Exposure Assessment Models

WhAEM2000 Release Notes

Corrections & Improvements to Prior Versions

The line-sink " " parameter is now automatically calculated by the Solver.
The Ending Head on the Linesink Properties dialog may be copied to the Starting Head for quick sequential entry of multiple line-sink strings along a stream.
The organization of the Inhomogeneity Properties Dialog has been improved.
Inhomogeneity domains can now have shared boundary sections.
The Tools menu contains a Database Repair feature to remove remote Test Points, Wells, or Text Labels that cannot be captured in the WhAEM model window (cause Zoom to Extents to fail).
Improved prompting for a new solution or just a new contour plot or path line traces in response to model parameter changes.
The View menu now has a Show Vertices option with a sub menu for Show Linesink Vertices and Show Inhomogeneity Vertices.

Known Deficiencies

WhAEM2000 does not support International representations of commas as decimal points. The work around for European users is to set Windows to use the American decimal mode in the control panels.
Users of the Windows Vista operating system must manually download and install the WinHlp32.exe executable in order to use the WhAEM2000 Help system. This is necessary, because Windows Vista does no longer support this Help system and prevents the WhAEM2000 Installer from installing it. The WinHlp32.exe may be downloaded from the Microsoft website:
- Windows Help program (WinHlp32.exe) for Windows Vista Exit

Corrections & Improvements to Prior Versions

A utility was added for editing shapefiles under View > Basemaps > Vector Graphics. The user can choose a single color or they can choose an attribute field which specifies how a particular shape file is colored. The user may also select any number of attribute fields (contained in the shape file) to display as labels.

Known Deficiencies

WhAEM2000 does not support International representations of commas as decimal points. The work around for European users is to set Windows to use the American decimal mode in the control panels.

Corrections & Improvements to Prior Versions

Raster graphics, such as USGS Digital Raster Graphics files (DRGs) in the GeoTIFF format are now supported as basemaps. A utility is available for converting USGS Digital Orthophoto Quads (DOQ) into GeoTIFF format.
Simple WHPAs are now available as a Tool. The simple WHPAs include arbitrary/calculated fixed radius, asymmetric CFR, and well in uniform flow.

Known Deficiencies

WhAEM2000 does not support International representations of commas as decimal points. The work around for European users is to set Windows to use the American decimal mode in the control panels.

Corrections & Improvements to Prior Versions

The Tools basemap browser was expanded to have Web and CD-ROM access to EPA supplied binary basemaps.
The Tools convert and export are now ESRI shapefile compatible.
The solver GFLOW1 has been updated (Oct 20, 2002).
The base map viewer has been updated to fill in blue for major surface water features, and the potential viewing of elevation values associated with hypsography BBMs has been added (although the hypso maps are currently available on the CEAM Webserver for Ohio and Nebraska only).

Known Deficiencies

WhAEM2000 does not support International representations of commas as decimal points. The work around for European users is to set Windows to use the American decimal mode in the control panels.
Convert > DM to BBM may experience an error message.
Convert > SDTS to BBM does not currently support elevation labels for 7.5 minute hypsography coverages.

Corrections & Improvements to Prior Versions

Corrections & Improvements to Prior Versions

Corrections & Improvements to Prior Versions

The conversion tool for SDTS to BBM has been updated to correct for bugs in routine SDTS2BBM.
The conversion tool for DLG to BBM has been updated to correct for bugs in routine BLDDLG.

Corrections & Improvements to Prior Versions

New solution engine GFLOW1, and therefore slightly different data entry windows.

Corrections & Improvements to Prior Versions

The conversion tool from DXF to BBM has been updated to include recent dxf and dwg formats. This tool is still not robust.
A warning is now given during creation of a project to recognize that base maps using USGS DLG, including all the bbm files downloaded from the EPA Web server, have distance units in feet, and the user should not attempt to change to feet.

Corrections & Improvements to Prior Versions

Updated WhAEM2000 GUI file conversion utility to recognize the variety of USGS DLG file formats (Tools > Convert > DLG to Basemap/SDTS to Basemap).
Updated WhAEM2000 GUI to allow for multiple selection of BBM files (Project > Base Map Settings > Add BBM).
Corrected deficiency of the WhAEM2000 GUI in recognizing project work spaces with long names or spaces in the path.

Known Deficiencies

WhAEM2000 may not fully support the most recent versions of DXF. The work around is to convert to earlier DXF formats (e.g., using TurboCAD, Surfer).
WhAEM2000 does not support International representations of commas as decimal points. The work around for European users is to set Windows to use the American decimal mode in the control panels.

Corrections & Improvements to Prior Versions

First released through CEAM on July 3, 2000, 14:03:44.
Created WhAEM model system and user support documentation files (refer to sub-directory/folder README): README.TXT, RELEASE.TXT, UPDATE.TXT, ABSTRACT.TXT, RESPONSE.TXT, and YEAR2000.TXT.

Known Deficiencies

Unhandled error will occur when adding binary base maps (BBM) to a new project under Windows95 when the project is created in the C:/Program Files/WhAEM folder. The work around is to create new projects under a different path and/or folder, for example C:/WhAEM_DAT/.
There is an incompatibility of the Tool convert DLG to BBM for some USGS maps. Work is underway to correct this problem.
