Abstract: AbstractOn a spillway chute, the upstream section is nonaerated, and a strong air–water mix develops downstream of the onset region of free-surface aeration. During a series of flood events, between 1997 and 2024, qualitative ...

Abstract: AbstractAt weirs and dams, a main component is the spillway system, for which the crest design dictates its performance. Among the weir crest designs, the circular weir presents the simplest geometry and remains commonly ...

Abstract: Hydraulic jumps are characterized by strong flow turbulence, flow aeration, and three-dimensional flow motions. Whereas comprehensive research into hydraulic jumps on smooth bed has improved the understanding of flow ...

Abstract: The effects of step edge and cavity shapes on skimming flow properties were investigated in a large-size 45° stepped chute model configured with uniform triangular steps, partially blocked cavities, and chamfers. The focus ...

Abstract: A hydraulic jump is a stationary transition from an upstream supercritical to a downstream subcritical flow. Hydraulic jumps with relatively low Froude numbers may be observed downstream of low-head hydraulic structures ...

Abstract: The entrainment, breakup, and interplay of air bubbles were observed in a vertical, two-dimensional supported jet at low impact velocities. Ultra-high-speed movies were analyzed both qualitatively and quantitatively. The ...

Abstract: Standard box-culvert designs are similar to ancient designs. The acknowledgment of the ecological impact of culverts and road crossings on rivers has led to changes in culvert design guidelines. A small triangular corner ...

Abstract: he use of Global Navigation Satellite System (GNSS)-tracked Lagrangian drifters allows more realistic quantification of fluid motion and dispersion coefficients than Eulerian techniques because such drifters are analogs ...
