Water stable isotopes (18O and 2H) are widely used as ideal tracers to track water through
the soil and to separate evaporation from transpiration. Due to the technical developments in …

In response to increasing pressures on water resources, watershed services management
programs are implemented throughout the tropics. These programs aim to promote land …

The choice for specific parameter estimation methods is often more dependent on its
availability than its performance. We developed SPOTPY (Statistical Parameter Optimization …

Measurements of δ2H and δ18O composition of pore waters in saturated and unsaturated
soil samples are routinely performed in hydrological studies. A variety of in‐situ and lab …

We introduce EcH 2 O-iso, a new development of the physically based, fully distributed
ecohydrological model EcH 2 O where the tracking of water isotopic tracers (2 H and 18 O) …

Core Ideas Bulk soil water isotopes have an evaporation signal, but mobile water isotopes
do not. These differences are time variant and linked to the volume and age of the mobile …

The vadose zone plays a crucial role in the water cycle for storing water, providing water to
vegetation and transporting solutes or degrading contaminants. Earth scientists have long …

Increasing demands for livelihood resources in tropical rural areas have led to progressive
clearing of biodiverse natural forests. Restoration of abandoned farmlands could counter …

Few high‐elevation tropical catchments worldwide are gauged, and even fewer are studied
using combined hydrometric and isotopic data. Consequently, we lack information needed …

Quantifying soil water storage, mixing, and release via recharge, transpiration, and
evaporation is essential for a better understanding of critical zone processes. Here, we …
