Modelling Moisture Recycling in the Sudd Wetland Using WAM-2layers for Sustainable Water Resource Management and Climate Resilience

This research provides the first detailed quantification of atmospheric moisture recycling in the Sudd Wetland, a globally significant yet understudied hydrological system. By integrating ERA5 reanalysis with the WAM-2layers model, it reveals the wetland’s substantial role in sustaining regional precipitation and its vulnerability to climate and land-use changes. The methodology offers a transferable framework for assessing land-atmosphere feedbacks in data-scarce regions, directly supporting sustainable water management, climate resilience planning, and transboundary governance in the Nile Basin and beyond.
