| Zusammenfassung |
| The Meuse is an important rain-fed river in North-Western Europe. Nine
million people live in its catchment, split over five countries. Projected
changes in precipitation and temperature characteristics due to climate
change would have a significant impact on the Meuse River and its
tributaries. In this study, we focused on the impacts of climate change on
the hydrology of two sub-catchments of the Meuse in Belgium, the Lesse and
the Vesdre, placing the emphasis on the water-soil-plant continuum in order
to highlight the effects of climate change on plant growth, and water uptake
on the hydrology of two sub-catchments. These effects were studied using two
climate scenarios and a physically based distributed model, which reflects
the water-soil-plant continuum. Our results show that the vegetation will
evapotranspirate between 10 and 17 % less at the end of the century
because of water scarcity in summer, even if the root development is better
under climate change conditions. In the low scenario, the mean minimal 7
days discharge value could decrease between 19 and 24 % for a two year
return period, and between 20 and 35 % for a fifty year return period. It
will lead to rare but severe drought in rivers, with potentially huge
consequences on water quality. |
