Résumé

Lake Titicaca is the largest freshwater lake in South America and is nowadays perturbed by fast changes due to an important urban growth and climate changes. Our multidisciplinary consortium proposes to carry out the first ever-made quantitative assessment of transferred water masses and eutrophication-critical nutrients (ammonium, phosphate and nitrate) from the groundwater to the lake. The combination of classical and original geophysical methods will allow reliable and cost effective mapping of aquifer boundaries and monitoring of groundwater levels and quality, especially the eutrophication-critical ions. These data will be used to calibrate a mechanistic transfer model. The implemented monitoring program and modelling task will serve as base for a 2nd summer school delivered to students and professionals, following the 1st one organized in La Paz thanks to IRD and LABEX OSUG@2020 funds. The project is half funded with one full PhD scholarship and the student travels between France and Bolivia.
