Effects of bottom slip and variable eddy viscosity in hydrodynamic models of Lake St. Clair / by T.J. Simons and W.M. Schertzer.: En13-5/86-209E-PDF
"Two modifications of the conventional steady-state Ekman model with constant eddy viscosity and zero bottom velocity are considered. In the first case the constant eddy viscosity is retained but the no-slip bottom condition is replaced by a quadratic relationship between bottom stress and bottom current. In the second case the constant eddy viscosity is replaced by an arbitrary vertical profile of eddy viscosity and high-resolution finite-difference methods are employed to solve the vertical Ekman problem. Both methods are applied to Lake St. Clair and the results are compared with current measurements made during 1985 and with results from the basic model with constant eddy viscosity and zero bottom slip. It is shown that the modified models remedy the major shortcoming of the basic model which underestimates current speeds near the bottom"--Abstract.
