  • TITLE: Decay of Pressure Fluctuation in the Hyporheic Zone around a Cylinder

    AUTHORS: Timothy Calappi, Carol Miller

    KEYWORDS: Hyporheic, Pressure, Cylinder, Scour

    JOURNAL NAME: World Journal of Mechanics, Vol.6 No.4, April 29, 2016

    ABSTRACT: Erosion around a submerged cylinder is a well-studied problem, and is of particular interest in bridge pier scour applications. Particles erode when lift and drag forces overcome a critical threshold. These forces are typically studied from above the water-riverbed interface and are related to geometry and surficial processes. The present study maps hyporheic pressure fluctuations as they are related to surface water velocity fluctuations. Relatively, high-pressure events in the subsurface promote a destabilizing force from within the riverbed and increase the potential for the mobilization of sediment. Differential pressure transducers were fitted within a vertical cylinder in a movable bed flume. The pressure ports were flush with the cylinder surface and below the water-sand interface. The three-orthogonal components of velocity were recorded synchronously with differential pressure measured over a 15 mm depth. As expected, results show decay in pressure fluctuations as a function of depth.
