Dynamique sédimentaire actuelle d'un système fluvial méditerranéen: l'Agly (France)

Long-term fluxes of dissolved and suspended matter in the Ebro River Basin (Spain)

“…Geographically close to the Ebro Basin, Rovira et al (2005) reported a specific export rate for SPM of around 8.5 t km À2 year À1 in the Tordera Basin (NE of the Ebro). Further north in France, Serrat (2000) and Serrat et al (2001) reported 103 and 40 t km À2 year À1 , respectively for the Agly and Têt rivers.…”

Suspended sediment transport in a semiarid watershed, Wadi Abd, Algeria (1973–1995)

“…Nor should suspended sediment flux be confused with the total sediment delivery which results from bedload charge, suspended sediment, and dissolved sediment (Serrat, 1999). Bed load is generally assumed to be a minor part of particulate matter flux, accounting for only approximately 5-10% (Eisma, 1998;Syvitski et al, 2003;see also ref.…”

Temporal distribution of suspended sediment transport in a Mediterranean basin: The Lower Tordera (NE SPAIN)

“…Consequently, suspended sediment concentrations show a high degree of scatter and sediment-rating curves can substantially underestimate or overestimate the concentrations (Horowitz, 2003). Various methods, such as subdividing the suspended sediment dataset seasonally (e.g., Walling and Webb, 1983;Mossa, 1988Mossa, , 1996Batalla and Sala, 1994), as a function of the hydrological flow conditions (e.g., Asselman, 2000;Hudson, 2003) or choosing a threshold discharge (e.g., Serrat, 1999) have been developed to improve the C-Q relationships. In this study, the primary dataset was divided into samples collected during low flows (≤3.5 m 3 s − 1 ) and those taken during flood events (N3.5 m 3 s − 1 ) and different relations were constructed for each case.…”
