WAWAPiso

The WAWAPiso project (West African WAter Pathways: regional monitoring and hydrological modelling with stable ISOtopes) develops an innovative integration of isotopic tracers into eco-hydrological modelling, to investigate water cycle dynamics in the critical zone of West Africa. Leveraging the long-term data and services of the AMMA-CATCH observatory (https://www.amma-catch.org/), part of the OZCAR Research Infrastructure (https://www.ozcar-ri.org), the project sheds new light on overlooked subsurface flows in hard-rock environments and refines the quantification of catchment-scale evapotranspiration. It highlights the unique insights provided by isotopic tracers and reinforces the value of long-term monitoring for understanding regional water cycle processes and their perturbations.
