Introduction
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:
...
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 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 $ $$ as a suffix of the variable. For example: | Code Block |
|---|
|
<string key="outputTimeSeriesParametersFilter" value="^STAGE$^STAGE$$|^FLOW$^FLOW$$|Hydr Radius R|Hydr Radius L|^Flow Area$Area$$" />

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:
| Code Block |
|---|
...
156 [main] INFO nl.wldelft.fews.adapter.hec.HecRasDataAccessFacadeImpl - Found input at locations:
156 [main] INFO nl.wldelft.fews.adapter.hec.HecRasDataAccessFacadeImpl - CT River, R1, 334752.0, Flow Hydrograph
156 [main] INFO nl.wldelft.fews.adapter.hec.HecRasDataAccessFacadeImpl - CT River, R1, 0.00, Stage Hydrograph
...
|
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:
