Trade-Offs in Constraining Evapotranspiration Estimates in Complex Landscapes Using a Tracer-Aided Ecohydrological Model

Hanwu Zheng; Doerthe Tetzlaff; Christian Birkel; Songjun Wu; Christian Marx; Tobias Goldhammer; Chris Soulsby

ET interacts with multiple hydrological processes: groundwater recharge, lateral flow and streamflow. The inter-linkages become increasingly complex in ET-dominated regions with intensive management. We showed how tracer-aided modelling captures ET dynamics and how trade-offs between discharge and other observations are reflected in simulated hydrological flux/storage patterns.

Exploring impacts of forest management strategies on water partitioning in a drought-sensitive catchment using a tracer-aided ecohydrological framework

Cong Jiang; Doerthe Tetzlaff; Songjun Wu; Christian Birkel; Hjalmar Laudon; Chris Soulsby

The authors developed a parsimonious, tracer-aided forest management scenario framework using an ecohydrological model, which was designed to isolate the dominant vegetation-structural controls on long-term water partitioning. Evapotranspiration was highest under conifers, exceeding broadleaf forests and agroforestry by 7 % and 11 %. Agroforestry exhibited the greatest groundwater recharge.
