Reach Data File (*.rch)
The Reach Data file is used to summarize diversion comparison, well comparison, and Consumptive Use reports
by reach when the Report option (
-report) is specified. To eliminate the need to build a Reach Data file, a
preliminary one (*.xrh) is generated by the check option (
-check) for every diversion and well in the system.
This preliminary Reach Data file contains two main components: Reach Data and Node Data. The following are noted:
- Reach data is used to define how one stream reach is connected to another.
- Node data is used to assigned a stream (river) node to a stream reach.
- The default name for the preliminary file created by the check option is *.xrh. This preliminary file is commonly revised in an editor to reassign the Reach Data connectivity. In addition sub reaches may be defined to represent structures not bounded by a stream gage. After editing the Reach Data file is typically renamed to *.rch to avoid it being overwritten every time a new check run is made.
- If a river gage (*.rig) file is provided it is used by the Check option to define stream reaches. If one is not provided the Check optin uses data in the historic stream file (*.rih) to identify stream reaches. As described, this preliminary definition of steram reaches may be redefined by the user in an editor.
- The file format is free. Therefore names like My Name should be entered as a single string with a hyphen (e.g. My_Name) or enclosed in double quotes (e.g. “My Name”).
