SWAT+ model Input data for assessing the impacts of wildfire, deforestation, and climate variability in 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 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 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. Daily discharge used to calibrate the streamflow in Ankarafantsika  was obtained 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.
