GEOMORPHOMETRIC CHARACTERIZATION APPLIED TO STUDIES ON THE MORPHODYNAMICS OF THE SÃO JOSÉ WATERSHED - ITUIUTABA / MG

Abstract

Studying a hydrographic basin is of great importance for soil management, urban-environmental planning or territorial ordering. It is in basins that the impacts are most significant, since the dynamic balance of natural processes is disrupted and the effects as well as the responses to this disruption are manifested through urban environmental problems that affect part of society. With this problem in mind, the objective of this study was to carry out the geomorphometric characterization of the São José Watrshed, which is currently quite urbanized, to support studies on morphodynamics. Morphometry is understood here as the quantitative study of a watershed, which results in the measurement of aspects from the relief and from the river channels. To this end, the bibliographic review on the subject, fieldwork and a database prepared in a GIS environment were adopted as methodological procedures. Thus, the results obtained from the analysis of the geomorphometric parameters show that the watershed is susceptible to median flooding; event observed in the valley bottom areas, in periods of high rainfall volume, highlighting the anthropic action in the waterproofing of the soil in the slope.
