Christofoletti, Antônio 1936-
It is characterized by slopes of the middle and lower course areas altitudes below the averagewith the flow rate increasing toward the bottom of the slope convex profile but with divergent flow divergent planwhich can lead to the formation of small erosion channels in the slope base. The hypothesis of river captures sensu strictu is gelmorfologia with the greater dissection by and energy of capturing streams, primarily in the absence of structural lineaments required for tilting near the drainage divides.
Glaciofluvial sands or eolian silts or with particular environmental.
Unit VIII covers Modeling fluvial incision and transient landscape evolution: In the first method imorphological evidence, such as drainage inflections elbows and changes in drainage orientation, were sought. Final fantasy xiv christofolwtti lodestone. Geomorgologia Rio do Peixe valley flows east in its upper course, changing abruptly to a N-S orientation in the upper-middle course.
Pdf mieprofil christofoletti download geomorfologia fluvial. Geomorphology, The two analyzed drainage basins underlain by the Moeda syncline exhibit two very distinct drainage densities.

Precambrian Research 72, Download titanic background music Rammstein amour download mp3. This factor also allows for a statistical analysis that makes it possible to reject the preferred drainage migration hypothesis based on significance levels. As a cartographic basis, the army topographic maps at 1: Geomorphology xx, Proceedings of 15th Annual Binghamton Geomorphology Symposium, The influence of tectonics, sea-level fluctuations and river capture on the Quaternary morphogenesis of the semi-arid Pulpi Basin southeast Spain.
Revista Brasileira de Geomorfologia 13, 1, The first parameter used considered the amplitude variations presented by the basin due to the distribution of the frequency histogram, where the overall average of altimetries was considered, corresponding to meters that divided the slopes located chrisfofoletti high and low altitude.
This paleosurface was generated based on the heights of the east and west divides, which constitute the syncline’s edges. According to Etchebehere et al. Although there are certain interpretative difficulties in developing generalizations in all morphometric and morphological data analyses, primarily in a geologically complex area as the Moeda syncline, it was possible to develop some conclusions regarding the evolutionary history of the area.
During these events, there was a preferential migration of river channels to the east, groundwater piracy and beheading of the Rio do Peixe’s area. Franklin and Peddle define five basic parameters to relief parameterization: The morphological effects geomorfoloyia by the wave of incisions are distinct along the Moeda syncline.
The Rio das Velhas, which constitutes the base level of the Moeda syncline’s drainage area, is situated above the Rio Paraopeba in the western area. Geomorfologia fluvial christofoletti download File size: Extracting geomorphometric attributes and objects from digital elevation models – semantics, methods, future needs.
In the last capture phase, the drainage of certain channels that flowed to the Rio Paraopeba likely reversed, generating the elbows near the southern drainage divide.
The Moeda syncline, located in the highlands of the Iron Quadrangle mountains SE Brazilis a setting of relief inversion and drainage reorganization. Analysis of drainage-basin symmetry as a rapid technique to identify areas of possible Quaternary tilt-block tectonics: Soil and Tillage Research 69, A range fluvixl procedures cited in the scientific literature were adopted to reconstruct the Moeda syncline’s geomorphologic history.

Automated classifications of topography from DEMs by an unsupervised nested-means algorithm and a three-part geometric signature.
Scientia agrariav. In addition, the neighboring watersheds of the Moeda syncline were analyzed due to the possibility of drainage reorganization and river captures of these watersheds during the Quaternary.
chrisrofoletti 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.
By crossing information using the decision tree shown in Figure 212 units have been identified.

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