Resumo: | The protection of watercourses is motivated by legal instruments establishing permanent preservation areas (PPAs) along them, being defined from the width of the waterway. However, it is believed that there are other factors to consider, such as ecosystem services offered by PPAs. With the objective of developing a methodology for easy application that supports the identification of ecosystem services promoted by APPs along watercourses, in particular the stability of river embankments, this study developed a Rapid Assessment Protocol (RAP), compound for 7 parameters - vegetation, soil texture, stretch of river, slope inclination, soil depth in slope, width of the stream and, use and land cover, assigning them weights 0-4, depending on influence of their categories in the susceptibility to erosion of river embankments. The RAP was applied in 40 sampling units in the watershed of the Arroio Val de Buia, in Silveira Martins, RS. The end result of the RAP for each sample unit allowed the creation of classes of susceptibility to erosion, "stable", "susceptible" and "unstable". Simultaneously, we developed an algorithm programming in Python 2.6 (ArcGIS ® 10) language in order to determine indicators of fragility erosion of slopes of the watercourse areas and the contribution of these in susceptibility to erosion of river embankments. Statistical analysis (t test) revealed significant differences between the units evaluated by RAP. From the techniques of Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA), we observed the occurrence of clustering between different sampling units into two distinct classes, according to the categories of susceptibility to erosion resulting RAP. The basic parameters that determine the groupings were: soil, soil depth on slope, vegetation, portions of the stream and use and land cover. The PCA also showed that the first principal component (PC1) explained 43.54 % of the total variance, while the second explained 25.93 %, which showed the similarities between the "stable" sample units and "unstable", respectively. For indicators of fragility to erosion, the following information was obtained: maximum length of the tributary side, average steepness of maximum length side, accumulated tributary drainage area, average steepness of the cumulative tributary drainage area and, average velocity of maximum length side. The contribution of indicators of fragility in susceptibility to erosion of river embankments can be enhanced or attenuated depending on the category of the parameters evaluated in the RAP. It also pointed out that one of the products of this work was the algorithm programming that originated maps on indicators of fragility erosion down slope. Finally, it is concluded that the proposed protocol was presented as a good tool for rapid assessment of rivers with similar characteristics to Arroio Val de Buia, and useful for zoning and hierarchy of priority areas for environmental management and recovery degraded areas, especially those related to works of natural engineering, may be disseminated and applied, provided to regional characteristics. |

Contudo, acredita-se que há outros fatores a serem considerados, como os serviços ecossistêmicos oferecidos pelas APPs. Com o objetivo de desenvolver uma metodologia de aplicação fácil e que apoie a identificação de serviços ecossistêmicos promovidos pelas APPs ao longo de cursos d água, em particular a estabilidade dos taludes fluviais, este estudo desenvolveu um Protocolo de Avaliação Rápida (PAR), composto por 7 parâmetros - vegetação, textura do solo, trecho do rio, inclinação do talude, profundidade do solo no talude, largura do curso d água e, uso e cobertura da terra, atribuindo a eles pesos de 0 a 4, em função da influência de suas categorias na suscetibilidade à erosão de taludes fluviais. O PAR foi aplicado em 40 unidades amostrais na microbacia do Arroio Val de Buia, no município de Silveira Martins, RS. O resultado final do PAR para cada unidade amostral permitiu a criação de classes de suscetibilidade à erosão: estável , suscetível e instável . Simultaneamente, desenvolveu-se a programação de um algoritmo em linguagem Python 2.6 (ArcGIS® 10), a fim de determinar indicadores de fragilidade à erosão de áreas vertentes ao curso d água e a contribuição dos mesmos na suscetibilidade à erosão de taludes fluviais. A análise estatística (teste t) evidenciou diferenças significativas entre as unidades avaliadas pelo PAR. A partir das técnicas de Análise Hierárquica de Agrupamentos (AHA) e de Análise de Componentes Principais (ACP), foi possível observar a ocorrência de agrupamento entre as diferentes unidades amostrais, em duas classes distintas, de acordo com as categorias de suscetibilidade à erosão resultantes do PAR. Os parâmetros fundamentais que determinaram os agrupamentos foram: solo, profundidade do solo no talude, vegetação, trecho do curso d água e uso e cobertura da terra. A ACP mostrou ainda que a primeira componente principal (CP1) explicou 43,54% da variância total dos dados, enquanto a segunda explicou 25,93%, as quais evidenciaram as semelhanças entre as unidades amostrais estáveis e instáveis , respectivamente. Para os indicadores de fragilidade à erosão, foram obtidas as seguintes informações: comprimento máximo de vertente afluente; declividade média da vertente de comprimento máximo; área de drenagem afluente acumulada; declividade média da área de drenagem afluente acumulada e; velocidade média de vertente de comprimento máximo. A contribuição dos indicadores de fragilidade na suscetibilidade à erosão de taludes fluviais pode ser intensificada ou atenuada em função das categorias dos parâmetros avaliados no PAR. Cabe destacar ainda, que um dos produtos deste trabalho foi a programação do algoritmo que originou os mapas relativos aos indicadores de fragilidade à erosão de vertente. Por fim, conclui-se que o protocolo proposto apresentou-se como uma boa ferramenta de avaliação rápida de rios com características semelhantes às do Arroio Val de Buia, e útil para o zoneamento e a hierarquização de áreas prioritárias para o gerenciamento ambiental e a recuperação de áreas degradadas, especialmente aquelas ligadas a obras de engenharia natural, podendo ser difundido e aplicado, desde que adaptado às características regionais.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia FlorestalUFSMBRRecursos Florestais e Engenharia FlorestalÁrea de preservação permanenteCurso d`águaEstabilidade de talude fluvialProtocolo de avaliação rápidaIndicadores de fragilidade à erosãoPermanent preservation areaWatercourseRiver slope stabilityRapid assessment protocolIndicators of fragility to erosionCNPQ::CIENCIAS AGRARIAS::RECURSOS FLORESTAIS E ENGENHARIA FLORESTALIndicadores de fragilidade à erosão no apoio à definição de áreas de preservação permanente em riosIndicators brittleness erosion in support of definition of permanent preservation areas in riversinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisCruz, Jussara Cabralhttp://lattes.cnpq.br/3525141443261254Pereira, Rudiney Soareshttp://lattes.cnpq.br/9479801378014588Miola, Alessandro Carvalhohttp://lattes.cnpq.br/6330335959668033Kobiyama, Masatohttp://lattes.cnpq.br/7494734600375087Cruz, Rafael Cabralhttp://lattes.cnpq.br/1246969166762146http://lattes.cnpq.br/4124767739817947Monteiro, Josita Soares500200000003400300300300300300500c1603398-1815-4ff4-b6aa-273091cb7f373ee6f124-86a7-4a2a-b0a0-9113288af3872e2c4334-85e2-44df-a79c-cec0090a6040ea14e941-7ea9-4cb3-be2d-2927c62f7eddd7c6af40-4de2-4212-8b75-2051ee4c58b1ab8dfa9b-87fe-43f1-aa1a-552642d79635info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALMONTEIRO, JOSITA SOARES.pdfapplication/pdf5008371http://repositorio.ufsm.br/bitstream/1/3784/1/MONTEIRO%2c%20JOSITA%20SOARES.pdf1348ae61f69d922e3327616d40534f69MD51TEXTMONTEIRO, JOSITA SOARES.pdf.txtMONTEIRO, JOSITA SOARES.pdf.txtExtracted texttext/plain337719http://repositorio.ufsm.br/bitstream/1/3784/2/MONTEIRO%2c%20JOSITA%20SOARES.pdf.txt6ee76f35468a1ad9ca8df994f3829017MD52THUMBNAILMONTEIRO, JOSITA SOARES.pdf.jpgMONTEIRO, JOSITA SOARES.pdf.jpgIM Thumbnailimage/jpeg4779http://repositorio.ufsm.br/bitstream/1/3784/3/MONTEIRO%2c%20JOSITA%20SOARES.pdf.jpgb44d2da06cfda510e51d67c8a352001eMD531/37842021-10-22 15:11:38.817oai:repositorio.ufsm.br:1/3784Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2021-10-22T18:11:38Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
