چکیده
Estudos sobre o nível subterrâneo de altas a baixas altitudes na região amazônica, em ambientes naturais, quanto à densidade do fluxo base, são conhecimentos incipientes e não refletem sua relevância atual relacionada dinâmica da água diferentes níveis topográficos. O objetivo deste trabalho foi analisar comportamento interanual lençol freático área platô, encosta baixio obter condutividade hidráulica zona saturada para estimar base local. estudo compôs-se reserva Biológica Cuieiras Amazônia Central. A metodologia consistiu coleta dados hidrológicos uso técnica Slug test piezômetros determinar saturada. resultado demostrou valores médios com variação 30mm/h mínima máxima 1177 mm/h. No freático, ao longo dos anos 2002 2022, apresentou predisposição às oscilações uma frequência 0.10 m 0.60 m; vertente 3 5 no platô 23 42 relação superfície solo. médio obtido 3,62E-06 m³/s, houve sazonal significativa período observado entre 2019. Considera-se importante explorar esse caracterização trabalhos complementares que envolvam trasmissividade, rebaixamento recarga aquífero livres consoante sequências topográficas região. pesquisa contribuiu novas informações hidrogeológicas, ajudam compreender os processos determinada área.Palavras-chave: Variabilidade espaço-temporal velocidade subterrânea. Study of Water Flow Behavior in Saturated Zone - Biological Reserve, Central AmazonA B S T R C TUnderground flow studies from high to low the Amazon region, natural environments, regarding density, are incipient knowledge and not reflect your current conversation related water dynamics at different topographic levels. The objective this work was analyze behavior table level plateau, slope lowland areas obtain hydraulic conductivity saturated zone estimate local flow. study carried out Reserve Amazon, north city Manaus. methodology consisted collecting hydrological data using “slug test” technique piezometers determine conductivity. result demonstrates average values with minimum maximum variation Over years, shallows, level, there predisposition frequency on plateau deep. obtained 3.62E-06 significant seasonal observed period 2003 It is considered important explore characterization complementary works involving transmissivity, underground solute transport free aquifer recharge according sequences region. contributed new hydrogeological information, which helps understand processes given area.Keywords: Spatiotemporal variability, groundwater velocity.
