Then, from the height values of the paleo-and current surface, the mean downwearing of the landform was calculated.

A Textbook of Geomorphology, second edition. The stream length-gradient index SLdefined by Hackmay be mathematically described in two ways. Revista Brasileira de Geomorfologia 13, 1, The basin is emphasized for defining the relief sculpturing and, in the words of Botelho”since the river basin is delimited considering geomorphological criteria, it has some advantage over the other planning units defined by other attributes, which present imprecise limits, such as those based on the types of vegetation or climate characteristics”.

The transverse topographic symmetry factor T indicates the presence of the main river channels’ preferred migration in the two analyzed watersheds Tables 6 and 7; Fig.

Morphological and morphometric analyses were carried out on GIS environment.

The river network’s orientation upstream of certain of these inflections is similar to the orientation of certain nearby rivers Figure 8.

The X unit covers However, slopes with null values are very rare in nature, so, very little of what is thought to be rectilinear really presents null curvature value, and presents values that belong to a tolerance range in the vicinity of cyristofoletti value instead.


If tectonic-structural explanations are discarded as causes of the anomalies, the knickzones can be understood as key features of the headward propagation of a wave of incision caused by captures BEGIN et al. The data obtained from the Moeda syncline reveal distinct morphological patterns in the main watersheds under investigation.

DEM-based identification of fluvial knickzones and its application to Japanese mountain rivers. This probability p can be calculated using the equation. Geographical Journal 5, Among all of the anomalies, only one is located on a tectonic lineament, indicating that there christofpletti explanations other than tectonic-structural ones for the majority of the anomalies.

Christofoletti, Antônio 1936-

That is, it is understood that the drainage basins are treated as geographical units where natural resources are integrated. The larger this value, the greater the relief between the headwater and the outlet and, hence, the greater the watershed’s mean slope. Therefore, it can be said that the studies on river basins are associated with the notion of system, including the headwaters, watershed, hierarchical drainage system, where every occurrence of events, of anthropogenic or natural origin, interferes with the dynamics of this system.

Christofpletti Brasileira de Geografia 2, p. The study area has an area of approximately km2, geomorvologia dendritic drainage pattern and several segments with anomalous inflections.

Earth Surface Processes and Landformsv. In general, the mean direction presents significant variations and the increase of the mean vectors T is similar to the values found in the statistical significance values p.


During the last phase of river capture, drainage reversal and elbows of capture developed in certain channels. These sub-basins are generally distributed across the entire basin, decreasing only in the middle course.

Knickzone propagation in the Black Hills and geonorfologia High Plains: The Moeda syncline is drained by two main drainage basins: Unit VIII covers The crossing of information using the decision tree with the parameters of altitude, slope, curvature profile and plan identified 12 representative units in the basin.

In the Rio do Peixe watershed, keeping in mind the unlikely litho-structural and regional explanations for the knickpoints Fig. Indian J Soil Conserv 29, Use of geographic information system GIS in assessing the erosion status geomprfologia watersheds.

This factor can be obtained using the equation. It occurs in the upper course of the basin formed by flat areas which are the most elevated areas, spatially positioned on the tops of slopes. Earth Surface Processes and Landforms 36, 13, The transverse topographic symmetry factor T can be obtained using the equation. Due to these conditions, the Moeda syncline is a highly appropriate area for studies of landform evolution and river capture.

The christofooetti obtained through the stream length-gradient indexes indicate the preferred locations of river segments with no anomalies and those with first-and second-order anomalies Figure 9.
