Adequação de modelo a susceptibilidade à erosão de solos no âmbito de microbacia na borda sul-amazônica

Abstract: Resumo: O trabalho teve como objetivo gerar um modelo de erodibilidade dos solos no âmbito da microbacia e, para tal, foram utilizadas bases cartográficas do Instituto Brasileiro de Geografia e Estatística (IBGE) referentes ao nível do solo; para a caracterização do relevo, foram utilizadas também duas cenas da Shuttle Radar Topographic Mission (SRTM), reamostradas para uma resolução espacial de 30 m, pelo projeto TOPODATA. Os principais usos/cobertura da terra foram obtidos aparitr das imagens RapidEye, senso… Show more

“…According to Cardoso et al (2006), the slope influences the relationship between rainfall and runoff in a basin, especially due to increases in surface runoff speed and reductions in water infiltration into the soil. Therefore, the topography is a key factor in predictive erosion models, as it directly influences the rate and volume of surface runoff of rainwater (Claudino et al, 2018). Soil physical properties, such as texture, porosity, and density, are directly associated with erosive processes (Simonetti et al 2018) and hence sediment loading into watercourses.…”

“…Conforme Gross, Santos e Pereira Filho (2016), avaliações sobre a declividade do terreno constituem-se em importantes instrumentos de apoio aos estudos sobre a potencialidade de uso agrícola e planejamento de uma determinada área. Conforme Claudino, Silva, Caioni, Silva, & Oliveira (2018) o uso de técnicas de geoprocessamento permite observar as mudanças de espaço e observar a variação das características do solo, em função da declividade e potencial de erodibilidade do solo.…”
