RESUMO:

The present study of the dissertation consists of searching through morphopedological optics, which is the intersection of soil analysis, source material and relief, to analyze the causes of laminar and linear erosive processes in the sub-basin of the Piraputanga stream, a tributary of the Cabaçal river, in the municipality of Reserva do Cabaçal/MT. The research has great importance for the contributions regarding the environmental quality, since it is the headwater of the Upper Paraguai Basin. For the study, the main objective was to describe the erosive processes found within the Morphopedological Compartments and to point out prognostic means for them, in addition, it was necessary to carry out several specific objectives to reach the object of study, such as: raising the bibliography about of the theme, describe the historical process of occupation and land use in the basin, map and characterize the geoenvironmental factors of geology, geomorphology, pedology, climate, vegetation and use and cover, produce the final morphopedological map, of the collection sites and points erosive, Characterize the susceptibility to laminar and linear erosion by morphopedological compartment, analyze the current situation of the erosive processes and factors of the sub-basin, and, later, present suggestions for improvements to the environmental quality for the observed problems. The methodology used for the research was divided into seven stages: theoretical support, thematic mapping, geo-environmental survey, digital cartography: application and production of the morphopedological map, field work, laboratory work, erodibility classification. Within these segments, six morphopedological compartments were found, namely: CM-I Chapada, CM-II Broad and medium hills, CM-III escarpments, CM-IV Valley bottoms, CM-V Terraces and plains and CM-VI Hills and isolated hills. The correlation of these with the declivity presented by each one was performed, and from this, the susceptibility to laminar and linear erosions was removed. Finally, it was noted that CM-II Broad and medium hills was the compartment classified as most susceptible to erosion, classified by class I: extremely susceptible to laminar erosion and Extremely susceptible to ravines and gullies for linear erosion. Bearing these characteristics, the highlighted morphopedological compartment presents a gully of great expressiveness, described in the text of the work. The second most susceptible morphopedological compartment is the CM-VI isolated hills and hillocks, characterized as class II, Very susceptible to laminar erosion and very susceptible to ravines and little susceptible to gullies for linear erosion. Finally, the results showed, in short, sandy soils, reliefs with slopes that favor surface runoff and, as a result, most morphopedological compartments susceptible to erosive processes.
