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.
