Surface / groundwater interactions – a biological and ecohydrological approach
The hyporheic zone is the subsurface flow area beneath and adjacent to streams and rivers characterized by active vertical and lateral exchanges of nutrients and organic matter among surface and groundwater, in response to variations in discharge and bed topography and porosity. Current projects of the Groundwater Ecology group aims to: i) assess structure and dynamics of hyporheic communities from rivers and streams in the Mediterranean and Arctic regions; ii) investigate the role of the hyporheic zone as an intermediary transfer area of pollutants from the surface rivers to groundwater; and iii) delineate the lateral and vertical spatial extents of the hyporheic zone, characterize the streambed architecture and provide detailed spatial information on vertical and horizontal continuity of hyporheic zone. We combine the biological assessments of hyporheic invertebrate’s community’s structural patterns and ecological features with the non-invasive geophysical techniques obtained by electrical resistivity tomography (ERT).
We aims to highlight the use of hyporheic communities as an alternative proxy to investigate the water quality and surface water/ground water exchanges; to understand the hyporheic structure and function and its relation to the associated alluvial aquifers; and to provide an early warning signal of subsurface ecosystems quality decline. Our researches propose to advance our understanding of the ecohydrological processes occurring at the surface/groundwater interface and will endorse the effective incorporation of the hyporheic zone in stream management plans. Both facets are essential for the development of sustainable integrated water management strategies at the river basin level.
