Floriann Langlet, a master student from the Université de Toulouse III Paul Sabatier, just finished his internship at GET laboratory. He analyzed the occurrence of bacterial pathogens along the Mekong river basin (M-TROPICS/MSEC) and found that soil type, discharge, and turbidity were among the key variables associated to E. coli concentration in the rivers.
Missions
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 […]
Conferences
A poster was presented at EGU 2018 Conference by Dr. Kyung Hwa Cho, from UNIST, South Korea, about the modelling of E. coli in Houay Pano catchment (M-TROPICS/MSEC): a research work led by Minjeong Kim in collaboration with GET. The abstract is available here.

A book authored by Yves AUDA has been published, handling the analysis of the critical zone with open-source softwares GRASS and QGIS: field sampling, hydrological models, landscape analysis, remote sensing mapping, digital elevation models, etc. Theory and exercises are based on data from the M-TROPICS/MSEC CZO in Northern Laos, gathered within the TecItEasy ANR project. […]

This PhD proposal aims at better understanding the transport and fate of pathogen bacteria in tropical areas, e.g. fecal pathogens such as the Fecal Indicator Bacteria (FIB) Escherichia coli and the environmental pathogen Burkholderia pseudomallei. The methods suggested to be implemented in this PhD will be a mix of in situ observations, field and laboratory […]

An inter-disciplinary team at Bengaluru’s Indian Institute of Science (IISc) studied how different tree species partition underground water resources up to 30m depth and co-existing tree species diverge in water uptake depths (M-TROPICS/BVET). Deep rooted trees turn to be more vulnerable to severe droughts than shallow rooted species : climate change-type droughts could then affect […]

The analyses of silicon isotopes in soil, water and plant compartments of the Mule Hole forested watershed (M-TROPICS/BVET) reveal that vegetation takes up twice more silica than first estimates using elemental mass balance. This flux is 30 times higher than the solute silica flux exported by the stream, itself resulting principally from litter decay. The […]

This study (M-TROPICS/BVET) identified and quantified the Si sources to rice plants using a solute mass balance at soil-plant scale and the silicon isotopic signatures of the various Si pools. It reveals that the main Si sources are soil amorphous silica, irrigation water and to a lesser extent Si fertilizer when it was applied. In […]
