Standardized peak runoff rates in cubic meters per second (m³/s). 2.) Standardized digital elevation model (DEM). These map were classified using the Natural Break (Jenks) method into five classes to produce the Flood Hazard Index (FHI). The index ranges from 1 (very low flood hazard intensity) to 5 (very high flood hazard intensity).
