...W. V. Lewis Abstract Discusses the effects of increase in discharge, comminution of load, the change from erosion to transport, and strata variation in the development of stream profiles and nick points. GeoRef, Copyright 2004, American Geological Institute. Reference includes data from...

.... These values were similar to those found in other studies, including that by Gades et al. (2000 ), who showed that the saturated till beneath Siple Ice stream had an R value of 0.16–0.32. The Briksdalsbreen data were filtered using a five-point (2.5 m) moving average to remove the spatial variation...

... of much larger volumes in higher-energy fluvial environments can create steps in the longitudinal profile (nick points), ponds, log jams, boulder deposits, gravel accumulations, and pools up- and downstream of deposits. Effects of debris flows of several thousand cubic meters in high-energy environments...

... Pliocene Remsburg Ranch beds (RRB). Bars represent the error associated with the combined median grain size value of n Wolman point count measurements. Figure 3. A: Long profile and slope ( S ) of present-day base of Ash Hollow Formation (AHF) surface and North Platte River, compared...

... and Whipple, 2006 ; Gallen et al., 2013 ). Hence, we use the distribution of knickpoints in comparison with elevation and lithologic boundaries to unravel tectonic and lithologic controls on channel profiles. The final metric that we use to analyze the stream network is χ (Chi), an inverse integral...

... (Section 4.7). If the delta sequence deposited earlier in the cyclothem was still partly emergent, this would have enhanced incision, which started at the river mouth and cut back up the channel by nick point recession ( Fig. 17 ). With this process, nick point recession is only active for a short time...

... as fast as nick-point advance up rivers so that the distribution of successive erosion cycles bears no relationship to the drainage pattern whatsoever” (King 1953 , p. 742). Assessing which of these rival theories best explains a particular region is no simple task, and Blume ( 1976 ) has warned...

... including the West Arm and Muir Inlet. Figure 4. Generator-injector (GI) gun profile from A–A′. Numbered basins correspond with locations on Figures 1 and 3 . Basin 10 and the entrance sill morainal bank are shown enlarged in the inset. Shot points are shown across the horizontal axis...

... checked in the field to explore their significance/causes. These observed nick points of the streams of the mapped area have been further checked to correlate with geology of the area in particular the lithologic control or the structural control. Drainage map ( Figs. 3 ) has been prepared based...
