Hydraulic Conditions Required To Not Move Unconsolidated Surface Material Located Within Feedlots, John E. Gilley, Gregory D. Boone, David B. Marx

Department of Biological Systems Engineering: Papers and Publications

Beef cattle feedlots contain unconsolidated surface material that accumulates within feedlot pens during a feeding cycle. Runoff from feedlot surfaces is diverted into settling basins. The storage capacity of the settling basins will be substantially reduced if large quantities of solid material are transported in runoff from the feedlot surfaces. The objective of this study was to identify the hydraulic conditions that will not move unconsolidated surface material located within feedlots in order to minimize sediment transport. Selected sizes and a composite sample of unconsolidated surface material were placed within 0.75 m wide by 4.0 m long metal frames. Flow …
