A collection of related libraries for use in hydrologic applications


The libraries and utility programs contained in LIBANNE were previously packaged as part of the LIB software distribution. Changes made in the LIBANNE code are documented in the RELEASE.TXT file distributed with LIBANNE. LIB has been divided into two separate distributions, LIBANNE and LIBHSP. LIBHSP contains the LIB libraries specific to the HSPF model.


Selection of the following options preceded by a binary icon retrieves a compressed UNIX tar file or a Windows installation program. 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.
