Hardware and Software Requirements
|
BASINS version 3.0 is a customized ArcView GIS application that
integrates environmental data, analysis tools, and modeling systems.
Therefore, BASINS hardware and software requirements are, at a minimum,
similar to those of other PC-based ArcView 3.x applications. BASINS
can be installed and operated on personal computers (PCs) equipped
with the software, random access memory (RAM), virtual memory, and
hard disk space presented in the table below. Because the performance
(response time) under the minimum requirements option might be too
slow for some users (especially when dealing with large data sets),
a preferred set of requirements is also included in the table below.
The hardware and software requirements
are as follows:
|
|
Hardware/Software
|
Minimum Requirements
|
Preferred Requirements
|
| Processor |
166-MHz Pentium |
400-MHz or higher Pentium |
| Available hard disk space |
For a single 8-digit watershed (cataloging unit), allow
for 300mb (50mb for BASINS system, 100mb for temporary file
processing space, and 150mb for BASINS Environmental Data)
|
For 1 State allow for approx. 2GB (50mb for
BASINS system, 1.2GB for temporary file processing space,
and 750mb for BASINS environmental data for approximately
1 state) |
| Random access memory (RAM) |
64MB of RAM + 128MB of permanent virtual memory
swap space |
128MB or more of RAM + 256MB of permanent virtual
memory swap space |
| Compact disc reader |
Quad speed reader (one-time use) |
24X or higher reader (one-time use) |
| Color monitor |
Configured for 16 colors (800x600) |
Configured for 256 colors (1024x768) |
| Operating system** |
Windows 95,98 Windows NT,ME,2000,XP* |
Windows 95,98 Windows NT,ME,2000,XP* |
| ArcView*** |
ArcView 3.1,3.2, or 3.3 |
ArcView 3.1, 3.2, or 3.3 with the Spatial Analyst
extension |
|
Hardware/Software
|
Minimum Requirements
|
Preferred Requirements
|
* The BASINS interface to QUAL2E does not work correctly under some
Windows OS.
** The BASINS online help files require Internet Explorer 5.0 or newer.
*** BASINS 2.x and 3.x are not compatible with the new ArcView 8.x

A note about the Spatial Analyst extension:
In BASINS 3.0, in order to run the SWAT model or the automatic watershed
delineator, ArcView requires the Spatial Analyst extension software.
This software is not included with ArcView and must be purchased
separately. The USEPA and ESRI have entered into an agreement whereby
nonprofit organizations (e.g. Federal, State, Tribal, or watershed
groups developing TMDLs) may obtain Spatial Analyst version 1.1
at a reduced price. For those who are interested please send name,
address, and phone number by email to kinerson.russell@epa.gov
to obtain a copy.
A Note on Software Conflicts on Windows 95/98:
Lotus Notes:
There is a well known conflict between Lotus Notes and ESRI's ArcView
3.x software. Please close Lotus Notes before running ArcView 3.x,
or BASINS 3.
Lotus Smart Suite:
It appears that ESRI's ArcView 2.x and 3.x software, and Lotus
Smart Suites both use the same file extensions "apr".
When Lotus Smart Suites is installed on the computer, Windows will
reassign all files with the extensions "apr" to Lotus.
The result is that ArcView projects files with the "apr"
extension may executeLotus Smart Suites which will then try to read
the file as a Lotus Approach file.
NHD ArcView Tool Kit Extensions:
If you have downloaded the National Hydrography Dataset (NHD) ArcView
toolkit extensions from the NHD/USGS web site at "http://nhd.usgs.gov",
please do not turn these extensions on while in a BASINS session.
When BASINS downloads NHD data it reformats the data into shape
files and "dbf" files. When the NHD toolkit extensions
are turned on, it will look for the NHD data in it's original ARC/INFO
format. When it can not find the correctly formatted data, it will
cause a series of cascading script errors in BASINS which will corrupt
your project.
