The Enhanced Stream
Water Quality Model (QUAL2E) is a steady state model for conventional
pollutants in branching streams and well mixed lakes.
|
QUAL2EU can be operated either
as a steady-state or dynamic model and is intended for use as a water quality
planning and regulartory tool. The model can be used to study impact of waste loads on instream
water quality and identify magnitude and quality characteristics of non-point
waste loads.
|
|
It can simulate up to 15 water quality constituents in any
combination desired by the user. The model is applicable to dendritic streams
that are well mixed. It uses a finite-difference solution of the
advective-dispersive mass transport and reaction equations. The model is
intended for use as a water quality planning tool.
The Enhanced Stream Water Quality Model with Uncertainty Analysis (QUAL2EU) is
an enhancement to the QUAL2E model that allows the user to perform uncertainty
analysis. Three uncertainty options are available.
Three uncertainty options are employed in QUAL2E-UNCAS:
sensitivity analysis, first order error analysis, and Monte Carlo simulation.
AQUAL2 is an interactive data
preprocessor program for the QUAL2E and QUAL2EU models. AQUAL2 can be used to
build input data files for either model. Q2PLOT is an interactive data post
processor program for both.

Detailed model description, input requirement
and output information, and system requirements
are available.
