Interpretive Summary: Sediment and large rocks often are transported in runoff during extreme events. The sediment can deposit in a runoff-measuring structure and give erroneous readings. The drop-box weir (DBW) is one of only a few flow-measuring devices capable of measuring sediment-laden flows. Recent studies have extended its utility from large watersheds to small plots and watersheds. Furthermore, recent hydraulic studies have guided adaptation of the Coshocton wheel, a proportional sampler, for use with the configuration of the DBW used on runoff plots. This article presents a short history of the development of the DBW and it use with the Coshocton wheel on runoff plots in a study of application of manure on frozen soil. It also lists other studies where the DBW has been used.
