Resumo: | The purpose of this study is the monitoring of the behaviour of variables involved in determining the hydrological water balance by means of lysimeters installed in a small basin in the central depression of Rio Grande do Sul. The controlled variables were the precipitation, the runoff, the infiltration and storage of water in the soil. This work also presents the procedures for installation and repair of one volumetric lysimeters, besides the physical characterization of the area studied. The evaluation of water balance through of lysimeters measures considered different time scales and the daily evapotranspiration were obtained for intervals of 5 and 10 days. Due to structural problems with the lysimeters the evaluation of variables runoff, infiltration and evapotranspiration was undermined during the period of repair of the lysimeters (June 2008 to December 2008), and these variables only was available after this period (January to April 2009). The variables precipitation and water storage in soil were evaluated during all the period studied (June 2008 to April 2009). The monitoring of the storage of water in the soil within the lysimeters was performed by means of tensiometers vaccum-type installed at depths of 10, 30 and 70 centimeter and then also analyzed by use of equipment TDR installed at 30 centimeter of depth, outside the lysimeters. The results showed that in wet periods the soil moisture is higher in the depth of 10 centimeter, whereas in dry periods there is a higher concentration of moisture at depth of 70 centimeter. The lowest values of moisture were obtained for depth of 30 centimeter both in wet and in dry period. The storage of water in the soil measured by tensiometers and TDR to the depth of 30 centimeter follows the same trend of variation, even with the tensiometers located inside the lysimeters and TDR outside it. However, the storage measured by the tensiometers was higher and presented more changes in relation to storage measured with TDR's help. The water balance in the daily scale developed from measures lysimeters through of the equipment referred in this study, does not show good results, especially in periods in which heavy rain occurs, overestimating or underestimating the evapotranspiration. Already for periods of 5 and 10 days, there are better results when compared with the daily scale. |

As variáveis controladas junto ao lisímetro foram a precipitação, o escoamento superficial, a infiltração, o armazenamento de água no solo e a evapotranspiração. O trabalho apresenta ainda os procedimentos de instalação e reparos de um lisímetro de drenagem, alem da caracterização física da área em estudo. A avaliação do balanço hídrico por meio de determinações lisimétricas considerou diferentes escalas temporais, sendo a evapotranspiração obtida em intervalos diários, de 5 e de 10 dias. Devido a problemas estruturais com o lisímetro, a avaliação das variáveis escoamento superficial, infiltração e evapotranspiração foi prejudicada durante o período anterior ao concerto do lisímetro (junho de 2008 a dezembro de 2008), sendo estas variáveis monitoradas apenas para o período posterior ao concerto do lisímetro (janeiro a abril de 2009). Já as variáveis precipitação e armazenamento de água no solo, foram avaliadas durante todo o período de estudo (junho de 2008 a abril de 2009). O monitoramento do potencial de água no solo para determinar o armazenamento de água no solo no interior do lisímetro, foi realizado por meio de tensiômetros do tipo vacuômetro instalados nas profundidades de 10, 30 e 70 cm. O conteúdo volumétrico de água no solo foi monitorado com TDR instalado a 30 cm de profundidade, externamente ao lisímetro. Os resultados demonstram que nos períodos úmidos o conteúdo de água no solo é maior na profundidade de 10 cm, enquanto que nos períodos secos observa-se uma maior concentração na profundidade de 70 cm. Na profundidade de 30 cm têm-se os menores valores de conteúdo de água no solo tanto no período úmido quanto no período seco. O armazenamento de água no solo, determinado com dados do tensiômetro e do TDR, para a profundidade de 30 cm, segue uma mesma tendência de variação, mesmo com o tensiômetro estando localizado no interior do lisímetro e o TDR fora do mesmo. No entanto, o armazenamento computado com dados do tensiômetro foi superior, alem de apresentar maiores variações em relação ao armazenamento determinado pelo TDR. O balanço hídrico em escala diária, elaborado a partir de dados lisimétricos, pelo uso do equipamento referido neste estudo, não apresenta bons resultados, principalmente nos períodos em que ocorrem precipitações elevadas, superestimando ou subestimando a evapotranspiração. Já para períodos de 5 e 10 dias, observam-se resultados mais satisfatórios, quando comparados a escala diária.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia CivilUFSMBREngenharia CivilBalanço hídricoLisímetrosEvapotranspiraçãoWater balanceLysimetersEvapotranspirationCNPQ::ENGENHARIAS::ENGENHARIA CIVILComportamento das variáveis hidrológicas do balanço hídrico do solo em lisímetros de drenagemBehavior of the variables hydrological soil water balance in drainage lysimetersinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPaiva, João Batista Dias dehttp://lattes.cnpq.br/8797362461678439Righes, Afrânio Almirhttp://lattes.cnpq.br/5071492152716046Castro, Nilza Maria dos Reishttp://lattes.cnpq.br/5253343519757030http://lattes.cnpq.br/8643955703074641Feltrin, Rafael Matias30010000000340050050050030081e0fd8f-82cb-4fee-b955-800ec8ca5fd8cea3a59c-798b-4d42-9b37-93fa0e73481c02931287-333c-4ad9-9a69-91cae1515c4ba4d72c22-a188-40d4-8814-29fe09e1f0cfinfo:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALFELTRIN, RAFAEL MATIAS.pdfapplication/pdf3776645http://repositorio.ufsm.br/bitstream/1/7732/1/FELTRIN%2c%20RAFAEL%20MATIAS.pdfcc002dd093717def567ecd13ddf70559MD51TEXTFELTRIN, RAFAEL MATIAS.pdf.txtFELTRIN, RAFAEL MATIAS.pdf.txtExtracted texttext/plain169139http://repositorio.ufsm.br/bitstream/1/7732/2/FELTRIN%2c%20RAFAEL%20MATIAS.pdf.txt70dff986f5f8023a7c86b73a37914b08MD52THUMBNAILFELTRIN, RAFAEL MATIAS.pdf.jpgFELTRIN, RAFAEL MATIAS.pdf.jpgIM Thumbnailimage/jpeg5082http://repositorio.ufsm.br/bitstream/1/7732/3/FELTRIN%2c%20RAFAEL%20MATIAS.pdf.jpg4ab09b04b45f52d967e074e29ffa12b9MD531/77322023-04-24 15:04:24.701oai:repositorio.ufsm.br:1/7732Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132023-04-24T18:04:24Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
