Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume Non-point source (NPS) pollution in the vadose zone (simply defined as the layer of soil extending from the soil surface to the groundwater table) is a global environmental problem.

Applications of GIS to the Modeling of NonPoint Source in the Vadose Zone: A Conference Overview D. L. Corwin* and R. J. Wagenet ABSTRACT Because of their ubiquitous nature and potential chronic health effects, nonpoint source (NPS) pollutants have become a focal point of attention by the general public, particularly regarding pollution ofCited by: 2.

GIS-based Modeling of Nonpoint Source Pollutants in the Vadose Zone Article (PDF Available) in Journal of Soil and Water Conservation 53(1) . 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. This chapter details efforts with nonpoint source pollution modeling and GIS in the United by: 3. 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.
