Vegetation strongly interacts with the terrestrial water cycle and therefore influences runoff processes within vegetated catchments. A better understanding of the role of vegetation in catchment hydrology will contribute to improving both hydrological predictions, and mitigation of global change through adaptive management strategies.

This session highlights processes linked to vegetation, ecosystem dynamics, and land cover change that modify the catchment response. Some processes, such as interception, influence the total water arriving in the catchment, others influence the distribution of the water within the catchment, and thus modify slow or fast runoff
processes. In this way, vegetation might contribute to alter
baseflow or flood characteristics.

We invite papers, both measurements and modelling, that investigate the role of vegetation on terrestrial runoff processes and related feedbacks at the catchment up to continental scale. We also welcome papers related to catchment processes contributing to data assimilation and model developments leading to a better representation of vegetation dynamics.
