Abstract

The objective of this work was to establish sensitivity levels and recovery potentials for different types of channels in the 3 main rivers of the Tigre river hydrographic basin, in the municipality of São João do Tigre, a semi-arid region in Paraíba. For this purpose, the classification proposed by Rosgen (1994) was used, which at level I of analysis defines 9 general types of river channels through their location in the longitudinal profile, cross profile and plan shape of the channel. The second level of analysis proposes 94 subtypes of channels after the insertion of the analysis variables entrenchment, sinuosity, width / depth and texture of bed material. Thus, after the analysis at 6 points in the basin, it was possible to define 4 subtypes of channels and define which level of sensitivity and potential for recovery according to pre-established criteria in the methodology.
