Summary

Dams and other transversal barriers are obstacles crossing the river section and causing discontinuities for sediment and fauna. Removing them consists in destroying all the obstacles, restoring the slope and the longitudinal profile of the river, therefore allowing re-establishment of fluvial dynamics, as well as sedimentary and ecological...

Summary

An oxbow lake is an ancient meander that was cut off from the river, thus creating a small lake with a U form. Reconnecting it with the river consists in removing terrestrial lands between both water bodies, therefore favouring the overall functioning of the river by restoring lateral connectivity, diversifying flows and cleaning the river section of the present oxbow for a better water retention during floods.

Summary

According to the Convention on Wetlands (1971), a wetland is an area of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres. 

Wetlands play a crucial role in regulating the global climate and are natural biofilters for pollutant removal, nutrient...

Summary

Basins are areas for storage of surface runoff that are free from water under dry weather flow conditions. Basins are bodies of water designed to store surface runoff. They play a critical role in stormwater management by reducing flood risk and improving water quality. The performance of basins is highly site-dependent and often requires upstream source control to function effectively. There are three main types of basins: retention,...
