerated soil structure on unsaturated transport of Escherichia coli and bromide

► We studied the transport of bacteria and bromide in re-structured soil columns. ► Under unsaturated condition BTCs and HYDRUS-1D model were used to estimate the model parameters. ► The peak of the BTCs for bacteria occurred earlier than that for bromide. ► Results showed that the HYDRUS code is a powerful model for simulating the bacterial transport.
