SWAT+ Input Datasets for Assessing Wildfire, Deforestation, and Climate Variability Impacts on Water Resources in the Betsiboka Basin and Ankarafantsika National Park, Madagascar

This dataset provides input data for the SWAT+ model to assess the impacts of wildfire, deforestation, and climate variability on water resources in the Betsiboka Basin and Ankarafantsika National Park, Madagascar. It includes basin shapefiles, a Digital Elevation Model (DEM), and soil data used for watershed delineation and HRU definition. Land use data were derived from ESRI and Dynamic World products for the period 2017–2024, capturing land cover change and disturbance dynamics. Hydrological evaluation was supported using remote sensing–based discharge data. Monthly discharge for the Betsiboka Basin was obtained from GRDC-RSEG (1984–2020), while daily discharge for Ankarafantsika was sourced from GRADES-hydroDL (1980–2025). The dataset also includes SWAT+ Editor text files for implementing wildfire disturbance and recovery scenarios. Required decision-table files (scen_dtl.upd, scen_lu.dtl, lum.dtl, landuse.lum, and fire.ops) are provided to ensure consistent execution of land use scenarios. This dataset supports reproducible, scenario-based hydrological modeling in data-scarce regions.
