Filter strips are commonly used on agricultural land to reduce the runoff of sediment and nutrients into streams and ditches. Filter strips are often designed to have the same width all along the edge of the bank of the stream but water running off of agricultural fields is often concentrated, meaning that some areas of the filter strip will be overwhelmed while others will receive very little runoff. AgBufferBuilder uses digital elevation models to identify areas where runoff is likely to concentrate so that the filter strip can be designed accordingly. In other words, the filter strip will be wider along segments where more runoff flows and smaller where runoff is less. In this webinar recording, Dr. Mike Dosskey with the US Forest Service, introduces the AgBufferTool and shares results of modeling trials to compare the environmental performance of different filter strip designs.
