FloodRiskSwatPlus is a QGIS plugin designed to assess flood risk impacts in economic terms using SWAT+ model scenarios. It allows users to analyze potential land management changes and climate change projections, helping with flood risk management and adaptation planning.
✔️ Estimates Expected Annual Damage (EAD) at different administrative levels
✔️ Uses flood damage maps (currency/m²) for up to five return periods
✔️ Supports multiple SWAT+ scenarios for comparative analysis
✔️ Provides economic impact assessment for flood risk adaptation strategies
