Resumo: The objective of this research was to apply the hydrological model SWAT under different soil use scenarios to evaluate water availability through space and time in the Araranguá watershed. The scenarios evaluated were: I) Current soil use, that is, mostly rice cultivation in paddy fields; II) Agriculture land replacement by forestry; and III) Agricultural land replacement by bare soil. The results obtained indicate that SWAT was efficient in modeling water distribution in the Araranguá basin. Moreover, it was verified that the average daily flow of water in the Araranguábasin occurred in the bare soil scenario. These results are supported by the reduced water infiltration and increased runoff verified in this scenario. Nevertheless, the bare soil scenario presented the highest number of days in which the estimated daily water flow (Qsim) of the basin was below the actual minimum flow through 95% of the time (Q95). The forestry scenario, in its turn, presented the lowest occurrence of Qsim < Q95 events, suggesting it may support a more stabilized water flow in the Araranguá basin throughout the year.

Este trabalho teve como objetivos aplicar o modelo hidrológico SWAT (Soil and Water Assessment Tool) à bacia hidrográfica do Rio Araranguá e avaliar, por meio de cenários, a influência das atividades agrícolas sobre a distribuição espacial e temporal da disponibilidade hídrica da área estudada. Os cenários estudados foram: I) uso atual, com predominância da rizicultura nas áreas agrícolas; II) substituição da agricultura por reflorestamento; e III) remoção da cobertura vegetal das áreas agrícolas. Os resultados demonstraram a eficiência do modelo em representar o regime hidrológico da área estudada. Além disso, pode-se verificar que a vazão média diária anual foi maior no cenário com solo exposto, sendo esse aumento atribuído à redução da infiltração de água no solo e ao aumento do escoamento superficial. Entretanto, apesar desses resultados, o número de dias em que a vazão diária simulada (Qsim) permaneceu abaixo da mínima observada em 95% do tempo (Q95) foi maior nesse cenário. O cenário com reflorestamento apresentou a menor ocorrência de Qsim < Q95, sugerindo maior regularização de vazão ao longo do ano.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2020-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/680Agropecuária Catarinense Journal; Vol. 24 No. 1 (2011); 65-70Agropecuária Catarinense; v. 24 n. 1 (2011); 65-702525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/680/579Copyright (c) 2020 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessBlainski, ÉvertonSilveira, Fabio AlvesConceição, GersonGarbossa, Luis Hamilton PospissilVianna, Luiz Fernando2021-02-17T14:35:51Zoai:ojs.publicacoes.epagri.sc.gov.br:article/680Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-02-17T14:35:51Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
