SUMMARY:

The morphodynamics of a watershed can be associated with the dynamics of the processes acting on the
relief, erosion is a clear example of a relief sculpting agent being characterized as a natural phenomenon,
however, it is currently being accelerated by anthropic actions. The incorrect use and cover of the land
established in the drainage network of a basin can generate environmental problems such as the acceleration
of soil loss and increase in the production of sediments. This research aims to analyze the morphodynamics
together with land use and land cover activities and geomorphological dynamics of the upper course of the
Curimataú River basin in the state of Paraíba, based on three attributes: mapping of land use and land cover;
soil loss monitoring stations; analyze the geomorphological dynamics from the geomorphological mapping
of the area under study. To carry out the mapping of land use and land cover, two images from the Sentinel-
2 satellite with a resolution of 10 meters were used, one image corresponds to the dry period and the other
to the rainy period, the technique used to make the map was vectorization on screen. The geomorphological
mapping will be carried out through a merger between IBGE (2009) and Ross (1992) techniques, in order to
identify the relief compartments up to the 6th taxon and assess the information through field work. The
experimental monitoring stations are based on the Baldassarani and Girão (2018) stations that estimate soil
loss from the ground drawdown measured through erosion pins. The mapping of land use and land cover
identified seven classes based on BRASIL (2012) and BRASIL (2013), the uses and land covers that were
most susceptible to and intensified erosion were uncovered areas and agriculture, as they lack natural
protection of the land. soil, vegetation. An unprotected soil presents a decrease in infiltration rates and an
increase in surface runoff, which generates an increase in the production of sediments and soil loss in the
basin.
