Abstract
The management of water resources has driven research, which seeks alternatives to know the processes occurring in river basins. Therefore, the objective of this study was to apply the SWAT (Soil & Water Assessment Tool) model as a complementary tool for the management of water resources, evaluating the Apeu river basinwith the intention of predicting through the model how different actions related to land use and management practices may influence the useful life of the river basin. The results were satisfactory, with Nash-Sutcliffe (NSE) values of 0.89% and R² of 0.99, demonstrating the significance of the SWAT model for the planning and maintenance of water resources.
Highlights
O gerenciamento dos recursos hídricos tem impulsionado pesquisas, que buscam alternativas de conhecimento dos processos ocorridos em bacias hidrográficas
The water resources management has driven researches, which search for alternatives to the understanding about processes occurring in river basins
The model was used in Apeú River Basin, from 2009 to 2017 to obtain information on the hydrological cycle dynamics based on climatic variables, type and land use
Summary
Área de Estudo A bacia hidrográfica do rio Apeú, faz parte do conjunto de sub-bacias do Rio Guamá, localizada no nordeste do estado do Pará, na mesorregião metropolitana de Belém. A Sub-bacia se estende entre as coordenadas, 1o13’10” e 1o27’37” de latitude Sul e 48o04’42” e 47o53’30” de longitude Oeste, com área de aproximadamente 307 km, pertences aos Municípios de Castanhal, Santa Izabel do Pará e Inhangapi (Figura 1). O Clima regional é do tipo Ami, de acordo com a classificação de Koppen, as temperaturas máximas e mínimas são 35° e 18° C, respectivamente, com temperatura média anual de 26° C. A umidade relativa média e chuva anual são de 80% e 2.571,6 mm, respectivamente (TENÓRIO et al, 1999; SOUZA, 2017)
