Abstract: A level 2½ turbulence closure model is used to investigate the dependence on water depth H of bottom stress τb and quadratic drag coefficient Cd for a steady barotropic pressure-driven current in unstratified water when ...

Abstract: Frequently the mixing length l in second-order closure models is assumed to have a constant value l0 = ?L at large distances from the bottom with a magnitude proportional to the first moment L of turbulent intensity. ...
