“…Table 3 provides a comparative order of specific erosions of some Mediterranean basins, although it is difficult to compare specific erosions of literature, because the data are often based on monthly (or more) river discharge and suspended sediment fluxes. Laignel et al [35] showed that the error produced on the erosion balance obtained from monthly sporadic data over 10 years could reach 44%.…”

In Algeria, the particulate flow in rivers is poorly quantified in the wadi due to the absence and the non‐standardization of the acquisition of measurement data. Most studies on particulate flows are quantified from time series of hydrometric stations. The present study is based on weekly sampling of water at the mouth of the Soummam watershed for the hydrological year 2011/2012. The sediment flux is analyzed from measurements of suspended solids (SS). The determination coefficients between the annual and seasonal “ liquid flow–solid flow‐” relationships vary from 75% to 82%, respectively. During this period, the watershed of 9125 km2 has provided a solid input estimated to 4.9 × 106 t yr−1, hence a specific flow of 538 t km−2 yr−1. In general, autumn floods were characterized by high concentrations of SS, which varies from 820 to 1275 mg L−1. The most important sediment transport volumes were observed during the period of December to February, this period is characterized by strong turbulence, due to extreme flows, favoring the largest volumes of solid transport. © 2015 American Institute of Chemical Engineers Environ Prog, 35: 204–211, 2016

Quantification and characterization of hydrological and sedimentary transfers are now major challenges to preserving European soils and water resources (Law on Water, Water Framework Directive). In northwestern France, stream water quality is currently reduced by suspended sediment. However, in these low‐energy water systems, sediment origin and dynamics into the catchment remain difficult to analyze from a local to a regional scale because of intermediary traps caused by landscape structure (hedgerow areas) and land use organization on the slopes. To provide a better understanding of sediment dynamics in these systems we proposed to analyze runoff dynamics on slopes and to assess slopes' contribution to the sediment budget of a catchment. This study is based on sediment connectivity analysis, used to accurately determine runoff dynamics between producing areas and the outlet of the catchment. This work is focused on the Lingèvres catchment (15 km2), a typical feature of the low‐energy water system located in the western part of France, in between open‐field and bocage landscapes. The results demonstrate that in a hedgerow landscape, known for its protective role against runoff connection to the river, sediment delivery from slopes is more important and efficient than in an open‐field area where no obstacles are observed. This is explained by diverse drainage densities and spatial organization of roads, and ditch and plot entries which induced differentiated sediment delivery from agricultural plots and the river. However, they also underlined the weakness of sediment delivery from slopes compared with sediment fluxes exported from the catchment. Conversely, they highlight the fundamental role of erosion processes due to agricultural practices and landscape organization in headwater systems, which seem to be the main functional area at the sub‐catchment scale.
