This is the README file for animations in AVI format describing
withdrawal scenarios of the Sparta aquifer flow model documented
in WRIR 03-4132:

A PDF file format of the report is available on the compact disc (CD).

Development and Calibration of a Ground-Water Flow Model for the Sparta
Aquifer of Southeastern Arkansas and North-Central
Louisiana and Simulated Response to Withdrawals, 1998-2027.
By Paul McKee and Brian Clark

The animations contained on the CD were created using Tecplot
version 9.2-0-3 for MS-WINDOWS Copyright(c) 1988-2002 
Amtec Engineering, Inc.
Hydraulic-head data for the animations were read from the HDS
output file from MODFLOW-2000 and reformatted using code written
with the Microsoft Visual Basic 6.0 editor within Microsoft 
Access 2000 (9.0.2720) Copyright (c) 1992-1999.

Animations included on the CD consist of simulated hydraulic heads for:
sc1.avi  - scenario 1, baseline 1990-1997 withdrawals
           extended through 2027 and then to steady-state.
sc2.avi  - scenario 2, baseline 1990-1997 withdrawals
           extended through 2027, with reduction in industrial withdrawals
           in Pine Bluff and El Dorado.
sc3.avi  - scenario 3, 25 percent increase in baseline 1990-1997
           withdrawals over 30 years, with removal of selected industrial
           withdrawals in Pine Bluff and El Dorado.
sc1_oblq.avi  - Oblique view of scenario 1.
sc2_oblq.avi  - Oblique view of scenario 2.
sc3_oblq.avi  - Oblique view of scenario 3.


The CD should open automatically when inserted on most Windows machines.
To view manually load "OpenMe.html" on the CD into browser. Viewing of 
AVI files and HTML documents may vary widely depending on 
variables such as operating systems and user preferences. 
Preference settings in some browsers may cause a related 
mail client or previously loaded HTML document to become 
active instead of the enclosed OpenMe.html. This action 
requires the user to open a browser and specifically load 
OpenMe.html by either "FILE > OPEN" or "drag and drop". 
In other cases, when viewing animations, the AVI may be 
embedded in the browser. This requires user interaction with
a single mouse click on the image to invoke the animation. 
Other browsers may spawn applications such as Windows Media 
Player that will automatically play the animation.
