“…Sediment transport dynamics is controlled to a large extent by the diverse behavior of coarse and fine sediment particles and temporary channel storage, and these processes have a bearing on the patterns of sediment delivery with increasing scale (Patil et al, ). Rodrigues et al () observed that the predominant direction of hysteresis loops was clockwise, which suggest proximity of the sediment sources location (Eder, Strauss, Krueger, & Quinton, ; Seeger et al, ), possibly from the main channel.…”

“…The effects of Eucalyptus spp. forests on water and land resources are not well known, and there are uncertainties about the ability of production land to support planted forests without degrading those natural (Reichert et al, ; Rodrigues et al, ). Sediment in suspension and bedload sediment cause environmental problems (Bilotta & Brazier, ; Haddadchi, Olley, & Pietsch, ; Owens et al, ).…”

“…Only part of the sediment entering the stream system is not fully transported to the watershed exit (Caitcheon et al, 2012), and thus, sediment yield represents a lesser portion of total sediment produced in the watershed (Minella, Walling, & Merten, 2014;Rodrigues et al, 2014). Small watersheds show sediment deposition on footslopes, floodplains (Bonumá et al, 2013), and within channels (Prosser et al, 2001).…”

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 (<0.063 mm) and coarse (0.063–2 mm) particles were analyzed. Particle size and source location in the watershed are major factors affecting the contribution of sediment sources. The closer the sediment source, the higher the sediment source contribution, especially for coarse particles. Runoff connectivity probably explains large changes in sediment source contributions over very short distances between sampling sites. The stream bank had the greater relative contribution to sediment yield, suggesting that the focal point for erosion control practices should be the channel rather than on the slopes with eucalyptus or riparian vegetation. Future studies should consider uncertainties in grouping sediment sources with a much better signal‐to‐noise ratio.
