In Arc-GIS environment, the HMS model SI unit system has been used. Based on the CN grid image, characteristics of the watershed and the drainage pattern, the sub-watershed have been divided, and their all other attributes have been filed in their center of gravity or centroid. Finally, ...
Simulation of Flood Inundation Extent by Integration of HEC-HMS, GA-based Rating Curve and Cost Distance Analysis Abstract Flood inundation modeling is crucial for analyzing floods and understanding the impact of rainfall on runoff. Traditional hydraulic models require substantial data and technical skill...

Flood modeling is a technical method that can provide precise information on the flood profile, including elements that govern flooding such as precipitation, runoff, and watershed features [19]. Flood maps are intended to provide early warnings to prevent environmental and human harm due to the ...
Furthermore, the applicability of the HEC-HMS model before and after urbanization and the parameter sensitivity are analyzed. The results can provide technical support for the HEC-HMS model application in other urbanization basins. 2. Materials and Data 2.1. Study Area Pu River (122°40′48″ ...
