Stable Isotopes in Large Scale Hydrological Applications
Measurement and modeling of the stable isotope signature of water in continental runoff provides unique information for large scale hydrological process studies and global water budget assessment. This chapter presents theory and case studies that illustrate isotopic signals relevant to understanding large scale hydrological processes. We provide examples illustrating isotopic labeling arising from isotopically varying runoff sources, open-water evaporation from lakes and wetlands, and river channel evaporation. Incorporation of isotopes in global and regional distributed runoff models may support the formal implementation of water isotopes as tools for monitoring large scale changes in continental water budgets and for model validation, but this work will require more comprehensive monitoring efforts for both surface water and meteoric precipitation isotopic composition.
