Field experiment of the ANR ATCHA project

Missions

6 June 2018

Jean Riotte (IRD-GET) and Laurent Ruiz (INRA/IRD-GET), together with M. Tripti (Post doc IISc) and Nils Dubois (M2 ISTOM), performed a field experiment within the frame of the ANR ATCHA project, aiming at assessing the fate of nitrates from irrigation by groundwater. The experiment was performed in the Berambadi catchment (M-TROPICS/BVET) on two soil types with 4 different groundwater compositions. Monitoring consisted in GHG (N2O, CO2, CH4), soil moisture and soil pore water composition.

Geophysical measurement campaign in India

A geophysical measurement campaign to characterize the spatial heterogeneity of the regolith thickness (main potential water stock in fractured aquifers) was carried out in May 2022 in both the Berambadi and the Mule Hole catchments (PI: Jean Riotte, IRD). Supported by EQUIPEX CRITEX, the campaign combined electrical resistivity, seismic, and Control Source Audio-Magneto-Telluric (CS-AMT) surveys. […]
