Estimaram-se as taxas anuais de transpiração, evapotranspiração e escoamento superficial de uma bacia hidrográfica de 1,3 km2, localizada na Reserva Ducke, a 26 km de Manaus. Através dos resultados, observou-se que, do total da precipitação ocorrida, cerca de 62% são transpirados e 80,7% evapotranspirados, enquanto que o escoamento superficial foi representado por uma parcela de 19,3%.
