Última Shallow aquifer response to climate change scenarios in a small catchment in the Guarani Aquifer outcrop zone Anais da ABC (AABC) MELO,DAVI C.D.; WENDLAND,EDSON. ABSTRACT Water availability restrictions are already a reality in several countries. This issue is likely to worsen due to climate change, predicted for the upcoming decades. This study aims to estimate the impacts of climate change on groundwater system in the Guarani Aquifer outcrop zone. Global Climate Models (GCM) outputs were used as inputs to a water balance model, which produced recharge estimates for the groundwater model. Recharge was estimated across different land use types considering a control period from 2004 to 2014, and a future period from 2081 to 2099. Major changes in monthly rainfall means are expected to take place in dry seasons. Most of the analysed scenarios predict increase of more than 2 ºC in monthly mean temperatures. Comparing...

Discharge tests are conducted in order to determine aquifers transmissivity (T) and storage coefficient (S). However the interpretation of test data is not unique and the results may vary depending on adopted hypothesis. In this work, the convolution technique is applied for the reconstruction of observed drawdown curves aiming for the reduction of uncertainty. The interference between a flowing well and an observation well is evaluated in order to determine the hydrogeological parameters of the confined Guarani Aquifer System (Araujo et al. 1999). Discharge test data are analyzed according to the Jacob and Lohman (1952)method. The application of convolution enabled the determination of the most reliable solution. Obtained transmissivity (T = 411.0 m2/d)... Tipo: Info:eu-repo/semantics/article Palavras-chave: Hydrogeology; Groundwater; Transmissivity; Storage coefficient; Pumping test.
