Invitation to seminar
Welcome to all interested in this seminar by: Visiting Professor M. Bayani Cardenas from the University of Texas Austin with the title:
Hydrobiogeochemistry of terrestrial-aquatic interfaces from pore to continental scales
Host: Anniina Kittilä, Section for Environmental Geosciences.
Abstract: The parts of a river corridor - shallow aquifers, alluvium, floodplains, and the river itself - are intricately intertwined. Many important hydrologic and biogeochemical processes take place where the parts meet, which are the sediment adjacent to and below the river called hyporheic zones, and also more broadly referred to as terrestrial-aquatic interfaces. Because of mixing of surface- and groundwater, the hydrobiogeochemical processes at terrestrial-aquatic interfaces are characterized by steep physical and chemical gradients. These processes determine water quality and ecosystem health from the scale of individual pores, to bedforms, to reaches, and eventually integrate to impact watersheds spanning continents. This presentation is a primer and a synthesis of research that explains the mechanics and chemistry of river–hyporheic–aquifer processes from millimeter to megameter scales.
