Manning's n values and infiltration rates:
The system adjusts parameters such as infiltration and surface roughness (Manning’s n) based on the land cover resulting from interventions. This approach reflects how vegetation and soil structure influence runoff and water retention. As a result, flood simulations accurately represent the hydrological benefits of NbS.
Show moreCalibration in flood models.:
Calibration is the process of adjusting model parameters so that simulations accurately reflect actual flood behavior in a specific region. Without this adjustment, results may be unreliable, showing incorrect extents or depths, affecting decision making. FastFlood uses observed global data (water extent and flows) and applies automatic calibration globally, generating adjusted parameters that are automatically downloaded for the selected region.
Show moreWaterProof Flood Mitigation:
The WaterProof Flood Mitigation Module enables users to assess the impact of Nature-based Solutions (NbS) on reducing flood risk. It provides hydrological simulations to compare scenarios before and after NbS implementation, calculates economic benefits and Return on Investment (ROI), and visualizes results through maps and charts. This tool supports strategic prioritization and informed decision-making for sustainable water management.
