  abstract = {{T}he occurrence of pathogen bacteria in surface waters is a threat to public health worldwide. {I}n particular, inadequate sanitation resulting in high contamination of surface water with pathogens of fecal origin is a serious issue in developing countries such as {L}ao {P}.{D}.{R}. {D}espite the health implications of the consumption of contaminated surface water, the environmental fate and transport of pathogens of fecal origin and their indicators ({F}ecal {I}ndicator {B}acteria or {FIB}) are still poorly known in tropical areas. {I}n this study, we used measurements of flow rates, suspended sediments and of the {FIB} {E}scherichia coli ({E}. coli) in a 60-ha catchment in {N}orthern {L}aos to explore the ability of the {S}oil and {W}ater {A}ssessment {T}ool ({SWAT}) to simulate watershed-scale {FIB} fate and transport. {W}e assessed the influences of 3 in-stream processes, namely bacteria deposition and resuspension, bacterial regrowth, and hyporheic exchange (i.e. transient storage) on predicted {FIB} numbers. {W}e showed that the {SWAT} model in its original version does not correctly simulate small {E}. coli numbers during the dry season. {W}e showed that model's performance could be improved when considering the release of {E}. coli together with sediment resuspension. {W}e demonstrated that the hyporheic exchange of bacteria across the {S}ediment-{W}ater {I}nterface ({SWI}) should be considered when simulating {FIB} concentration not only during wet weather, but also during the dry season, or baseflow period. {I}n contrast, the implementation of the regrowth process did not improve the model during the dry season without inducing an overestimation during the wet season. {T}his work thus underlines the importance of taking into account in-stream processes, such as deposition and resuspension, regrowth and hyporheic exchange, when using {SWAT} to simulate {FIB} dynamics in surface waters.},
