Since the beginning of geomorphological research, phenomena such as river capture, drainage expansion and relief inversion have been important to our understanding of long-term landform evolution DAVIS, ; ; BOWMAN, In the first method imorphological evidence, such as drainage inflections elbows and changes in drainage orientation, were sought.

The processes range from top to the bottom of this portion of the slope through the decrease on the energy of the divergent flow concave profile and divergent plan.

Unit IV covers approximately It occurs mainly associated to unit I in the more flat portions, spatially positioned in the upper third of the slope.

The majority of the Rio do Peixe watershed displays a low height variation, with a sharp relief increase in only a relatively small area. The application of a digital relief model to landform analysis in geomorphology.

Soil and Tillage Research 69, The main inflections elbows 2, 3, 4 and 5 trend east, whereas the possible capturing streams downstream of the elbows are in states of much higher dissection than are the upstream drainages. Geological Society of America Bulletin 82, Geological Geomprfologia Professional Paper A The ordinate shows elevation mand the abscissa shows the horizontal scale m. The first six units correspond to the upper course and the last six units to the middle and lower course of the basin.

Geomorphology 69, Earth-Science Reviews 67, In the eastern portion, there is a considerable drop to the south, i. There is a predominance of morphogenetic processes of erosion in the superior portions of the slope with deposition at the base. Due to these conditions, the Moeda syncline is a highly appropriate area for studies of landform evolution and river capture. On the right, the location of the water gaps where the drainage basins flow to the Flugial das Velhas.

It is affected by NW-SE fluvkal faults with sinistral and dextral displacements of hundreds of meters. It represents slopes of the upper course areas, with the flow rate increasing toward the bottom of the slope, and divergent flow that can induce the formation of various erosional channels in the lower third of the slope.

Evolution of drainage systems and slopes in badlands of Perth Amboy. The development of certain English rivers. Boyce discolors his restless.

Drainage density and drainage inflections The two analyzed drainage basins underlain by the Moeda syncline exhibit two very distinct drainage densities. Geonomos 8, 1, One is located in the middle course, near the dextral strike-slip faults, where there are two well-defined inflections. To characterize the slopes of the basin a quantitative analysis through geomorphometric parameters geomorphometry or digital analysis of the relief was carried out SILVEIRA et al.

July 05, ; Accepted: Ffxiv pc client download rffxiv. In the Rio do Peixe watershed, the drainages upstream of the elbows exhibit orientations similar to those of other channels within a given watershed, indicating a possible internal reorganization of the river network.

Morphological and morphometric analyses were carried out on GIS environment. University of California, Thus, the morphogenetic events responsible for the evolution of the basin underlain by the Moeda syncline during the Quaternary may be attributed primarily to river captures sensu strictu, diversion and beheadingneotectonic causes and, locally, to lithologic and structural patterns.
