Introduction
Note: The Delft-FEWS HEC-RAS adapter is maintained by RMA.
The conceptual solution for the interface between HEC-RAS and FEWS has been illustrated in Figure 1. Two modes of working are identified that each support a basic use case. The modes of working are:

Interface between FEWS and HEC-RAS
The FEWS Adapter for HEC-RAS forms the interface between the FEWS Forecasting Shell and the HEC-RAS model. The adapter accepts the The FEWS Adapter for HEC-RAS forms the interface between the FEWS Forecasting Shell and the HEC-RAS model. The adapter accepts the request from the Forecasting Shell to run HEC-RAS, and imports the required data provided by the Forecasting Shell.
...
A schematic representation of the communication between the Forecasting Shell and the HEC-RAS model via the FEWS Adapter is shown in the diagram below.
Figure 2 Data flows involved during run of HEC-RAS model FEWS adapter
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.
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 *.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 the output time series from the RAS DSS and 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 |
ID Mapping
The location parameters used in FEWS can be coupled to HEC-RAS DSS path names through ID-mapping. The configuration files for ID-mapping should be created separately for each HEC-RAS model. Please consult 08 Mapping Id's flags and units for more information on how to configure id mapping in FEWS system.
...
Note that only binary and configuration files relevant to the HEC-RAS adapter are included, in a real configuration a lot more files can be involved used by another modules of the FEWS system.

List of output variables is defined under outputTimeSeriesParametersFilter item uses and outputLongtitudionalProfileParametersFilter items use Regular Expressions. In most cases it is a list of variable names delimited with '|' character and for those variables where name can occur in another variable names (e.g. FLOW and FLOW AT GATE) it is necessary to use ^ as a prefix and $ $$ as a suffix of the variable.

The HEC-RAS adapter is configured properly and forecast is performed from the Delft-FEWS system - a list of input and output variables will be written into the standard log file of the system. The location and variables are based on the active <region>.b01 file of the HEC-RAS model configured in the GUI of HEC-RAS. Pre-adapter of the HEC-RAS will provide list of all possible input variables and locations in the following part of the log file:

Locations and variables listed after the line Found input at locations: can be configured in the Delft-FEWS as a part of adapter input, e.g. input.xml in this case may contain something like the lines below:

Running model from FEWS
Beste Practise Considerations
The HEC-RAS adapter requires quite some synergy between FEWS, Java and the actual HEC-RAS software versions. While a FEWS General Adapter config that uses embedded Java adapters is technically preferred above a custom JRE, it very sensitive to any software update. From past implementations we experience that using old models that run with older RAS versions, do not run anymore with actual adapter and Java versions. Therefore from an organizational and robustness perspective, it is preferred to have your both softwares as independent as possible, so with a custom JRE.
So instead of using the below default config:
Code Block | ||||
---|---|---|---|---|
| ||||
<executeActivity>
<command>
<className>nl.wldelft.fews.adapter.hec.HecRasAdapter</className>
<binDir>$HECRASBINDIR$</binDir>
</command>
<arguments>
<argument>%ROOT_DIR%/run_info.xml</argument>
</arguments>
<timeOut>3600000</timeOut>
</executeActivity>
|
one can better use a config like:
Code Block | ||||
---|---|---|---|---|
| ||||
<executeActivity>
<command>
<className>nl.wldelft.fews.adapter.hec.HecRasAdapter</className>
<binDir>$HECRASBINDIR$</binDir>
<!-- use old Java 8, while 2023.02 uses 11-->
<customJreDir>$CUSTOMJRE_64B_DIR$</customJreDir>
<!-- in case of custom JRE, pass correct default Parser definition-->
<jvmArg>-Dorg.xml.sax.parser=com.sun.org.apache.xerces.internal.parsers.SAXParser</jvmArg>
</command>
<arguments>
<argument>%ROOT_DIR%/run_info.xml</argument>
</arguments>
<console>
<!-- dump console in txt file, so in case of a crash, you see what happend-->
<redirectToLogFile>%ROOT_DIR%/log/adapter_console_logging.txt</redirectToLogFile>
</console>
<timeOut>3600000</timeOut>
</executeActivity>
