VFDM 1.21

The Vegetated Filter Ditch Model (VFDM) was developed by Waterborne to design and evaluate the effectiveness of vegetated filter ditches as a Best Management Practice (BMP) to reduce the occurrence of agrochemical residues in downstream waterways. This model can also be used as a design tool to assist in the construction of a vegetated ditch for a farm system to help reduce the transport of agrochemicals into receiving waters.

VFDM was developed for the Yolo County, California, Resource Conservation District (RCD) under a grant by the California State Water Resources Control Board, Pesticide Reduction and Investigation of Source Mitigation (PRISM) Program.
