In spring 2012, experimental agricultural plots in Goodwater Creek Research Watershed near Centralia, Missouri are being instrumented with Parshall flumes to measure runoff. These videos show ARS employees producing some of the experimental equipment needed to make the measurements.
The project: “Improving Water Quality in Agricultural Watersheds Underlain by Claypan and Restrictive Layer Soils” focuses on assessing water quality from plot to watershed scales, assessing soil quality at plot and field scales, and developing tools and techniques to quantify the impact of conservation practices in a watershed. Flumes attached to the concrete troughs featured in these videos will be used to measure runoff and pesticide, nutrient, and sediment transport from 1-acre plots under corn-soybean, switchgrass and willow tree production under different tillage practices and with and without conservation buffers. Knowledge about off-site transport of nutrients, pesticides, and sediment is critical to achieving economically sustainable crop production, which is increasingly important to both regional economies and the broader challenge of feeding the world.

CSWQRU Scientist Earl Vories presented a seminar entitled "Growing Rice Using Center Pivot Irrigation" as part of the "Innovations in Irrigation Education Conference" sponsored by the Irrigation Association in San Diego, California November 6-8, 2011.

CSWQRU conducted a rainfall simulation study during Summer 2011 at the University of Missouri’s Bradford Farm.* The study examined the effect of three tillage treatments (harrow, minimum-till and no-till) on transport of the herbicide atrazine and soil erosion.
