Vegetative filter strips (VFS) are the most widely implemented mitigation measures to reduce the transfer of pesticides to surface water via runoff and erosion. VFSMOD calculates the retention of water and sediment dynamically for each event based on actual environmental conditions. It provides the option to choose between different empirical and mechanistic pesticide trapping equations. On the other hand, the European FOCUS Landscape & Mitigation framework relies on fixed percentages for the reduction of water, sediment and pesticide for two different filter strip widths (10 m or 20 m).  The poster highlights the advantage of VFSMOD in more realistically addressing the actual performance of a VFS based on environmental conditions (e.g. antecedent soil moisture or rainfall intensity) and compound properties (sorption) as opposed to fixed default assumptions.
