IHABBS 3.10
Released in May, 2001
General
- Allows flow direction grid to be of different resolution than terrain layers (DEM, accumulation, etc)...
- Uses several new columns in the product table and product groups tables. The tables can be updated using the update_table.sh script. Note that once this is done, older executables may not be able to save properly.
Enhancements
- 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
- Can use the GISRS_SCRATCH_PATH environment variable to redirect temporary file creation to another directory (a local, one for example)
Bug Fixes
- Edit basin updated CWA field properly
- Query basin displays adjusted discharge coordinate, not original unadjusted
- Fixed exposed canvas callback which allows non HP X library displays to successfully select with mouse
- Looks for configuration file properly in current directory first
- Fixed a bug that vectorized internal basin depressions if mirror flow at discharge point
IHABBS 3.08
Released in November, 2000
General
- Does not launch if database not present
Bug Fixes
- Fixed sensitivity of ROR basin button
- Fixed a bug that corrupted the basin raster when delineating within a modified basin
- Leftover areas split by delineating within a basin now incorporated into subbasin as a modification.
IHABBS 3.07
Released in August, 2000
Enhancements
- Progress indicator during delineation process
- Added capability to view Land use and cover
- Added use of control- keyboard shortcuts for zoom
Bug Fixes
- Improved split basin check while editing basins
- Added check for basin splitting while delineating within a modified basin
IHABBS 3.05
Released in March, 2000
Bug Fixes
- Fixed bug during basin deletion process that returned an "object_identifier # not encountered"
IHABBS 3.03
Released in July, 1999
Enhancements
- Calculating major rivers is much faster
- Snap to river reach delineation option can be set in the config file using SNAP = Yes/No
- Move to higher accumulation delineation option can be set in the config file using MOVE = Yes/No
IHABBS 3.02
Released in July 1999
Bug Fixes
- Bug interfering with delineation by coordinate fixed.
IHABBS 3.01
Released in June, 1999
General
- Cosmetic changes to edit basin dialog
Bug Fixes
- Not properly reading in decimal coordinates now fixed.

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.
- IHABBS now looks to see if any modified basins will affect hydrographs created in Unit Hydrograph. Note that the two programs have to use the same hydrograph TABLENAME stored in the config file
Enhancements
- 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.
- Background color can be stored in the configuration file.

- Version5 format output is filtered so that adjacent line segments that are co-linear are collapsed into one line segment
- Menu item Help->Beta Version is removed
- Menu item Help->About IHABBS... displays the date and time of the last compilation in the status box
- County Warning Area is added to batch delineation input record as field #4.

Enhancements
- Added export rasters
- Forecast Group is added to basin attributes
IHABBS 1.10
Released in August, 1997
General
- Changes have been made to the database tables that renders version 1.10 incompatible with version 1.00
