Short summary
This study was conducted on three alluvial fans located in Iran using a combination of the FAN model, the hydraulic portion of the FLO-2D model and geomorphological information. Initial stages included three steps: (a) identifying the alluvial fans' landforms, (b) determining the active and inactive areas of alluvial fans, and (c) delineating 100-year flood within these selected areas. The goal of this research was to introduce a simple but effective solution to estimate the flood hazards.
