Non point source pollution

Abstract

Non Point Source (NPS) pollution, a major contributor to the degradation of water quality is caused by water movement over and through the surface of the land. Location of NPS pollution runoff, types of areas drained, and drainage channels are data vital to leaders in agricultural, forestry, and urban planning industries. These data can be used by state and federal agencies for planning purposes and for prioritizing allocation of resources. A study has been conducted to identify areas of prime NPS pollution concern using remotely sensed imagery and GIS modeling techniques. A model has been designed to identify, quantify and prioritize areas of NPS contribution potential within a water quality basin area.
