Quantifying the effect of overland flow on Escherichia coli pulses during floods: use of a tracer-based approach in an erosion-prone tropical catchment


Understory limits surface runoff and soil loss in teak tree plantations of northern Lao PDR

Many mountainous regions of the humid tropics experience serious soil erosion following rapid changes in land use. In northern Lao PDR, the replacement of traditional crops by tree plantations, such as teak trees, has led to a dramatic increase in floods and soil loss and to the degradation of basic soil ecosystem services. In this […]


Surface and sub-surface flow estimation at high temporal resolution using deep neural networks

Recent intensification in climate change have resulted in the rise of hydrological extreme events. Hydrological processes modelling at high temporal resolution is required to better understand flow patterns at catchment scale. A physically-based model called Hydrological Simulated Program-FORTRAN and two deep learning-based models were implemented to model surface runoff and sub-surface flow in the tropical […]


Discovery of a new open-air Hoabinhian site in Luang Prabang province (Lao PDR). Dating and technological study of the lithic assemblage

The Hoabinhian is a distinctive lithic techno-complex of mainland and Island Southeast Asia. Knowledge of its relationships with key patterns of technological change at a global scale has progressed over the last two decades. However, our understanding of the Hoabinhian as an indicator of evolution during Prehistory can be substantially enhanced by examiningits regional and […]


Building the information system of the French Critical Zone Observatories network: Theia/OZCAR-IS

The French Critical Zone research infrastructure, OZCAR-RI, gathers 20 long-term observatories monitoring and sampling various compartments of the critical zone. Each observatory developed its own data management and distribution systems. The paper presents the common information system Theia/OZCAR IS that was built to make in situ observation FAIR (findable, accessible, interoperable, reusable). Within M-TROPICS, Norbert […]


Nicolas Gallion has just started his M2 internship at GET within the M-TROPICS/MSEC CZO

Nicolas has been studying environmental sciences for 5 years. As part of his second year of Master’s degree at the University of Burgundy (MASTER II Soil, Water, Environment), he has the opportunity to carry out a six-month internship in collaboration with SNO M-TROPICS / MSEC in the north of Laos. His internship is part of […]


Geophysical field campaign in India

A team of geophysical scientists from iEES Paris, METIS, and GEOPS, in collaboration with the Indian Institute of Science (Bangalore) and the Indo French Cell for Water Sciences (LMI CEFIRSE) performed a field campaign in the agricultural catchment of Berambadi in November 2019. The objective was to characterize the spatial heterogeneity of regolith properties by […]


Indo-French remote sensing fall school at IISc Bangalore

An Indo-French fall school was organized from October 28 to 30, 2019, at Indian Institute of Science (Bangalore). It gathered about 50 attendees (PhD students, researchers, engineers). THEIA, the Indian Institute of Science, and the CEFIRSE (Nicolas  Baghdadi, Sekhar Muddu, Mehrez Zribi) lead the event organization. The main objective was to present different applications of […]
