AgBufferBuilder is a GIS-based computer program for precision design of vegetative filter strips around agricultural fields. The tool analyses the terrain for spatial patterns of overland runoff and designs a variable-width configuration that matches those patterns to provide a constant, user-selected, level of performance along the field margin. The tool also can assess the performance level of existing or hypothetical configurations.

Why Use AgBufferBuilder?

AgBufferBuilder 2.0 works with ArcGIS 10.0, 10.1, 10.3, and 10.4.

Development History

AgBufferBuilder utilizes relationships between buffer-area-ratio and performance that were developed using the process-based Vegetative Filter Strip Modeling System. Those relationships were, then, adapted to run with ArcGIS (ESRI, Redlands, CA). Key stages in the development of AgBufferBuilder are described in the following publications.
