AB: The AGNPS model is a microcomputer program capable of modeling the erosion
process and simulating the water erosion and transport of sediment, nutrients
and flow for watersheds ranging from 1 to 50 000 ha size. With proper
modifications of the universal soil loss equation factors, excellent
agreements between the simulated and measured sediment yields were obtained
for the Shihmen Reservoir watershed. The model input data were collected
initially by the technique of remote sensing and geographic informa tion
system, and processed with the ARC/INFO Geographic Information System
software. The predicted sedimentation depth for the watershed averages about
2.5 mm/yr, which is not significantly different from the observed rate, but
exceeds what is observed in the US. It is, therefore, necessary to prescribe
appropriate soil and water conservation practices to control the sedimentation
problem in reservoir watersheds in Taiwan. -Author

AB: Watershed data are being collected in Taiwan for testing the AGNPS model,
a micro-computer program to model the erosion process and simulate the water
erosion and transport of sediment, nutrients and flow for watersheds ranging
from 1 to 50 000 ha size. Excellent agreements between the simulated and
measured sediment yields were obtained for the Tsengwen Reservoir watershed.
The model input data are collected initially by the technique of remote
sensing and geographic information system. It was found to be necessary to
prescribe appropriate soil and water conservation practices to control the
reservoir sedimentation problem in Taiwan. The model is also capable of
identifying areas within the watershed with high erosion and sediment yield.

AB: This paper presents a computerized system developed by integrating GIS and
a dynamic, event-based, nonpoint source pollution model. The GIS software
used for the integration was pc-ARC/INFO (Environmental Systems Research
Institute, Redlands, CA). Using the pc-ARC/INFO Simple Macro Language (SML),
Pascal, and batch programming, a menu-driven system was developed that
integrates the Agricultural Nonpoint Source pollution model (AGNPS) with pc
ARC/INFO. Running on a DOS platform with 640 KB of memory, the integration
prototype converts a set of pc-ARC/INFO coverages into an AGNPS input data
file. -from Authors

AB: A tillage study was conducted for six years on a 3.8 ha watershed planted
to cotton in the Limestone Valley region of northern Alabama. The tillage
included three years of conventional (CvT), followed by three years of
conservation tillage (CsT). Curve numbers (CN) were determined by the SCS
method and a method developed assuming a log-normal probability distribution
of potential maximum retention, S. The published CN of the average soil
moisture condition or antecedent moisture condition II (AMC II) fo r the study
site are 78 and 75 for CvT and CsT, respectively, which are recommended in
many watershed/water quality computer simulation models such as CREAMS and
AGNPS. The results showed that CN of AMC II (CN-II) calculated by the
log-normal method were 83 and 88 for CvT and CsT, respectively. These were
slightly higher than those calculated by the SCS method which were 82 for CvT
and 86 for CsT. The calculated CN-II values were higher than the published
CN-II values but the order of magnitude was reversed . -from Authors

PY: 1993
AB: Geographic information systems (GISs) are computer-automated, data
management systems simplifying the input, organization, analysis, and mapping
of spatial information. Because nonpoint-pollution models simulate distributed
watershed basin processes, a heterogeneous and complex land surface must be
divided into computational elements such as grid cells. Model parameters can
be derived from each grid cell directly from maps using GIS. Cell size
selection, if arbitrarily determined though, yields ambiguou s if not
erroneous results. This paper investigates the effects of cell size selection
through a sensitivity analysis of input parmaeters for the Agricultural
Nonpoint Source Pollution Model (AGNPS). Model grid-cell sizes were found to
be the most important factor affecting sediment yield. As the grid-cell sizes
increase, stream meanders are short-circuited. The shortened stream lengths
cause sediment yield to increase by as much as 32%. -from Authors

AB: Watershed data are being collected in Taiwan for testing the AGNPS model.
The model input data are collected initially using remote sensing and a
geographic information system. The predicted soil loss for the Bajun River
basin corresponds closely with previous estimates based on major river and
reservoir sedimentation data. This is a clear indication that the AGNPS model
is capable of providing a quantitative evaluation of on-site/off-site damage,
rating basin response, and planning conservation strateg ies on the local,
regional and even national level. -from Authors

AB: The objective of this study is to integrate the effective and powerful
tools of Geographic Information System (GIS) and the Agricultural Nonpoint
Source Pollution Model (AGNPS) to quantify erosion problems in the Bajun
Watershed, Taiwan. The AGNPS model input data were obtained by remote sensing
and GIS techniques. The estimated annual soil loss from this watershed basin
is about 259 t/ha. It is, therefore, necessary to prescribe appropriate soil
and water conservation practices to control the volume of soil loss within
acceptable (or tolerable) limits. -from Author

AB: Models to predict the magnitude of agricultural nonpoint-source pollution
in streams have been developed to meet a growing demand for management
information. The Agricultural Nonpoint Source (AGNPS) model requires 20
parameters to calculate potential nonpoint-source pollution for a watershed.
Landsat thematic mapper data, SPOT multispectral data, and SPOT panchromatic
data were tested to determine their ability to provide selected inputs to
AGNPS. Each data set was classified using supervised and unsupe rvised
methods, and the accuracy of each classification was evaluated using
contingency tables and the kappa statistic. -from Authors

AB: Grid- and contour-based digital elevation models are readily available.
Terrain analysis methods use these data to estimate the topographic attributes
of a catchment, many of which are essential parameters in hydrologic and water
quality models. Integration of these techniques into hydrologic and water
quality models permits better representation of the effects of three
dimensional terrain on runoff and erosion processes and improves the
efficiency of topographic data input. Terrain analysis methods wer e
interfaced with the agricultural nonpoint source (AGNPS) pollution model to
demonstrate how this integration can be achieved. Two terrain-enhanced
versions of the AGNPs model were developed: AGNPS- C, a contour-based version,
and AGNPS-G, a grid-based version. These terrain-enhanced models automatically
generate the cell network, the cell connectivity, and the required topographic
parameters. Peak discharge predicted by the three versions of the AGNPS model
for five storms on a small catchment near Treyno r, Iowa, were similar, but
sediment yield predictions exhibited some differences. Sensitivity analysis
shows that flow path lengths and contributing areas computed by the terrain
analysis depend on cell size. -Authors

AB: Components of the watershed model, AGNPS (agricultural nonpoint-source
model) are hydrology, erosion, sediment transport, transport of nitrogen and
phosphorus, and chemical oxygen demand. Using a cellular structure, runoff,
sediment, and chemical variables from the watershed provide input to a lake
model. This one-dimensional model of water bodies simulates temperature
stratification, mixing by wind, sedimentation, inflow density current, and
algal growth. Unsteady advection-diffusion equations characte rize the
dynamics of suspended sediment, soluble and sediment-attached N and P, and
chlorophyll. This model, AGNPS-LAKE, is driven by random generation of weather
conditions on a daily basis. Resulting impacts of alternative management plans
are simulated by changing agricultural practices and land use, thereby
modifying inflow characteristics to a lake. -from Authors

AB: A geographic information system was used to assemble and retrieve the
physical parameters required to estimate sheet and rill erosion and water
quality effects of applying II resource management systems to 16 farms in
Idaho's Tom Beall watershed. A linear programming model was used to determine
the economically efficient (optimal) systems for reducing total erosion and
nonpoint-source pollution in the watershed. The water quality effects of the
optimal resource management systems were evaluated using th e Agricultural
Nonpoint Source (AGNPS) model. Minimum tillage with either cross-slope farming
or contour farming was the most economically efficient system for reducing
farm-level erosion rates. All but two farms had to switch from conventional to
minimum tillage to reduce the average erosion rate in the watershed to the
tolerance (T) level [11.2 t/ha/yr (5 tons/acre/year)]. -from Authors

Abstract: This report provides the results of a review of seven non-point
source (NPS) models to determine their applicability for New Brunswick based
on existing literature, requirements for and availability of data, and the
end use envisioned. The models were classified according to whether they
were intended mainly to address on-farm or off-farm concerns, and whether
they could serve best as research or planning tools. The models reviewed
include MUSLE (modified universal soil equation), GAMES (Guelph model for
evaluating effects of agricultural management systems on erosion and
sedimentation), AGNPS (agricultural non-point source pollution model), CREAMS
(chemicals, runoff, and erosion from agricultural management systems) and
GLEAMS (groundwater loading effects of agricultural management systems),
SWRRB (simulator for water resources in rural basins), and ANSWERS (areal
non-point source watershed environment response simulation).

Abstract: Agricultural Non-Point Source Pollution Model (AGNPS) is a widely-
used computer model to estimate sediment and nutrient yields from
agricultural catchments, and it has been used to evaluate impacts of
differing land management strategies on surface water quality. The project
has enhanced the capabilities of AGNPS to model the effects of three
dimensional terrain on erosion processes and to make it compatible with
digital elevation models (DEMs) and DEM data bases. Both grid-based and
contour-based versions of the terrain-enhanced AGNPS model were produced.
Both versions compute important topographic input parameters, such as slope,
upsloperunoff contributing area and plan curvature, for use in AGNPS. The
grid-based version uses digitized grid elevation data obtained from
topographic maps, and the contour-based version uses vector elevation data
obtained from such maps. The effects of grid size and contour interval on
computed values of the topographic parameters were determined and application
of the methods to prediction of sediment yields from several digitized
watersheds is illustrated in the report.

Abstract: Three projects and a program of technology transfer were conducted
under the Pennsylvania Fiscal Year 1988 State Water Resources Research
Grants Program (PL 98-242, Sect. 104). In a completed study focused on the
protection of water supplies, mature slow sand filters were found to remove
100 percent of Cryptosporidium and Giardia cysts. A site specific study
examined the behavior of sedimentary iron and manganese in an acid mine
drainage wetland system. A study was initiated to link a comprehensive
non-point source model, AGNPS with current GIS technology to enhance the
models' utility for evaluating regional water quality problems related to
non-point source agricultural pollution.
