2006 ASABE Annual International Meeting
Vegetative filter is one of the agricultural best management practices that helps reduce the deterioration of the surface waters. These filters use natural processes to remove a portion of the sediment and other pollutants carried by runoff before the water enters a water-body. The project aims at gathering elevation data in field-scale vegetative filters with the help of Geographic Positioning Systems (GPS) and analyzes the flow accumulation with the help of Geographic Information Systems (GIS). The overall vision and objectives for this project include (1) To determine the effectiveness of VFS by visual field observation and validation by flow mapping procedures in ArcGIS 9, (2) To compare the area ratios and percentage of flow along each stream segment at The authors are solely responsible for the content of this technical presentation.

This study is of great significance in regard to key water quality and surface runoff issues, which are gaining broad awareness while developing consciousness about effective management practices and good land stewardship values. This paper will present the data and results for this study, which is still on going.
