Item Área de preservação permanente nos cursos de água da Bacia do Rio São Pedro - PB(2018) Oliveira, Laura Maiara de Freitas; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/4957483273304674Since the beginning of human existence, this has been interfering with the stability and healthy development of nature. The vital need of fresh water for humanity, propels it to allocate itself in areas near the mirrors of water. However, today we understand that the constant presence of human actions and the removal of existing vegetation in these places, causes impacts to the sources and courses of water, which can result in the loss of these, to the environment. Considering the preservation and conservation of these environments, it is extremely important to investigate the areas considered as permanent preservation, which are protected according to the Brazilian Forest Code. The São Pedro River is the object of study of this work, it is located in rural area of the state of Paraíba. The objective is to investigate whether or not the legislation on Ciliary Forest, in this sub-basin, is considered as requiring 30 m of vegetation bordering its edges and radius of 50 m of vegetation in its springs. Geotechnology tools such as satellite images, SRTM images, Shapefiles and Spring software were used for these results, which allowed the observation and classification of these areas. The characterization of the occupation of the terrestrial surface and the antropism in the place were used. It was concluded that in the APPs of springs 50% and 28.33% are of sparse vegetation and soil exposed respectively, as well as, about 34.73% of sparse vegetation and 19.97% of soil exposed in the margins APPs. In the springs, 100% of the APPs have human interference, and approximately 85.92% in the river banks, which can generate serious future problems for the environment and even humans. Thus, it is observed the need for field studies in the most modified areas, as well as actions aimed at sensitizing the population on the importance of permanent preservation areas in rural areas.Item Suscetibilidade à erosão laminar (PNE) em Machados - PE(2018) Falcão, Cassiano José Lages Marinho; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/5445952042358738This paper aimed to estimate laminar erosion susceptibility in Machados County – PE, achieved using the adapted Universal Soil Loss Equation (USLE) and SIG for computing and analyzing data. The methodology used can be split in five steps: collection and integration of rainfall data on a thirty-year interval, local topography analysis using geoprocessing tools, laboratory analysis and posterior geolocation of local soils physical parameters and the final computation through the adapted USLE formulae. The achieved results allowed surmising that the County’s soil loss susceptibility is low, but significant, with a mean value reaching 368t/ha.year. The biggest influential factor was the topographic factor, averaging (…). Soil erodibility was considerably high, with a mean value of (…) and rain Erosivity, found to be (…) had the lowest impact on soil erosion. It is also possible to perceive a considerable spatial variation from the results, despite the reduced area of study, endorsing geotecnology use on its determination.Item Suscetibilidade à erosão laminar (PNE) em Machados - PE(2018) Falcão, Cassiano José Lages Marinho; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/5445952042358738This paper aimed to estimate laminar erosion susceptibility in Machados County – PE, achieved using the adapted Universal Soil Loss Equation (USLE) and SIG for computing and analyzing data.
