In standing water, sedimentation rates increase with water depth and are therefore greatest in abandoned and cutoff channels [90].
Also, overbank flooding with a low suspended load leads to reduced infill of oxbows and potentially the absence of a clay sealing layer on the bed of cutoff channels. This will reduce the extent of standing water on the floodplain and inhibit wetland habitat development.
