Resumo: | In areas of native forests, interception of rain precipitation trhough the vegetation is an important variable of the water balance. This research analyzed the interception process in two areas of deciduous forest at Santa Maria RS; along river Vacacaí Mirim. The variables monitored from March / 2013 to March / 2014 were: incident precipitation, stemflow and throughfall. The incident precipitation was monitored by a rain gauge type vats-tipper and a rain gauge, and also checked by INMET. The internal precipitation was monitored in both areas (I and II), with dimensions of 12 m x 50 m and 13 m x 45 m respectively. The stakes were installed at 40 or 60 cm of height. In both areas 101 stakes were allocated for disposal of 40 interceptômetros. Tere were 20 of these remained fixed and 20 were rotated. The stemflow was determined by monitoring the flow in three trees chosen within each area and the interception was calculated as the difference between precipitation and the sum of throughfall and stemflow. The highest interception was found in the area I. The stemflow in area II was lower as reported by other authors, showing that this variable can not be ruled of interception study. The internal precipitation variation ranges and interception were similar to those reported in other studies. The average of rainfall for the internal fixed and mobile interceptômetros was not significant. The interception in the experimental area I was 46.63% of the incident rainfall and the experimental area II was 43.93% of the incident rainfall. The results showed that the interception is a key component of the hydrological cycle and generally underestimated by hydrological models. The research concludes that the study of interception in soils with forest cover is essential for determining the water balance of an area. |

Esta pesquisa analisou o processo de interceptação em duas áreas de floresta estacional decidual, na região de Santa Maria - RS, na cabeceira da bacia do Rio Vacacaí Mirim. As variáveis monitoradas no período de março/2013 a março/2014 foram: precipitação incidente, escoamento pelo tronco e precipitação interna. A precipitação incidente foi monitorada por um pluviógrafo tipo cubas-basculantes e por um pluviômetro. A precipitação interna foi monitorada nas duas áreas (I e II), com dimensões de 12 m x 50 m e 13 m x 45 m, respectivamente. As estacas foram instaladas a 40 ou 60 cm do solo. Nas duas áreas foram alocadas 101 estacas para disposição de 40 interceptômetros, sendo que 20 permaneceram fixos e 20 foram rotacionados. O escoamento pelo tronco foi determinado por meio de monitoramento do escoamento em três árvores escolhidas dentro de cada área e a interceptação foi calculada pela diferença entre precipitação e a soma da precipitação interna e o escoamento pelo tronco. O maior valor de interceptação foi verificado na área I. O escoamento pelo tronco na área II foi inferior aos valores verificados por outros autores, revelando que essa variável não pode ser descartada o estudo da interceptação. Já as faixas de variação de precipitação interna e da interceptação ficaram próximas àquelas registradas em outros estudos. As médias da precipitação interna por interceptômetros fixos e móveis não foi significativa. A interceptação na área experimental I foi 46,63% da precipitação incidente e na área experimental II foi 43,93% da precipitação incidente. Os resultados mostraram que a interceptação é um componente fundamental do ciclo hidrológico e, em geral, subestimada pelos modelos hidrológicos. A pesquisa conclui que o estudo da interceptação em solos com cobertura florestal é fundamental para a determinação do balanço hídrico de determinada área.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AmbientalUFSMBREngenharia AmbientalPrecipitação incidentePrecipitação internaEscoamento pelo troncoInterceptaçãoIncident precipitationInternal precipitationStemflowInterceptionCNPQ::ENGENHARIASInterceptação da chuva em floresta estacional decidual em Santa Maria, RSRain interception in deciduous forest in Santa Maria, RSinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPaiva, João Batista Dias dehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783817A6Santos, Irani doshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4700151T4Forgiarini, Francisco Rossarollahttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4705275Y7http://lattes.cnpq.br/4415949343903516Deon, Elis Helene de Andrade30000000000940050030050030081e0fd8f-82cb-4fee-b955-800ec8ca5fd82ea6796e-4411-4df9-aed2-1d7b32c1c70e7f62e79f-9ca5-44ef-a79d-6e4bd239bb5065ed4d76-888f-4551-9ae8-0247c9d33063info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDEON, ELIS HELENE DE ANDRADE.pdfapplication/pdf1777043http://repositorio.ufsm.br/bitstream/1/7646/1/DEON%2c%20ELIS%20HELENE%20DE%20ANDRADE.pdf02efa0cf3d751e121f78c88dfa57cbe3MD51TEXTDEON, ELIS HELENE DE ANDRADE.pdf.txtDEON, ELIS HELENE DE ANDRADE.pdf.txtExtracted texttext/plain88708http://repositorio.ufsm.br/bitstream/1/7646/2/DEON%2c%20ELIS%20HELENE%20DE%20ANDRADE.pdf.txtbc82c6b29135c361366c5cb92542d631MD52THUMBNAILDEON, ELIS HELENE DE ANDRADE.pdf.jpgDEON, ELIS HELENE DE ANDRADE.pdf.jpgIM Thumbnailimage/jpeg5023http://repositorio.ufsm.br/bitstream/1/7646/3/DEON%2c%20ELIS%20HELENE%20DE%20ANDRADE.pdf.jpgf52ada506cda8bebce9df6b015802f4eMD531/76462017-07-27 18:34:05.335oai:repositorio.ufsm.br:1/7646Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2017-07-27T21:34:05Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
