Global analysis of the relation between vegetation and transit times using stable water isotopes

Summary

Recent studies have demonstrated a direct relation between climate characteristics and vegetation in catchments. For example, plants appear to develop a root system that allows both optimal growth and resistance against region-specific droughts. As climatic conditions also affect the way catchments store and release water (i.e., the transit times), we expect a direct relation between vegetation and transit times. To test this hypothesis across diverse climate zone, we are creating and analysing a global dataset of water balance and stable water isotope data.
