HEC-RAS to MIKE11
This tool helps to convert a HEC-RAS model into a MIKE11 model. This specifically allows the conversion of a HEC-RAS geometry (*.g00) file into corresponding MIKE11 network (nwk11) and cross section (xns11) files.
This conversion tool may be extremely helpful to perform the most tedious parts of the process, while reducing the chances of human error during the alternative time-consuming manual conversion. However, this is only a first stab at the procedure to get an equivalent MIKE11 model, since further manual adjustments are necessary.
The user must first specify the geometry file, and then it is possible to customize the arrangements of Rivers and Reaches as well as the coordinate conversion. The execution creates corresponding MIKE11 files for the network (nwk11) and cross section raw data. The last text file needs to be imported into an empty binary xns11 file.
The free version allows the user to use the geometry files in the “unsteady examples” folder as distributed in HEC-RAS 4.1, and in the “1D Unsteady Flow Hydraulics” folder as distributed in HEC-RAS 5.0
This tool requires the geometry file generated in the HEC-RAS versions 4.1 or 5.0. It has been tested successfully up to version 5.0.5. It is not necessary to have MIKE ZERO installed to run the tool.
Example of use
The screens shown below can be obtained by processing the geometry file “3Reach_with_Lat.g01” provided with the HEC-RAS 4.1 installation under unsteady examples. The first two screens show the tool being executed in this case. After the execution, the raw file was converted into a binary xns11 file, and a sim11 file was created to link the nwk11 and the xns11 files. The last two screens show a visual comparison of the HEC-RAS and the converted MIKE11 models.
