Please refer to the manual for further information or for a description of tools outside the scope of this tutorial.В The manual has also been adapted using an exercise by V.В Merwade, Purdue Univ. The following steps are based on Chapter 3 of the manual provided by HEC-RAS (accessible through Help в†’Users ManualВ Supplement). These elements are now created in the RAS Mapper component of HEC-RAS. To create all necessary geometric data for HEC-RAS geometry file, before version 5.0.4, it was necessary to perform pre-processing of available data using HEC-GeoRASВ plugin in ArcGIS. This is stored in a dedicated geometry fileВ (.g0*). The geometry in HEC-RAS contains information on cross-sections, hydraulic structures, river banks, roughness coefficient, etc. Output (used to create graphs and tables) A project consists of multiple files with multiple file extensions. In order to start the tutorial, you need to be familiar with the HEC-RAS modelling system.ДЄ model in HEC-RAS is called project. Therefore, it is only possible to follow this tutorial using that version. IMPORTANT!В In this tutorial, functionalities that have only been added to HEC-RAS in version 5.0.4 are used. However, we are using the same data, transformed into meters. With the introduction of HEC-RAS 5.0.4, there is no need for using ArcGIS and HEC-GeoRAS, therefore the steps in this tutorial are significantly different. Remark:В The link above also provides a step-by-step procedure on flood inundation mapping using HEC-GeoRASВ and ArcGIS. Baxter river data is based on the materials of Purdue University that are available at: The river for which the tutorial is carried out is called Baxter and located inВ the United States of America. evaluating the quality of modelВ results.identifying the important areas that are inundated in order to help decision makers to take action that would mitigate the effect of floods or to implement adaptation measures to avoid similar floods in the future, ifВ possible.Mapping the results of a hydrodynamic model to determine the inundated areas is important in order for: The goal of this Flood Hazard Mapping Recommended PracticeВ is to evaluate the possible inundation extent in a river reach using the basic functions of RAS Mapper in HEC-RAS to create a 1D model of a river system. Step 7 - Mapping inundated areas in HEC-RAS
