Technical Abstract: A new approach for discretization and analysis of agricultural watersheds, called riparian catchments, has been included in the Agricultural Conservation Planning Framework, Version 3, a watershed planning toolbox used with geographic information systems software, available at www.acpf4watersheds.org. Riparian catchments are developed by dividing the stream network into a set of segments of a length selected by the user. Watershed contributing areas are delineated to each segment and then divided by the stream. The resulting riparian catchments each delineate the land area that can contribute overland flows to a defined length of streambank found on either side of each stream segment. Results can facilitate analyses for evaluating riparian zone management opportunities from a whole watershed perspective. Attributes of the riparian catchment, including size, topography and soil characteristics can be used to map functional buffer designs and the potential for siting practices such as saturated buffers for tile drainage treatment. A variety of additional analyses are possible, the poster will present several examples from a case-study watershed.
