Coarse and fine sediment sources in nested watersheds with eucalyptus forest

Knowledge on sediment behavior in watersheds contributes to properly implement soil and water conservation practices and solve sediment‐related environmental problems. We examined the effects of suspended and bedload sediments and location of potential sediment sources. We used geochemical propertie...

Description
Summary:Knowledge on sediment behavior in watersheds contributes to properly implement soil and water conservation practices and solve sediment‐related environmental problems. We examined the effects of suspended and bedload sediments and location of potential sediment sources. We used geochemical properties to calculate sediment contributions, with sediment fingerprinting approach, in a watershed (0.98 km2) and in a sub‐watershed (0.39 km2) cropped to commercial eucalyptus along with native forest. The sediment sources evaluated were eucalyptus stand, stream bank along the main channel, and unpaved roads in each watershed. Two size‐fractions of source and sediment samples including fine (
