Main research interests:

• Hydrology and Biogeochemistry of river basins

• Biogeochemistry of the carbon cycle

• Heavy metal transfer dynamic in soils and river systems, and interactions with biological organisms

• Pesticide and nutrient transfer dynamic in small catchments and in in large river basins

Jean-Luc PROBST has a good expertise on hydrology and biogeochemistry of small catchments and large river basins and he already worked on river systems all around the world with scientists of different countries: Congo and Ubangui, Niger, Nyong in South Cameroun, Senegal, Niger and its tributaries, Milo in Guinea, Haho and Zio in Togo, Oued Sebou in Morocco, Nahr Ibrahim in Lebanon, Amazon and its tributaries, Parana and Uruguay, Patagonian rivers, Indian rivers, Chinese rivers, Piracicaba and Tiete in Brazil, Garonne, Mosel, Rhone, Tet and Ill in France. 

Hydrology and Biogeochemistry of river basins            

        The main objective of this research is to estimate the physical and chemical erosion rates of the river basins and to determine the soil weathering type using the fluvial transport of particulate and dissolved elements. It is also to modelize the riverine transports and the rock/soil weathering using the different controlling factors such as vegetation and cultures, soil and lithology, hydrology and climate, relief… One of the key question today with the population increase is what is the impact of the anthropogenic activities, particularly the agriculture, on soil weathering rate, river water and  sediment quality and riverine transports into the oceans ?. 

         The main research themes can be summarized as follows:

> Biogeochemistry of river water and sediments, geochemical modeling 

> Fluvial transports of dissolved and particulate matters, role of the storm runoff events

> Physical and chemical erosion rate at the scale of river basin, from small catchments until large river basin and to the global scale

> Impacts of climatic change and anthropogenic activities on weathering rate and fluvial transports

> Hydroclimatic fluctuations of large river basins using the discharge variations during the last century

Biogeochemistry of the carbon cycle

         The main objective is to quantify and to modelize the role of rock/soil chemical weathering and of riverine alkalinity transports into the oceans to the global carbon cycle, particularly to the atmospheric CO2 content. It is also to determine the interactions with regional and global hydroclimatic changes. This research is based on the dissolved and particulate fluvial transport measurements of organic and inorganic carbon. Geochemical modelling, major and trace elements, strontium (87Sr/86Sr) and carbon isotopes (13C/12C) are used to estimate the weathering contribution of the different rock types to the riverine alkalinity, particularly the contribution of silicate weathering and carbonate dissolution. Concerning the riverine organic carbon (dissolved and particulate), the main objective is to determine the different sources (soil organic matter erosion, phytoplankton production and domestic effluents) and their biogeochemical interactions with the inorganic carbon fluxes. It is also to study their behaviour along the main channel during the fluvial transport.

         The main research themes are the following:

> Contribution of atmospheric/soil CO2 consumed by rock weathering and riverine transport of alkalinity into the oceans to the atmospheric CO2 content

> Role of the different factors (vegetation, lithology, runoff and temperature, relief…) on the CO2 weathering flux and on the riverine carbon transports

> Isotopic tracing (δ13C) of riverine dissolved inorganic carbon: contribution of the different sources (atmospheric/soil CO2, soil and riverine organic carbon oxidation, carbonate dissolution) and transfer mechanisms.

> Impacts of anthropogenic activities, particularly N-fertilizer spreading, on weathering CO2 consumption and riverine alkalinity.

> Riverine transfer dynamic of particulate and dissolved organic matters: role of the dams and of the anthropogenic effluents. Relationships between the organic carbon contents and the specific surface areas of the sediments. 

Heavy metal transfer dynamic in soil and river systems, and interactions with biological organisms

       The main objective is to estimate the contribution of rock/soil chemical weathering and of anthrogenic activities to heavy metal contents and dynamic  in soils and  rivers  (water and sediments). It is also to determine the role of the different controlling factors: organic carbon content, iron oxides, clay content, pH, redox potential, inorganic ligands, chemical and physical speciation… These researches are developped on small experimental catchments ( Montoussé and Hay) as well as on large river basins and they concerned heavy polluted catchments like in industrialized areas, as well as low anthropogenic pressure basins like in agricultural areas. The interactions with the biological organisms and particularly the ecotoxicological impact of heavy metals are studied in collaboration with the EcoLab Group of Ecotoxicology.  

         The main research themes are the following:

> Contribution of rock weathering to heavy metal content in soil, river water and riverine sediments: estimation of the natural geochemical background

>  Factors controlling heavy metal distribution and dynamic in soil profiles and in river systems

>  Partitioning of heavy metal between dissolved and particulate phases

>  Distribution of heavy  metal between residual and non residual phases using chemical sequential extraction

>  Contribution of anthropogenic activities to heavy metal pollution in soils and river systems: calculation of the enrichment factor

>  Lead stable isotopes (204Pb, 206Pb, 207Pb, 208Pb) tracing to determine the different Pb sources and the fractionation into the different phases (residual and non residual)

>  Rare Earth Element (REE) distribution in soils, riverine sediments and biological organisms: fractionation during the different  transfers   

Pesticide transfer dynamic in small catchments and in large river basins

        The main objective of this research recently developped is to determine the role of the storm runoff events in the transfer of pesticides from the soils to the river systems (water and sediments) in two small agricultural experimental catchments. It is also to determine the contribution of the different runoffs (surface runoff, subsurface and groundwater flows) to the exportation of pesticides by the river. At the scale of large river basins, the main objective is to determine the different pesticide sources (agriculture, urban activities), to follow the behaviour of the different molecules along the main fluvial channel and to determine their impact on the biological organisms in collaboration with the EcoLab group of  Ecotoxicology.

Teaching - Courses :

Director of a Master (2005-2009)

He was also in charge during five year (2005-2009) of the MASTER "Functioning of Ecosystems and Anthropisation" (today Ecology and Biosciences of Environment, EBEN), a joint MASTER ( Research and Professional) University of Toulouse III (UPS) - Toulouse Institute of Technology (INPT)

IAEA Expert since 2018

He is since 2018 an IAEA expert (International Atomic Energy Agency) for special service to provide the national team with a hands-on training in the domain of environmental isotope hydrology (specifically covering the areas of rain water, soil and vegetation, surface waters, groundwaters, and rock weathering). This include lectures, bibliographic research and presentation by the national team, field experiments, and a laboratory visit. The expert will assist in the development of an Applied Nuclear Science and Technology in the Environment core module for a postgraduate certificate in applied nuclear science. The first IAEA training course was given in Reduit, Mauritius at the University of Mauritius (UoM) during the period 26 to 29 November 2018. Thirteen persons have participated to the trainaing course, of which 9 UoM scientists from 3 different faculties (Engineering, Science and Agriculture), 3 from different Ministries (Environment, Agriculture, Public Utilities) and 1 from a private Company (MSIRI).
