Abstract

River flood modelling comprises three main components as follows: hydrological modelling, hydraulic modelling and river flood visualization in a geographic information system (GIS). In this research, HEC-HMS and MIKE11 were utilized as hydrological and hydraulic models which were linked to a GIS environment using HEC-GeoHMS and MIKE11GIS extensions. In this procedure, firstly, the rainfall-runoff simulation is conducted to generate the design flood hydrographs which are used as input for the hydraulic model with boundary or initial conditions. Then, according to design hydrographs, hydraulic modelling is performed for
defined scenarios. GIS is used to visualize the results of the hydraulic model. The primary results visualized consist of flood extent and flood depth maps. These maps are the basic requirement for preparing the river flood hazard and river flood risk maps.
