DISTRIBUTION DISKETTES

     NOTE:  k=1,024; m=1,048,576; b=1 byte

Included are 2, 3.5 inch (1.44mb, DS/HD) DOS (Disk Operating
System) formatted diskettes containing the Dilution Models for
Effluent Discharges model system (PLUMES, Version 3.00), dated
December, 1994.

This model system is designed for the IBM PC family of
microcomputer or compatible systems running under version 3.30 or
higher of the Microsoft or PC Disk Operating Systems (PC or MS
DOS--refer to DEVELOPMENT SYSTEM section).  Properly configured,
this model system and its support files and programs can be
executed under PC DOS or MS DOS 3.30 and later versions, DOS
4.0x, DOS 5.0x, or DOS 6.x.

To install the PLUMES model system and/or related support files
and programs on a hard disk, insert the first distribution
diskette in a compatible diskette drive.  Type

                    A:\INSTALL or B:\INSTALL

at the DOS system prompt and press the <Enter> key.  Then follow
instructions and respond to the prompts presented on the monitor
screen by the interactive installation program.  This is a
compressed, self-extracting, interactive installation program
with on-line, context sensitive help that contains the Dilution
Models for Effluent Discharges model system (PLUMES, Version
3.00), dated December, 1994.

     NOTE:  If the PLUMES model system is being installed
     from the PLUMES installation file (INSTALPL.EXE)
     downloaded from the CEAM electronic bulletin board
     system (BBS) or the Internet, then the user should type

                            INSTALPL

     at the DOS system prompt and press the <Enter> key. 
     This command assumes that the current default drive and
     sub-directory is the same drive and sub-directory that
     contain the file INSTALPL.EXE.  For further information
     on the CEAM BBS and access to CEAM software products
     through the Internet, refer to the TECHNICAL HELP
     CONTACT section.

     NOTE:  The content of the distribution diskettes can be
     copied to another set of "backup" diskettes using the
     DOS DISKCOPY command.  Refer to the DOS Reference
     Manual for command application and use.  The "backup"
     diskettes must be the same size and storage density as
     the original source diskettes.

The following FILE NAME AND CONTENT section provides a brief
functional description of each file by name or file name
extension type.  Other sections in this document contain
information about

     o recommended hardware and software configuration for the 
       execution of the model system and all support programs
     o program execution
     o minimum file configuration
     o program modification
     o technical support



_________________________________________________________________

FILE NAME AND CONTENT

The self-extracting, interactive, installation executable program
file exists in a compressed format to save disk space and file
transfer time.  This section contains a description of each file
that can be decompressed from the compressed distribution
diskettes and/or file.

Follow the instructions shown on the interactive installation
program screens and menus to install, decompress (extract), and
restore file(s) to their original name and size in order to place
the PLUMES model system in a usable format on a hard or virtual
disk.  For comparison purposes, the original date and time of
creation are also restored with each file.

     NOTE:  Execution of the INSTALL or INSTALPL command can
     extract one or more PLUMES model system files.  These
     files are automatically stored into DOS sub-directories
     on the hard disk.  The sub-directory structure, under
     which the sub-directories shown below are stored, is
     selected by the user during execution of the INSTALL or
     INSTALPL program.  The string "InstallationDirectory"
     will be used to denote the highest level default
     installation directory structure chosen by the user
     during execution of INSTALL or INSTALPL.  Below the
     installation directory, all files are grouped and
     listed by the appropriate DOS sub-directory name into
     which they will be automatically stored.

ROUTINE EXECUTION

     NOTE:  The symbol "<Enter>" represents pressing the
     <Enter> or carriage return key.  Responses and key
     strokes that can be typed by the user are underlined
     with the hyphen character (-) and/or enclosed by the
     angle bracket characters (<>).

     NOTE:  It is possible that the PLUMES model system
     could be incompatible with MS DOS and Windows software
     cache files SMARTDRV.SYS or SMARTDRV.EXE loaded from
     the system configuration files \CONFIG.SYS and/or
     \AUTOEXEC.BAT on the boot drive.  If any portion of the
     PLUMES model system prematurely halts, produces unusual
     results, and/or causes the host system to halt or hang,
     remove any SMARTDRV statements on the boot drive
     \CONFIG.SYS and/or \AUTOEXEC.BAT files, then re-boot
     the system to implement these changes before attempting
     to reuse any portion the PLUMES model system.

Introduction
~~~~~~~~~~~~
Complete the installation process to make the full or any portion
of the PLUMES model system and related files resident on a hard
(usually designated as "C:") or virtual disk drive.  Then modify
the \CONFIG.SYS system environment file and restart the
microcomputer system.  This needs to be completed only once for a
given installation of the PLUMES model system.

DOS Storage Path
~~~~~~~~~~~~~~~~
Verify that the PLUMES model executable task image files (*.EXE), 
other run time support files (e.g., EQNS), and user defined input
data file(s) are in the current default DOS sub-directory.  It is
convenient but not required to have these files in the same
sub-directory.

     NOTE:  To execute any executable task image file
     (*.EXE) for the PLUMES model system from any
     sub-directory located on a hard or virtual disk drive,
     add the PLUMES installation sub-directory (e.g.,
     C:\PLUMES) to the DOS search PATH and copy the file
     EQNS and other appropriate run time support files to
     the current default sub-directory.  One way to
     accomplish this is to add or modify the PATH statement
     in the system start-up file, AUTOEXEC.BAT (located in
     the root directory on the start-up or boot drive).  For
     example

     PATH C:\;C:\DOS;C:\UTIL;C:\WP51;C:\PLUMES

     If any portion of the PLUMES model system prematurely
     halts, produces unusual results, and/or causes the host
     system to halt or hang after pressing the help (<F1>)
     key, copy the file EQNS from the PLUMES model system
     installation sub-directory to the current default sub-
     directory from where the PLUMES model is being executed
     via the DOS search PATH statement.

     Refer to the DOS Reference Manual for PATH command and
     AUTOEXEC.BAT file application and use.

Routine Execution Steps
~~~~~~~~~~~~~~~~~~~~~~~
Step Description/Action
~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1)   Set the default drive to the disk containing the PLUMES
     model system sub-directory.  For example:

     A:\> C:<Enter>
          --

2)   Change the DOS default sub-directory to the sub-directory
     designated by the user during the installation program as
     the installation sub-directory (e.g., PLUMES).  Use the DOS
     CD (change directory) command at the DOS system prompt:

     C:\> CD \PLUMES<Enter>
          ----------

     NOTE:  A common problem is for a DOS executable file
     (*.EXE) to be unable to locate a file because it
     assumes the file is on the default drive and/or sub-
     directory when it is not.  If input and/or other run
     time support file(s) are not on the default drive and
     sub-directory, the user can type a drive and/or path
     name ahead of the file name.  For further information
     refer to the "File Name and Path Specifications" sub-
     section later in this document or the DOS Reference
     Manual.

3)   To execute the PLUMES model, type:

     C:\PLUMES> PLUMES<Enter>
                ------

     After an opening banner/registration screen is displayed on
     the monitor, press the <Enter> key to clear the screen and
     continue model execution.  The model will begin prompting
     the user for information needed for this run of the model. 
     The user should respond to any information screens, menus,
     and/or prompts displayed on the monitor screen.

4)   To execute the PLUMEHYD model, type:

     C:\PLUMES> PLUMEHYD<Enter>
                --------

     The user should respond to prompts displayed on the monitor
     screen.

5)   To execute the ULINE model, type:

     C:\PLUMES> ULINE<Enter>
                -----

     The user should respond to prompts displayed on the monitor
     screen.

6)   To execute the UPLUME model, type:

     C:\PLUMES> UPLUME<Enter>
                ------

     The user should respond to prompts displayed on the monitor
     screen.

Viewing Output Results
~~~~~~~~~~~~~~~~~~~~~~
After executing a PLUMES model system executable task image file
(*.EXE), the user can view an output file, if any, produced by
the execution of a model if and only if that file is in ASCII
text (non-binary) format.  Results can be viewed by scrolling
through the output file that was (1) a result of model or program
execution and/or (2) named by the user at a run time prompt.  A
word processor or text editor is convenient for this purpose, or
the command

                    TYPE filename.ext | MORE

can be used where "filename.ext" is the name of the output file. 
However, the TYPE command is awkward for output files that
exceeds the 80-column screen width.

Alternatively, the output file can be printed.  A compressed
print mode (132 column) should be used to avoid awkward--wrapped
around--output from lines that exceed 80 columns.  The DOS MODE
command can be used for this purpose.  For a parallel printer
assigned to LPT1, the DOS command

                         MODE LPT1: 132

will cause most printers to print in compressed mode.  For
further information, refer to the DOS Reference Manual.

File Name and Path Specifications
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A file name, path specification, and/or the parameter file name
argument "filename.ext" must be a unique and valid DOS path
and/or file name.  The user response "filename.ext" must also be
a valid PLUMES model system input or output file name -- either
furnished with the distribution package (refer to FILE NAME AND
CONTENT section) or created, designated, and named by the user. 
A file name used as input data for any program and/or model in
the PLUMES model system will be processed and executed in that
run of the program or model.

File names used for the input data and/or output listing files
(except for the test input and example output cases provided) are
arbitrary, but must follow the rules for DOS file names.  A file
name should assist the user with identifying the contents or
purpose of a file (e.g., INPUT.DAT, OUTPUT.LST).

Any file name can be from 1 to 8 characters and can have an
optional 1 to 3 character file name extension.  Any characters
beyond 8 in the file name or beyond 3 in the file name extension
will be truncated and ignored by the DOS operating system.  Refer
to the DOS Reference Manual for further information on file names
and disk file input/output procedures, rules, and commands.
