Impact of the hydrological regime and forestry operations on the fluxes of suspended sediment and bedload of a small middle-mountain catchment.

• Accurate monitoring of solid exports to estimate erosion flux. • Major role of delayed-flow events in solid export dynamics. • Small forestry operations with no protection measures can significantly disturb solid fluxes. • Immediate tree harvesting impact on the suspended sediment flux and delayed impact on the bedload flux.
