Known bug in side-weir routine
Point Flow Block has been replaced
Starting with version 8.92 dated 1997/06/18, point inflows to
internal nodes (within branches) are no longer supported. Inflows to
a reach that are limited to a point should be implemented by
subdividing the reach to create a junction. The inflow is then input
as a boundary condition
(Code 6)
at the upstream node of a dummy branch
(Code 15).
Selection of the following options preceded by a binary icon retrieves a compressed UNIX tar file or a self-extracting DOS executable. A README file containing installation instructions is included with each of the software distribution files. There are separate README files for the UNIX and DOS distributions.
The Free Software Foundation's gunzip
is necessary to uncompress the UNIX tar files available below.
However, some World Wide Web browsers automatically uncompress retrieved
files. Thus, running gunzip
as stated in the installation instructions
may be unnecessary.
