Time-Lapse of Edge-of-Field Event Near Fort Wayne, IN

Time-lapse photo of a rainfall-induced runoff event at an edge-of-field surface site near Fort Wayne, Indiana, on May 10-11, 2016. Edge-of-field monitoring is used to assess the quantity and quality of agricultural runoff and evaluate the effectiveness of conservation practices that aim to reduce nutrient loss. The runoff from an agricultural field is channeled through the H-flume, where the flow is quantified and samples are taken for water-quality analysis. Runoff events can happen at any time of the day or year, but each event provides valuable information, so the ability to capture data using automated equipment and two-way communication is crucial.
