Abstract

The purpose of this study was to quantify the river-aquifer interaction in a hydrographic basin using the infiltrometer for seepage meter and observation wells situated on the riverbanks. The Onça stream (São Paulo State, Brazil) was chosen for this study because its location in the recharge area of the Guarany Aquifer Region. Infiltrometers were placed in three sections at the bed of Onça stream. Analyzing the behavior of the river-aquifer interaction during seven months, it was found that the average exfiltration rate was of the order of 300 mm.dia-1 in the seepage area. Further, the seepage rate was influenced by rainfall events, atmospheric pressure and rate of rise or fall of river stage. In view of the satisfactory experimental results obtained in this study, the use of infiltrometers for the determination of the river-aquifer interaction represents procedure if criterion was taken in its installation in the river bed.
