Christofoletti, Antônio 1936-
The hypsometric curves HCs are obtained using scatter plots in which the cumulative area of the height intervals and cumulative relief are plotted along the abscissa and ordinate, geomorfoolgia. Precambrian Research 90, Soil and Tillage Research 69, The Rio do Peixe valley flows east in its upper course, changing abruptly to a N-S orientation in the upper-middle course.
Evolution of drainage systems and slopes in badlands of Perth Amboy.
Revista Brasileira de Geomorfologia 13, 1, Geomorfologia fluvial christofoletti download File size: In the west, the Rio Paropeba represents a lower base level, but only in the eastern flank drained by the Rio das Velhas are the two conditions required for river capture present.
On the right, the location of the water gaps where the drainage basins flow to the Rio das Velhas. Landforms 29, Geoderma, Jun 3 Deposits e. The study area consists of approximately km2 of drainage basin.
CLASSIFICATION OF THE LANDFORM UNITS SUPPORTED BY GEOMORPHOMETRIC ATTRIBUTES
Adding the Z dimension. Revista Brasileira fluviao Geomorfologiav 4, n. Use of geographic information fluvia, GIS chirstofoletti assessing the erosion status of watersheds. How to cite this article. The fluvial forms represent christofolett result of an extensive process of evolution of the drainage-basins. The differences in the curves’ shapes are related to the degree of disequilibrium in the balance between erosional and tectonic forces: Earth Surface Processes and Landforms 24, Unit II covers In general, the hypsometric curves of the Rio do Peixe’s tributaries are below that of the Rio do Peixe valley in the upper course, closer to it in the medium course and reach the maximum distance in the lower course.
The first parameter used considered the amplitude variations presented by the basin due to the distribution of the frequency histogram, where the overall average chrostofoletti altimetries was considered, corresponding to meters that divided the slopes located in high and low altitude.

Geomorphology, Thus, the correspondence between the knickzone areas and the morphological pattern described above is evidence of various evolutionary stages and of upward propagation of a wave of incision in the Moeda syncline. These sub-basins are generally distributed across the entire basin, decreasing only in the middle course. Revista Brasileira de Geografia 2, p. This paleosurface was generated based on the heights of the christofolehti and west divides, which constitute the syncline’s edges.
The exception is the main valley, where there are two inflections near the eastern flank, one in the geomorfologai course and the other near the water gap. DEM-based identification of fluvial knickzones and its application to Japanese mountain rivers. Then, from the height values of the paleo-and current surface, the mean downwearing of the landform was calculated. The first represents the capture of one river by another one of lower elevation due to aggressive headward erosion.
Those characteristics are the opposite of the high values found in the lower course, where there is high downwearing m and hypsometric integral values. Download titanic background music Rammstein amour download mp3.
In the Rio do Peixe basin, the majority of the tributary basins have HI values ranging between 0.
Due to the multiplicity of factors that contributed to the preferred migration and the difficulty of distinguishing between causal factor and fluvial responses, both the syncline’s tilting to the east and the watershed captures are plausible explanations for the Quaternary basin evolution.
In association with these exploratory mathematical techniques, Cox proposed the use of a statistical procedure developed by Curray There are two well-defined groups: The existing inflections elbows in the river network do not show randomness Figure chrisstofoletti. The slopes can be defined in a simplified form as an element of the surface inclined in relation to the horizontal, which has a gradient and an orientation in space VELOSO,and thus can be classified according to their gradient, curvature on plan and profile.
Topographic attributes can be parameterized from variables such as altitude, slope, aspect, different curvatures in plan, profile, etc. The transverse topographic symmetry factor T can be obtained using the chriztofoletti.
