The FEWS Adapter allows running of HEC-RAS by FEWS. The FEWS Adapter should be considered as a thin communication (software) layer on top the existing HEC-RAS engine. The adapter is tightly connected to the model engine. For longer term consistency, a FEWS adapter should therefore preferably be maintained by the owner of the model code, in this case HEC. The FEWS Adapter for HEC-RAS shall be developed by HEC or handed over to HEC upon completion.
Several design options for the FEWS Adapter will be discussed in this section. Red box in the diagram below outlines the components within the adapter itself. The technical options will be discussed in the next section.
The features of the are listed in the tables below.
Preprocessing 01 | Clean up work and output folder |
Preprocessing 02 | Create module diagnostics file in Published Interface (PI) format |
Preprocessing 03 | Read the time series from PI time series |
Preprocessing 04 | Convert input PI time series into RAS DSS *.b01 files |
Launcher 01 | Run HEC-RAS with run period and model alternative |
Postprocessing 01 | Open/create module diagnostics file in PI format |
Postprocessing 02 | Read a selection (output-dss-paths.txt) of the output time series in from the output RAS DSS fileand binary output files |
Postprocessing 03 | Write the time series to the output.xml |
Postprocessing 04 | Write the time series to the binary-output.xml |
Postprocessing 05 | Write the updated PI state file to export folder |
