NAME
GenScn - GENeration and analysis of model simulation SCeNarios
ABSTRACT
Analyzing and managing the high volumes of input and output of
complex river basin models is a major task. These models are used
to simulate water quantity and quality for numerous scenarios of
changes in land use, land-use management practices, and water-
management operations. To assist with that process, an interactive
computer program, GENeration and analysis of model simulation
SCeNarios (GenScn), was developed to create simulation scenarios,
analyze results of the scenarios, and compare scenarios.
METHOD
GenScn provides an interactive framework for analysis built around
an established and adaptable watershed model. The graphical user
interface (GUI) uses standard Windows 9x/NT components. The
Hydrological Simulation Program--Fortran (HSPF) is used for
simulating the hydrologic and associated water quality processes on
pervious and impervious land surfaces and in streams and well-mixed
impoundments. MapObjects LT from Environmental Systems Research
Institute, Inc. (ESRI) is used to provide mapping functionality.

HISTORY
Version 1.0 1998/08/14 - Initial release.
DATA REQUIREMENTS
Meteorologic records of precipitation and estimates of potential
evapotranspiration in a Watershed Data Management (WDM) file are
required for watershed simulation. Air temperature, dew point
temperature, wind, and solar radiation also are required for
snowmelt. Air temperature, wind, solar radiation, humidity, cloud
cover, tillage practices, point sources, and (or) pesticide
applications may be required for water-quality simulation. Physical
measurements and related parameters are required to describe the
land area, channels, and reservoirs. If mapping is to be available,
Geographical Information System (GIS) data in the form of ESRI shape
files must be included.
OUTPUT OPTIONS
Output options include graphical and tabular display of both
observed and simulated data. Output may be viewed interactively or
written to files.
SYSTEM REQUIREMENTS
For installation of GenScn, 60 megabytes of free disk space is
needed.
To run GenScn, the following are necessary:
- Windows 9x or Windows NT 4.0 or higher
- 486 or greater processor, running at 50 megahertz or faster
- 16 megabytes of memory
- 60 megabytes of free disk space
- display resolution of 1024x768
For optimal performance, the following are recommended:
- Pentium processor, running at 200 megahertz or faster
- 64 megabytes of memory
- 100 megabytes of free disk space
- display resolution of 1280x1024
- color printer
