• Ability to open flow direction grid as read only-- does not copy flow layer into temp file and does not allow editing of non-contributing area

• Edit basin updated CWA field properly

• Looks for configuration file properly in current directory first

IHABBS 3.0
Released in May, 1999
General

• All Export and Removing/Renaming of file functions removed. (They are now accessible from the File submenu on the NOHRSC toolbar
• IHABBS shares the nohrsc.cfg configuration file.

• More stable GUI
• User can now define up to 6 elevation zone boundaries within a basin
• Creating/modifying basin calculates mean/min/max slope, elevation, and aspect
• Query basin now has an option for "Less" or "More", where the user may view the traditional basin attributes or the expanded, which include the statistics described above
• Opening an old basin layer will update and calculate these attributes. Note that these older basin layers will need to be updated before other applications can effectively use them. (They'll receive warning messages otherwise.)
• Program can be run from the NOHRSC toolbar (for improved color management)
• IHABBS can be executed outside the directory from the NOHRSC toolbar.
