Isotopes and Isoscapes: Tools for Testing Hydrological and Biogeochemical Models

Explore the critical role of isotopes and isoscapes in hydrological and biogeochemical modeling through this informative lecture from the 2014 AGU Fall Meeting. Delve into the importance of high-quality water resources and discover new approaches for identifying contaminant sources and ages, as well as understanding complex hydrologic systems. Learn how stable isotopic compositions and their spatial and temporal distributions (isoscapes) can effectively assess the impacts of land use and biogeochemical processes on water resources. Examine the evolution of isotope hydrology over the past 40+ years, highlighting recent research developments and potential future directions. Gain insights into how isotopes and isoscapes can enhance monitoring and assessment programs aimed at quantifying and mitigating environmental alterations caused by human activities.
