Recent and planned model enhancements include:
WinSLAMM - current version: v 9.3.1 (release date 5 July 2008)
 | Grass Swales - Added grass swale maximum velocity, depth and shear
values for each event to the grass swale event detailed output file. |
| Hydrodynamic Devices - Added hydrodynamic devices to Freeway land
use Paved Lane and Shoulder Area source areas and corrected hydrodynamic
device calculation problems when the device was defined without any inlet
flow controls. |
| Minor corrections, changes and additional error checks. See the
WinSLAMMLog.txt file for details. |
WinSLAMM - current version: v 9.3.0 (release date 21 April 2008)
| Biofilters/Infiltration Devices - Added particulate filtering
through the engineered soil. |
| Wet Detention Ponds - Added a scour reduction function to calculate
reduced settling in ponds less than three feet deep. |
| Grass Swales - Added particulate filtering in grass drainage
systems. Also added more flexibility by allowing users to model
different swale systems based upon land use. |
| Hydrodynamic Devices - This control practice is now available as a
source area control in addition to the drainage system control. |
| Minor corrections, changes and additional error checks. See the
WinSLAMMLog.txt file for details. |

of the changes in v 9.3.0,
see WinSLAMM
v 9.3 Summary.pdf
WinSLAMM - version: v 9.2.5 (release date 1 Sept 2007)
| Minor corrections and additional error checks. See the WinSLAMMLog.txt file for details. |
| Biofilter Modifications - Correct Land Use biofilter problem that incorrectly calculated Fraction of Runoff from Selected Source Areas value. Also changed the way biofilter elevation increments were calculated to remove problems that occurred due to elevation
interpolation. |
WinSLAMM - version: v 9.2.2 (release date 22 May 2007)
| Minor corrections and additional error checks. |
| Batch Data File Modifications - This feature, introduced in v 9.2.0, now also includes a site description text editor to allow you to change the site description text for a group of .dat
files |
| Outfall Treatment Train Order - The outfall treatment train has been modified to use the 'Other' control practice first, then wet detention ponds, followed by biofilters. |
WinSLAMM - version: v 9.2.1 (release date 19 March 2007)
| Minor corrections to the porous pavement cost estimation subroutine. |
WinSLAMM - v 9.2.0 (release date 4 March 2007)
| Streets - The program includes modified street
dirt accumulation and street cleaning functions to reflect newer street dirt
research. |
| High Efficiency Street Cleaners - Two types of street cleaners are now
available as part of the street cleaning control practice - Mechanical cleaners
and Vacuum or Regenerative Air cleaners. |
| Porous Pavement - We have added a routing and storage component to the
porous pavement control practice and added a porous pavement cross section
graphic to the data input form so that you can more easily visualize the various
elements of a porous pavement system. We have also added a porous pavement
infiltration degradation function and cleaning function to the program. |
| Rain File Analysis Tool - The program now includes a rain file
statistical analysis routine that will help you to analyze a long series of
rainfalls to determine which rainfall represents the typical annual rainfall
year. |
| Control Over the Detailed Output Options - We have developed a
description of the various detailed output option files that the model generates
as well as a way to turn these output options on or off. |
| Biofilter Performance Data - We have added a biofilter water balance
statistical summary as part of the event-by-event summary. This summary includes
the time the water surface is above the top layer of the biofilter and the time
that any water remains in the biofilter at all, information that some regulatory
agencies require when evaluating biofilters. |
| Stone Weeper Outlet - We have added a stone weeper outlet option for wet
detention ponds. |
| Model Version Updates - The model will now automatically update a
version 9.0 or later WinSLAMM data file (after the user enters standard update
information) to the current version of the model. Older WinSLAMM data files
(.DAT files) will, by default, receive a set of parameter files that come with
the distribution disk. If you do not want this to occur, you must re-set
the default values. To do so, in the Main Menu, go to Tools/Default
Model Options and press the 'File Update Options' button. In the .DAT File
Update Information window, enter the file names and other variables that you
want the program to update older version files to, by default. |
| Batch Data File Modifications - The program will now allow you to add or
change selected model parameters in any number of files at one time. This will
allow you to analyze a community's runoff volume or pollutant load much more
efficiently. |
| Rain Files - We have significantly expanded the
number and length of the rain files for the program. There are now over 140 rain
files, including many that cover over 40 years of rainfall events. The rain
files are available from the web site. |
| Miscellaneous minor upgrades, error checks, bug fixes, and interface
changes. |
If you purchased WinSLAMM in the past year and did not already receive
notification from us, you can get the latest version of
