Overbank sedimentation rates in former channel lakes: characterization and control factors

Abstract: Overbank sedimentation rates were studied in former channels of three rivers in south‐eastern France. Depth and spatial distribution of sediment, as well as geometry, hydrological connectivity and age of 39 lakes, were both measured and calculated. The mean sedimentation rate of lakes varied between 0 and 2·57 cm year−1. Sedimentation rates are linked to water depth and often undergo a decreasing gradient from the downstream outlet to the inner part of the lake. Multiple regression modelling demonstrates that … Show more

“…Most studies on abandoned channels have focused on processes and patterns in the aquatic zone, particularly gradients of hydrological connectivity (Hudson et al, 2012;Phillips, 2013), sedimentation and geomorphological patterns (Bravard, 1982;Gagliano and Howard, 1984;Shields and Abt, 1989;Citterio and Piégay, 2009;Constantine et al, 2010;Delhomme et al, 2013;Dieras et al, 2013), impacts of nutrient load and hydrogeological fluxes (Bornette et al, 2001), and diversity of aquatic vegetation and animal communities (Amoros and Bornette, 2002;Obolewski, 2011;Besacier-Monbertrand et al, 2012;Meyer et al, 2013;Toth et al, 2013). However, the larger floodplain environment that develops as abandoned channels fill has received much less attention, in particular the composition, biodiversity and temporal changes of the terrestrial plant community and its distribution along hydrogeomorphic gradients (but see Shankman, 1993;Holland et al, 2000).…”

“…The muddy layers represent deposition in over bank areas of the channels on a poorly developed levee and floodplain (cf. FilgueiraRivera et al, 2007;Citterio and Pié Gay, 2009;Shukla et al, 2010). The muddy sediments show prominent mottling due to activity of plant and animals.…”
