A significant water table lowering due to increased pumping of groundwater for domestic, irrigation and industrial demands has been observed recently in the Punata alluvial fan (Bolivia). The general objective of this research project is to understand and acquire knowledge of the hydrogeological settings in the research area; this will be done by retrieving information from the aquifer system (layering and layer thicknesses), groundwater flow patterns and recharge/discharge processes.
Geophysical methods and hydrochemistry analysis will be the main tools for studying the hydrogeological settings in the Punata alluvial fan. According to our knowledge, few geophysical surveys have been performed in alluvial fan environments; by combining the geophysical and hydrochemistry methods it is aimed to demonstrate its applicability in alluvial fans.
