In a new paper in Hydrological Processes, Mikael Gillefalk and colleagues use an isotope-aided ecohydrological model to study the effect of green spaces on the hydrology of an urban area in Berlin. Their results show that trees contribute the majority of evapotranspiration in the area and that the groundwater recharge under grass is higher compared to the rest of the domain. The study also highlights the need for improvements to ecohydrological models to capture important urban processes.
