H13D:
Isotopic Tools to Assess Human Impacts on Large River Systems

Submit an Abstract to this Session

Session Title - en français: Outils isotopiques pour caractériser les impacts anthropiques sur les grands fleuves

Session ID#: 6019

Session Description:
Most large river systems in the world are being impacted by human activities. Such activities include, but are not restricted to deforestation, waste water discharge, damming & flooding, agricultural intensification, etc. In order to mitigate these impacts, we need tools to assess the source of such disturbance in order to decipher natural from anthropogenic influences (as well as untangle different anthropogenic activities). This session will focus on the use of isotopic tracer techniques in studies trying to assess human impacts on large rivers systems. We encourage all isotopic systems (traditional & non—traditional stable, radiogenic, cosmogenic and noble gases isotopes) in water, nutrients and sediments.
