The School of Geography, The University of Leeds, Leeds, LS2 9JT, UK. Tel: +, Fax +, E-mail: [email protected]. developments in geographic information systems (GIS) technology provide the tool to spatially generate, store, manipulate, and retrieve the disparate input data required for modeling, particularly distributed-parameter modeling. For example, the Agricultural Nonpoint Source Pollution (AGNPS) distributed-parameter model, a cell-based model.

    In contrast, in non-point source pollution or NPS, there exists multiple sources of pollution. The most noteworthy example of non-point source pollution is urban run off, where stormwater washed off of parking lots, roads, highways, and lawns enter a water body, contaminating it with pesticides and fungicides that are contained in the run off. Common Non-Point Source Pollutants; Learn about some of the most Common Non-Source Point Pollutants. Sediment These pollutants are tiny particles of rock and soil from soil erosion and construction sites that clog water systems, smother aquatic life, transport other contaminants, and stirs-up sediments in the water.

    Spatial Distribution of Non-point Source Pollution in Vembanad Lake Kichu Paul, Binoy Alias M. & Shiny Varghese An open source GIS, QGIS, is used to The objective of this study was to determine the spatial distribution of the various pollutants across the Vembanad Lake. The scope of the study covers the following. Non-Point Source Pollution. Non-point source pollution does not come from a specific source. Instead, it originates from many places, or from a widespread area. We all contribute to non-point source pollution when we improperly use or dispose of fertilizers, pesticides, oils, grease, pet or animal wastes, and trash.

recent applications of GIS to the modeling of non-point source pollutants in the vadose zone with deterministic solute transport models. The compatibility, strengths, and weak-nesses of coupling a GIS to deterministic one-dimensional transport models are discussed.

BACKGROUND IN NON-POINT SOURCE POLLUTANTS Non-point source pollutants (e.g. Introduction: Assessing Non‐Point Source Pollution in the Vadose Zone with Advanced Information Technologies Dennis L. Corwin USDA‐ARS, U.S. Salinity Laboratory, Riverside, CACited by:   Assessment of the environmental impact of Non Point Source (NPS) pollutants on a global, regional and localized scale is the key component for achieving sustainability of agriculture as well as preserving the environment.

The knowledge and information required to address the problem of assessing the impact of NPS pollutants like Nitrogen (N), Phosphorus Cited by: The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack” (Hill, ).

Factories and sewage treatment plants are. Further a GIS can be used to display modeling results in a manner that is understandable by the lay person. Results can be prepared in a wide array of graphical formats enabling one to better visualize model predictions.

Using GIS for Point Source Pollutant Modeling Anthropogenic pollution is a continuing issue throughout the world. Point source pollution consists of that which comes from a single, identifiable location.

This typically consists of effluent from industry into the Size: KB. vadose zone, any quantitative analysis of contaminant transport must first evaluate water fluxes into and through the vadose zone.

Water typically enters the vadose zone in the form of precipitation or irrigation (Figure ), or by means of industrial and municipal spills. Some of the rainfall or irrigation water. Introduction. Eutrophication caused by the enrichment of nitrogen and phosphorus is degrading surface water quality throughout the world (Beeton,Smith,Cherry et al.,He et al.,Ouyang et al., ).While a variety of measures have been effectively implemented to tack nutrient pollution from point sources, diffuse nutrient loading is of increasing concern in Cited by: The Geographic Information System (GIS) has been extensively integrated into hydrology and non-point source (H/NPS) pollution modeling.

However, few studies have been carried out on the effect of GIS inputs on NPS modeling and the prediction uncertainty related to the combination of different GIS by: The geospatial approach enables the collection, analysis and modeling of relevant data with an advantage of combining existing and acquired geospatial data onto a single IT platform, thus enhancing strategic decision making for int egrated catchment management.

KEY WORDS: Non point source (NPS) of pollution, contaminant load model, catchment. Non-Point Source Pollutant Modeling Analysis and Prediction David Munn. T/F: Because they are of smaller scale, non-point source pollution sources are more easily regulated and controlled than are point resources.

False T/F: The Cuyahoga River in Ohio has degraded dramatically over the past 30 years. Current: Major Types of Nonpoint Source Pollutants There are many major types of nonpoint source pollutants that can and are harming the quality of streams, rivers, and lakes across Indiana.

Assessing Watershed Nonpoint Source Pollution Using a Geographical Information System (GIS) Changhua Weng The non-point source (NPS) pollutants are contaminants of surface and subsurface soil and water resources (e.g., sediment, fertilizers, pesticides, salts, and trace elements) that are diffuse in nature and cannot be traced to a point location.The current applications of geographic information systems (GIS) applications to non-point-source pollution modeling for agricultural area are reviewed with respect to the requirements for GIS, the hydrological/water quality modeling processes, and integration between GIS and Non-Point-Source Pollution (NPSP) models.EPA/// June Modeling of Nonpoint Source Water Quality in Urban and Non-urban Areas by Anthony S.
