Creator:: Edwards, Kathleen A., MacCready, Parker, Moum, James N., Pawla, Geno, Klymak, Jody M., and Perlin, Alexander
Abstract:: Barotropic tidal currents flowing over rough topography may be slowed by two bottom boundary–related processes: tangential stress of the bottom boundary layer, which is generally well represented by a quadratic drag law, and normal stress from bottom pressure, known as form drag. Form drag is rarely estimated from oceanic observations...

Creator:: McCabe, Ryan M., Hickey, Barbara M., Dever, Edward P., and MacCready, Parker
Abstract:: Moored observations are used to investigate the seasonal change in vertical structure of the cross-shelf circulation at a midshelf location in the northern California Current System. A streamwise–normal coordinate system is employed to eliminate meander- and eddy-induced biases in the cross-shelf flow that are unaccounted for with an alternative, commonly...

Creator:: Warner, Sally J. and MacCready, Parker
Abstract:: Topographically generated eddies and internal waves have traditionally been studied separately even though bathymetry that creates both phenomena is abundant in coastal regions. Here a numerical model is used to understand the dynamics of eddy and wave generation as tidal currents flow past Three Tree Point, a 1 km long,...

Creator:: Warner, Sally J., MacCready, Parker, Moum, James N., and Nash, Jonathan D.
Abstract:: As currents flow over rough topography, the pressure difference between the up-and downstream sides results in form drag-a force that opposes the flow. Measuring form drag is valuable because it can be used to estimate the loss of energy from currents as they interact with topography. An array of bottom...
