Resumo: | In the past, the occurrence of the territorial occupation in Brazil was extremely disordered and the inadequate use of the natural resources caused serious negative impacts on the water resources, such as the deterioration of the water and the consequent reduction in the water availability. Nowadays, there are few tools that allow the users and management agencies to accomplish an appropriate planning for water. In this scenery, this study was carried out to simulate and analyze both demand and supply of the water in agriculture in the hydrographic basin of the Jundiá creek, by using the software Perímetro . During the accomplishment of this study, the users of the surface wasters in the Jundiá creek basin and their main characteristics were registered in cadastre. In estimating the peak discharge in irrigation, the following factors were considered: the irrigated area, the total irrigation required, the system operation time and the irrigation period. The reference evapotranspiration was determined, by using the equation by Hargreaves-Samani. The peak discharge in irrigation, the possible maximum operational time and the effective operational time were taking into account in order to obtain the average captured discharge. According to the results, the following conclusions were drawn: the users of the water in the Jundiá creek basin belong to both agricultural and sanitation sectors; the Jundiá creek basin has an irrigated area around 1,108ha, as being 39.8% irrigated by conventional sprinkler, 8.4% by microsprinkling, 8.5% by trickle irrigation, 42.4% by central pivot and 0.9% by using hose; 51.7% users capture peak discharge above 25% Q90; 39.5% users demand an average discharge above 25% Q90; the maximum demand along the watercourse corresponds to 195.5% Q90 at the firth of the basin, and the highest average discharge represented 73%. The following were observed: the need for regularizing the flow rate of the watercourse, by constructing reservoirs, the use of the irrigation programming system to minimize the peak discharge; and even to substitute the less efficient irrigation systems by other more efficient ones. The Perímetro software showed to be efficient in either simulating the irrigation management and the demanded discharges available along the hydrographic basin. |

Atualmente, ainda existem poucas ferramentas que permitem aos usuários e órgãos gestores um planejamento adequado do uso da água. Nesse sentido, este estudo teve como objetivo simular e analisar a demanda e a oferta de água na agricultura para a bacia hidrográfica do Córrego Jundiá, utilizando o software Perímetro. Durante a realização do estudo, procedeu-se ao cadastramento dos usuários de águas superficiais da bacia do Córrego Jundiá e de suas principais características. Na estimativa da vazão de pico na irrigação, considerou-se a área irrigada, a irrigação total necessária, o tempo de funcionamento do sistema e o período de irrigação. A evapotranspiração de referência foi determinada, utilizando-se equação de Hargreaves-Samani. Para obter a vazão captada média, considerou-se a vazão de pico na irrigação o tempo de funcionamento máximo possível e o tempo efetivo de funcionamento. Os resultados obtidos permitiram as seguintes conclusões: os usuários de água da bacia do Córrego do Jundiá pertencem ao setor agrícola e saneamento; a bacia do Córrego Jundiá possui uma área irrigada de aproximadamente 1.108 ha, sendo 39,8% irrigada por aspersão convencional, 8,4% por microaspersão, 8,5% por gotejamento, 42,4% por pivô central e 0,9% utilizando mangueira; 51,7% dos usuários captam vazão de pico superior a 25% da Q90; 39,5% dos usuários demandam vazão captada média superior a 25% da Q90; a demanda de água máxima ao longo do curso d água corresponde a 195,5% da Q90 na foz da bacia, enquanto a maior vazão captada média representou 73%. Constatou-se a necessidade de regularizar a vazão dos cursos d água com a construção de reservatórios, de usar um sistema de programação de irrigação minimizando a vazão de pico e, até mesmo, substituir os sistemas de irrigação menos eficientes por outros mais eficientes; e o software Perímetro mostrou-se eficiente na simulação do manejo de irrigação e das vazões demandadas e disponíveis ao longo da bacia hidrográfica.Fundação de Amparo a Pesquisa do Estado de Minas Geraisapplication/pdfporUniversidade Federal de ViçosaMestrado em Engenharia AgrícolaUFVBRConstruções rurais e ambiência; Energia na agricultura; Mecanização agrícola; Processamento de produDemanda de águaSimulaçãoBacias hidrográficasWater requirementsSimulationWatershedsCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLA::ENGENHARIA DE AGUA E SOLOSimulação do uso da água do setor agrícola na bacia do Córrego JundiáSimulating the use of the agricultural sector water in the Jundiá creek basininfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf1282241https://locus.ufv.br//bitstream/123456789/3520/1/texto%20completo.pdf3242e2156bc9204e64881bf07da0b2e9MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain158552https://locus.ufv.br//bitstream/123456789/3520/2/texto%20completo.pdf.txtf84a250f8cac7853c5931583017f7a14MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3634https://locus.ufv.br//bitstream/123456789/3520/3/texto%20completo.pdf.jpg810c67edf4252b5efafabb2a53522f7aMD53123456789/35202016-04-08 23:14:16.856oai:locus.ufv.br:123456789/3520Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-09T02:14:16LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
