BN14C:
Impacts of Dams on Terrestrial Flux and Biogeochemical Processes Within the Large River-Estuary Continuum II Posters


Session ID#: 28285

Session Description:
Large rivers represent the major link between continents and oceans and provide critical pathways for the delivery of particulate and dissolved terrestrial materials to the oceans. Unfortunately, most global rivers have been fragmented by dams, with more than 45,000 dams, over 15 m in height, now registered in the world. These massive engineering projects have radically changed the transport of water, terrestrial materials, and their associated biogeochemical processes across these vast global watersheds. Moreover, the downstream deltas are now in grave danger of being lost due to a lack of sediments needed to to keep up with sea-level rise, subsidence and overall coastal erosion. Understanding the dam-induced environmental consequences within the large river-estuary continuum has been a major concern for scientists, decision-makers and public over the past few decades. This session provides a venue for scientists from different disciplines to present their recent findings on terrestrial material transport and biogeochemical processes along this important hydrological pathway.
