If DIFFUS=DSS

LINE 1

Variable: HEAD
Format: A80
Example: GAGE=/HECDSS=/PATHNAME
Explanation:
Supplies a user defined heading the description of the HEC DSS files and path names that define the time series of runoff intensities. This line must appear.

LINE 2

Variable: LINE(1:4), GAGE
Format: A4, 1X, I5
Example: GAGE= 1
Explanation:
Supplies a gage number to be associated with time series specifications to appear in subsequent input. FEQ must know a gage number before any time series location description is given. The gage numbers must be present in ascending order. GAGE must start in column 1 and be in all upper case. FEQ counts the gages as they appear in the input. Therefore, GAGE= -1 completes the definition of the relationship between gage numbers and time series of runoff intensities and must be the last line of the gage definition input.

LINE 3

Variable: LINE(1:6),LINE(8:71)
Format: A6, 1X, A64
Example: HECDSS=UPPER
Explanation:
Supplies the file name for a HEC DSS file that is the DSS to which subsequent HEC DSS path names refer. The name need not have an extension because FEQ invokes a HEC DSS system subprogram to append the correct extension. If an extension is used it must be valid for computer system being used. The name can have up to 64 characters and can include directory and subdirectory names. The same name can appear more than once in the input as needed to define the time series of runoff intensity.

LINE 4

Variable: LINE(1:80)
Format: A80
Example: /TEST/IMPERVIOUS/HOURLY LSRO/ /1HOUR/SIMULATED-INCHES/
Explanation:
Gives a HEC DSS path name for a regular interval time series with type PER-CUM that is in the HEC DSS file name given last and is to be associated with the gage number given last. The path name may contain 80 characters, the maximum permitted by the HEC DSS.

Note: Cards 2 through 4 are repeated until all gage numbers are associated with the time series of runoff intensity. GAGE= -1 is the last line of this part of the input for tributary area. Cards 5 and 6 do not exist when DIFFUS=DSS.
