Water Resources Surface Water Software: Full Equations (FEQ) Model Web Resources
Point time-series files (PTSF's) are now read and written as direct-access unformatted. This change allows these files to move among various operating systems and compiled executables. This has been tested on five different compilers (two under Linux and three under MS Windows). PTSF's created with earlier versions of FEQ must be converted using the PTSFUTL utility or the models that generated the PTSFUTL must be rerun with FEQ version 10.20 or later.
Diffuse time-series files (DTSF's) are now read by FEQ as direct-access unformatted. This change was made to allow these files to move among the various operating systems and compilers, similarly to the PSTF's. Old files must be converted using the version of TSFUTL included in the FEQ 10.60 release package. HSPF 12.0 allows a direct output to the new unformatted DTSF using the PLTGEN routine.
The GETIC and PUTIC files have been updated to be written and read using direct access statements. This means that old forms of these files cannot be used with this version. The files have been expanded to support additional control structures as well, so old files are obselete for that reason as well.Side weir optional table definition change
The definition of the flow-factor adjustment table in the side-weir instruction, code=14, when it appears with a crest level adjustment table is changed. When both optional tables are present, FEQ does the following:
Q = fac*Q1 + (1 - fac)*Q2
The obsolete BRIDGE routine is no longer available. Function tables for bridges (table type 14) are computed using the WSPROQZ command documented in Franz and Melching (1997) with additional notes accessible using the FEQ Web Resources search utility
