3.5 - Updated 3/21/2015 Version
3.5 supports Microsoft Excel 2013, Windows 10, and contains other minor
repairs and enhancements. See Version Notes and Installation
Instructions. This version has
been prepared without agency or user support.
The P8
User Forum can be used to post questions and share experiences. https://groups.google.com/forum/#!forum/p8-model Please send an email if you download the program
so that we can maintain a list of users. Please report problems
or suggestions and post them at the P8 User Forum. We
would like to begin collecting hourly precipitation and daily air temperature
files from various regions to support other user applications and development
of algorithms to generate hourly precipitation files based upon daily
records. The algorithms will
facilitate applications, since hourly records are not readily available in
many regions. If you want to
contribute, please post your datasets at the P8 User Forum. The latest
version supports input files from all previous versions. If your input
files are stored in the default program folder for a previous version, they
can be copied into the program folder for the current version
(C:\p8_UserFiles). This can be done after installation. Version 1 (1990) documentation provides detailed descriptions of algorithms and calibrations. Updates are described in the web documentation for the current version. The current version basically translates the DOS version with more bells/whistles and revised input/output formats. Most of the underlying algorithms and calibrations (now 20-25 years old) have not been changed. As far as I know, mass is still conserved and suspended particles still settle at about the same rate as they did in the 1980's, so the underlying concepts and calibrations are still valid. With the exception of street-sweeping efficiency factors, the default particle calibrations (NURP50, NURP90) based on information available as of 1990 have not been modified, users can create their own particle calibrations based on more recent and/or site-specific data. If the default calibrations are used, the user (not P8) assumes that they are valid. http://www.wwwalker.net/p8/v35/webhelp/splash.htm 12/19/2015 |
