Input description update for section 13.11 Output Files Block-- Output File Table, Franz and Melching, 1997a, p. 186

Section 13.11 Output Files Block--Output File Table

To RELEASE.TXT

This block supplies the names of files for FEQ to use in storing either a time series of flow or water-surface elevation at a node in the model. There are two different destinations for an output time series: a point time series file (PTSF) or the path name in a HEC DSS file. There is no convenient way to give both a file name for the DSS file and its path name on a single line of input. Therefore FEQ assumes that the character string given in the NAME field is the file name of a PTSF unless it has already encountered a HEC DSS file name given by itself on a line following the special keyword, HECDSS=. If FEQ has found such a line all character strings given under the NAME field are taken to be a path name for the current HEC DSS file name. The HEC DSS file name applies to all NAME values that follow it. To clear the HEC DSS file name give a blank as following the equal sign in HECDSS=. The keyword for HEC DSS file names must start in column 1 and must be in upper case.

Explanation:

Specifies the location and nature of information to place in a time series stored in either a Point Time Series File (PTSF) or the path name of a HEC DSS file. If the destination is a PTSF then UNIT column may be left blank as is done if the destination is a path name in a HEC DSS file. FEQ no longer uses unit numbers in this block and if they are present they are ignored. The column is retained to maintain consistency with old FEQ models. FEQ distinguishes these two cases based on the appearance of the HEC DSS file name keyword, HECDSS=, in an earlier line of input with a valid HEC DSS file name following the equal sign. This starts HEC DSS path name mode. All lines of input following the line containing the HEC DSS file name keyword are assumed to refer to path names in that DSS file. All DSS time series must have a type of INST-VAL. In either case BRAthe branch number; NODEthe node number; ITEMFLOW for output of flow and ITEMELEV for output of elevation; TYPEPNT or TYPESTAR, denotes that instantaneous values are to be output (the only ones allowed); and NAME the left justified name of the file for a PTSF or the path name of a time series in a HEC DSS. The table is terminated if the UNIT is given as negative. A null table must be present just as for the Input File Table.

If the branch number is zero the node number is expected to be an exterior node name as in the Special Output Block.

Multiple DSS files can be referenced for output. The current limit for the number of DSS files is five. Each DSS file must be referenced by the HEC DSS keyword before its path names can be referenced. Also the DSS file must be referenced in each block of input to FEQ. That is, the occurrence of the HEC DSS file name keyword in the Tributary Area Block does not apply to any other block. If the diffuse time series are stored in the same HEC DSS file as are the output series, giving the HEC DSS file name in the Tributary Area Block only applies to that block and does not carry over to the Output Files Block. The same DSS file name must be given again in the Output Files Block.
