Abstract: A 3‐in. (7.62‐cm) Parshall flume is installed in a channel and flow rates are measured with lateral flume crest slopes of 0, 3.6, 6.5, 9.0, 13.3,

Abstract: A study was conducted to revise the procedure for adjusting discharge measurements in a cutthroat flume subjected to settlement in free-flowing conditions. A series of 57 tests was performed on six different size cutthroat ...

Abstract: This paper presents results from a comprehensive laboratory study of the effects of a fine grained sediment (clay) carrier fluid on the hydraulic gradient of sand-sized sediments (600–2,000 microns) in a 103-mm diameter ...

Abstract: Near‐prototype flume studies were conducted in which riprap‐protected embankments were subjected to overtopping flows. Embankment slopes of 1, 2, 8, 10, and 20% were covered with riprap layers with median stone sizes of ...

Abstract: A study was conducted to determine how fall distance, or drop height, beneath a culvert outlet affects the dimensions of localized scour. Eighteen experiments were performed in which flow discharged from a circular, ...

Abstract: Impoundments constructed to encapsulate waste materials must resist the natural erosive processes to prevent exposure and release of the waste. One erosive process that has been difficult to predict is gully intrusion. ...

Abstract: Erosion rates of unsaturated compacted Na‐montmorillonite clays are measured under a range of tractive stresses from surface flows in a rectangular flume. The degree of saturation of compacted samples ranges from 0.52–0.97. ...

Abstract: This study investigates headwall influence on local scour downstream of culvert outlets. Scour holes produced by discharging jets of varying duration and magnitude through circular culverts onto a horizontal sand bed were ...

Abstract: An investigation conducted to derive a design procedure for estimating the dimensions of scour in a variety of noncohesive materials at culvert outlets is presented. Scour hole dimensions of depth, width, length and volume ...
