Flood Modeling: A Comprehensive Review on IDF Curves, HEC-HMS, HEC-RAS, and GIS Integration

Abstract: Flood modeling is a critical aspect of managing the risks associated with flooding events, with recent advancements emphasizing an integrated approach. This extensive review examines the integration of Intensity-Duration-Frequency (IDF) curves, Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS), Hydrologic Engineering Center-River Analysis System (HEC-RAS), and Geographic Information Systems (GIS). This review article contributes to the understanding of challenges, advancements, and practical implications associated with the application of IDF curves, capabilities and applications of HEC-HMS, HEC-RAS and GIS in flood risk assessment. By synthesizing these methodologies, the review aims to contribute to the understanding of flood modeling techniques, supporting informed decision-making and resilient infrastructure planning.

Keywords: Intensity-Duration-Frequency (IDF) curves, Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS), Hydrologic Engineering Center-River Analysis System (HEC-RAS), and Geographic Information Systems (GIS), HEC-HMS, HEC-RAS and GIS.
