WebJan 1, 2000 · After the continuous uplift of the range, resistant rocks cause the deflection of a transverse river and its change to a longitudinal river along the back flank of the range. WebNov 1, 2016 · Lowering of water stages associated with given discharges indicates channel incision. Hydraulic importance of river incision by a given absolute amount increases with decreasing river size. Hydraulic effects of channel incision depend on lateral stability/mobility of an incising river.

WebMar 1, 2005 · On the basis of the Manning equation and basic mass conservation principles, we derive an expression for scaling the steady-state width (W) of river channels as a function of discharge (Q), channel slope (S), roughness (n), and width-to-depth ratio (α): W = [α(α + 2) 2/3] 3/8 Q 3/8 S −3/16 n 3/8.We propose that channel width-to-depth ratio, in … WebMostly furrows incising the glabella are absent, but incomplete furrows in some species and deeply impressed transglabellar furrows also occur. There is a delicate equilibrium that …
WebAlthough the river efficiently incised a new channel through the deposit, subsequent rates of lateral erosion were slowed by the tall, cohesive banks, limiting the total volume of sediment delivery. Once entrained, however, most landslide material was rapidly transported downstream in suspension with little geomorphic effect. Web[9] We use remnants of the old river channel, called straths, to measure fluvial incision [Pazzaglia and Brandon, 2001]. Straths are flat eroded surfaces cut into bedrock. They are found in the hillslopes above an actively incising river and are attributed to periods of time when the river was able to incise into bedrock and to cut a broad flat ...
WebAn incised river is defined as a river that is experiencing bed-level lowering. From the viewpoint of geomorphological process, mountain rivers either were or are incised rivers. … WebNov 1, 2016 · Where the incising rivers remained laterally stable, incision has mostly reduced water stages associated with low flood discharges and considerably decreased flow velocities over the floodplains.
WebMar 19, 2010 · Spatially averaged river sinuosity generated from digital elevation data peaks in the typhoon-dominated subtropics, where extreme rainfall and flood events are common, and decreases toward the equatorial tropics and mid-latitudes, where such extremes are rare. Once climatic trends are removed, the primary control on sinuosity is rock weakness.
