Short summary
We used a tracer-aided ecohydrological model to quantify water flux–storage–age interactions for three urban vegetation types: trees, shrub and grass. The model results showed that evapotranspiration increased in the order shrub < grass < trees during one growing season. Additionally, we could show how infiltration hotspots created by runoff from sealed onto vegetated surfaces can enhance both evapotranspiration and groundwater recharge.
