Abstract

Groundwater monitoring is an important tool for water resources planning. The way of how groundwater levels respond to precipitation events that govern groundwater recharge can vary according to soil management and land use. Groundwater use planning is not always included in water management plans, either for lack of studies about aquifer system dynamics or effective strategies for monitoring of the reserves. The present work aims to apply models based on groundwater monitoring data for understanding the processes that occur during the hydrologic cycle and affect the availability of groundwater resources of the Bauru Aquifer System (BAS), one of the major groundwater sources available in the Médio Paranapanema region. The study area is located inside the Assis Ecological Station, where levels of BAS are monitored in 08 wells (piezometers) installed under different land uses according to forest species. Through models based in impulse response functions, it is intended to characterize the availability of water resources in areas affected by seasonal variations and the forest crops, and infer about the BAS groundwater levels dynamics, understanding the recharge processes in the Adamantina Formation, in the municipality of Assisi (SP) - Brazil.
