PERDA DE SOLO E PRODUÇÃO DE SEDIMENTO APLICADO A BACIA DO RIO COXIM

Abstract

Currently, due to the evolution of technology, the human being has tools that help you understand nature and the surrounding world. Between the possibilities brought by these technological tools, it is possible to cite the research of hydrographic basins and their respective dynamics of operation, this being a of the main points of the present work. For the investigation of watersheds, one of the main existing software is InVEST. From the foregoing, the objective general is the presentation of a hydrosedimentological model applied to the river basin Cushion. The present work is justified on account of the problems of soil loss faced along the basin, making it necessary to carry out a prognosis so that future on-site ecosystem interventions are carried out more accurately, saving time and resources. From the literature review, although it has been found an abundance of works about the InVEST software, there were no found many ecosystem studies about the problem of soil loss in the basin of Rio Coxim, being this one of the first and main works about the problems ecological problems faced in the respective area. For the development of the research, used input data elaborated in previous works about the study region, data were collected regarding rainfall erosivity, soil erodibility and the Factors C and P referring to the place of study. The results indicate a great loss of soil in the northeast and south regions of the Basin, which respectively correspond to the cities Costa Rica and São Gabriel do Oeste, these being the main points that must suffer intervention to prevent the worsening of ecological problems in the Coxim River basin.
