Resumo

O uso de modelagem eco hidrológica em estudos de balanço hídrico, descarga de sedimentos e de nutrientes tem aumentado em todo o mundo. Importante na modelagem é a calibração e validação do modelo para que possa ser usado como ferramenta de estudo de mudança de cenários de uso e manejo. O objetivo deste estudo é calibrar e validar o modelo SWAT (Soil and Water Assessment Tool) e estimar os principais componentes da vazão do rio em uma bacia de planície rural. Foi investigada uma área de 462 km² da parte superior da bacia hidrográfica do rio Stör, localizada no norte da Alemanha. Os resultados da modelagem revelaram boa performance da calibração e validação da vazão diária do rio em três estações de medição da bacia Stör superior. De acordo com o modelo SWAT, os componentes da vazão são representados por 34,3% de fluxo de drenagem, 52,8% de fluxo de águas subterrâneas, de 7,7% de fluxo lateral e 5,2% de fluxo de escoamento superficial de água nesta bacia hidrográfica de planície.
