Despite their high ecological value, non-perennial streams have received less attention than their perennial counterparts. This doctoral thesis addresses this disparity by advancing knowledge on the dynamics of the drainage density and hydrologic processes ...
Aquatic vegetation in fluvial systems is often characterized by spatial patterning of the plant patches. To investigate the conditions for the formation of vegetation patches, we explore the stability of a uniform flow over a non-erodible bed with a unifor ...
Niché dans la vallée du Haut-Giffre, au pied de l’aiguille du Criou, Samoëns est un village de moyenne montagne à l’habitat dispersé. L’accroissement du tourisme y favorise l'établissement de structures principalement destinées aux vacanciers. Dans ce cont ...
In the riverine environment, the riverscape, sediment and flow regime are essential drivers for natural habitat dynamics. Today, most water courses in Europe are regulated, and their natural dynamics are impaired. Flood releases coupled with the artificial ...
Actors from academia, politics, and the civil society increasingly acknowledge that to address our current unsustainable regimes of resource and energy demand, we need to redefine our ways of being and doing. Everyday practices are a key driver of energy a ...
The Species-Area Relation (SAR), which describes the increase in the number of species S with increasing area A, is under intense scrutiny in contemporary ecology, in particular to probe its reliability in predicting the number of species going extinct as ...
In an environment subject to anthropogenic pressures, the understanding of lakes is crucial as they are essential for ecosystems and represent a source of the scarce accessible freshwater existing on Earth. Water quality management is especially designed t ...
Extreme summer drought events are predicted to increase in intensity and frequency within the current century. The resulting water scarcity could dramatically impact human activities related to agriculture, due to the strong relationship between precipitat ...
L'EPFL participe avec un atetier de projet mené par le Lab-U, sous la direction de la professeure Paola Viganò. La question de la densité sera posée à l'échelle du territoire alpin suisse dans lequel la densification croise la tradition de l'habitat dispe ...
Concurrent rehabilitation alternatives were evaluated for a 1900 m reach of the River Etsch in northern Italy using a recently developed Hydro Morphological Index of Diversity (HMID) model. HMID is a new tool enabling quantitative assessments of river rest ...
