Braided rivers have been harnessed for their natural resources and modified profoundly through decades of human activity, sometimes to the point where major ongoing management issues and risks to society have arisen. Restoration is then a process that aims to return functionality to these hydrosystems, especially in order to reach good...

Modeling on changing watersheds is a particularly challenging topic for hydrologists, as land use change is not stationary and it has impacts on the rainfall-runoff relationship. It is necessary then to take into account these changes in the modeling, as well as climate change, in order to understand the hydrosystem and to improve the use of...

Braided rivers are dynamic hydrosystems characterised by a multiple channels morphology and a marked hydrology with high amplitude variations and high diversity of macro-, meso-and microhabitats: channel types, geomorphic units and flowing conditions. After the WFD publication¹ and the objective to achieve good ecological status, restoration...

Braided rivers are characterised by a multichannel pattern maintained by a dynamic hydrologic regime with alternance of floods and low water periods. In this context, the aquatic habitat mosaic displays high turnover rates. Nevertheless, benthic invertebrate communities present in these systems are adapted to these dynamic...

Les rivières en tresses sont des hydrosystèmes davantage étudiés depuis ces dernièresannées1,2. L'utilisation d'indicateurs permet de dresser un diagnostic sur ces milieux,notamment leur dynamique hydrosédimentaire. Dans un contexte actuel de restauration, denombreuses opérations sont entreprises sur ces milieux, afin d'atteindre le bon état...

The historical composition of landscapes is recognized as an important factor for explaining plant diversity, because species assemblages are not only patterned by current ecological conditions, but also represent legacies of the past. Contrary to terrestrial ecosystems, the influence of history has rarely been considered for aquatic...
