Morphology and spacing of river meander scrolls - ScienceDirect
WebAs the river shifts laterally and chutes continue to form, point bars are molded into alternating ridges and swales that characterize a distinct topography known as meander scrolls. As the river changes its position, meander-scroll topography becomes preserved as part of the floodplain surface itself. Overbank processes also create microtopography. WebIn order to study the development of scroll bars while controlling the boundary conditions, an experimental meandering river was created in a 3x11m flume. Eight cases were performed in developed bends, which included the addition of sediment pulses and removal of part of the outer bend. Sediment pulses were added in order to determine if ... mwpropertyservice.co.uk

WebPoint bars are found in abundance in mature or meandering streams. They are crescent-shaped and located on the inside of a stream bend, being very similar to, though often smaller than, towheads, or river islands. Point bars are composed of sediment that is well sorted and typically reflects the overall capacity of the stream. WebMeander - Associated Landforms - Deposits - Scroll-bars Scroll-bars Scroll-bars are a result of continuous lateral migration of a meander loop that creates an asymmetrical ridge and swale topography on the inside of the bends. WebFeb 1, 2010 · This depositional blind tidal channel meander formation process is part of a larger scale systemic depositional process of delta progradation that includes distributary elongation, gradient reduction, flow-switching, shoaling, and narrowing.
