Instream Flow Station File (*.ifs)
The instream flow station file contains information to describe the physical properties of each instream flow in the system. This file is read by subroutine DATINP.
| Row-data | Variable | Description |
|---|---|---|
| Station Data | ||
| 1 | Format (a12, a24, a12, 1x, a12,1x,a12,i8) | |
| 1-1 | cifrid(1) | Instream flow station ID |
| 1-2 | xfrnam1(i,1) | Instream flow station name |
| 1-3 | cgoto(1) | Upstream river node where the instream flow point or reach is located |
| 1-4 | ifrrsw(1) | Switch; 0 = off, 1 = on |
| 1-5 | crtnid | Downstream river node where the instream flow point or reach is located. For an instream point enter cgoto(1) or leave blank |
| 1-6 | cifrridy(1) | Daily Instream station ID (for daily model only). See Section 7.17 for a detailed discussion. |
Enter Instream station ID (crunid) if daily data will be provided for this station. Monthly data controls. |
||
| Enter another instream station ID to use the daily distribution of another but weight values by the monthly total in *.rim file | ||
| Enter 0 to use the average daily value from the monthly data in the *.ifm file. Monthly data controls. | ||
| Enter 3 to use the daily value from the daily demand (*.ifd) file. Daily data controls. | ||
| Enter 4 use a daily pattern developed by connecting the midpoints of monthly data. Monthly data controls. | ||
| 1-7 | iifcom(1) | Data type switch |
| 1 = monthly total demand provided (Section 4.17) | ||
| 2 = annual total demand provided (Section 4.18) |
Repeat for the number of instream flow stations
