Title A name given to the resource Estabilidade temporal da potenciometria e da salinidade em vale aluvial no semiárido de Pernambuco Temporal stability of piezometric levels and salinity in an alluvial valley in the semiarid Pernambuco - Brazil Creator An entity primarily responsible for making the resource Robertson V. de P. Fontes Júnior, Abelardo A. A. Montenegro, Suzana M. G. L. Montenegro, Thais E. M. dos Santos Description An account of the resource As restrições no uso e na disponibilidade das águas subterrâneas nos aluviões do semiárido nordestino estão diretamente ligadas à sazonalidade e à variabilidade espacial de seus níveis potenciométricos e salinidade. A estabilidade temporal é de grande interesse, por facilitar o monitoramento, possibilitando se obter locais representativos acerca da área em estudo, constituindo-se em uma importante ferramenta para a gestão dos recursos hídricos subterrâneos. Com isto, o objetivo deste trabalho foi identificar áreas com estabilidade temporal do nível potenciométrico e da salinidade, em aquífero aluvial do Agreste Pernambucano. Foram utilizados o método das diferenças relativas e a validação por correlação entre a média no tempo do piezômetro estável e a média dos demais piezômetros. Quanto ao nível potenciométrico identificaram-se áreas estáveis que representam o comportamento médio enquanto para a salinidade as áreas estáveis não representam adequadamente a média do vale aluvial devido, possivelmente, às restrições de circulação hídrica e ao uso agrícola do solo.The restrictions in the use and availability of groundwater in alluvial aquifers of the northeastern semiarid are directly related to seasonal and spatial variability of piezometric levels and salinity. Temporal stability is of high interest for monitoring, allowing representative locations about the studied area to be identified, being an important tool for groundwater resources management. Thus, the objective of this work was to identify areas with temporal stability for the water table level and salinity in an alluvial aquifer in the 'Agreste' region of Pernambuco State in Brazil. The relative difference method was used and also the validation by correlation between the mean response of one stable piezometer against the mean of all other piezometers, performed in time. For the water table level, stable areas representing the mean behavior were identified, while the stable areas for salinity did not represented well the mean behavior, perhaps due to flow restriction, and also due to agricultural soil use.
