The Pays d'Auge region is known for its diversity of instability including large and deep-seated landslides. Among them, the “L'Hermitage landslide” is one of the largest historical phenomena in the Vaches Noires area of Normandy, France. As it was triggered during a period when few observations were performed, there is still considerable uncertain...

De l’emblématique Sahara aux déserts polaires, en passant par les déserts de Sonora, d’Atacama ou de Gobi, ce catalogue invite à un formidable voyage, au cœur d’une diversité de paysages insoupçonnés. Leur point commun ? L’aridité, les températures extrêmes, les vents violents… des conditions hors norme a priori hostiles à la vie. Et pourtant, il y...
Intraplate seismicity represents a notable occurrence within the stable North American Craton. This research explores the potential sources of stresses that could reactivate older faults and influence seismic activity within this region. Among these sources, the enduring impact of the last glacial period is considered, which includes continued glac...
Karstic aquifers are highly reactive and heterogeneous hydrosystems, characterized by a strong interaction between surface water and groundwater. In the Mediterranean area, rapid recharge occurs in active losses located along temporary rivers, enabling a swift flow to infiltrate deep into the groundwater reservoir. However, this recharge can also o...
Describing the structural complexity of seabeds is of primary importance for a number of geomorphological, hydrodynamical and ecological issues. Aiming to bring a decisive insight on the long-term development of a unified view, the present study reports on a comparative multi-site analysis of high resolution topography surveys in rough nearshore en...
Cette thèse combine une double approche géomorphologique et sédimentologique associée à l’utilisation de données LiDAR, bathymétriques, photogrammétrie drone et de datations radiocarbones. Elle a permis de reconstituer les paléos dynamiques glaciaires en contexte de déglaciation pour l’Inlandsis Laurentidien depuis le dernier maximum glaciaire, il ...
As urbanization continues to accelerate in response to population pressures, understanding how urban rivers change becomes increasingly important. Studies addressing sedimentological responses to urbanization have focused on sediment yield and sediment loads. Few have examined how the size distribution of particles changes with urbanization, even t...
What is groundwater? Groundwater is water that fills and moves between spaces in underground rocks, gravel, sand, or other materials.
