Modelling the steady-state circulation in a distorted physical model of the Windermere Basin Modelling the steady-state circulation in a distorted physical model of the Windermere Basin Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-101991enTwo depth-averaged circulation models were applied to a distorted physical model of the Windermere Basin of Hamilton Harbour. One of the models, which includes the nonlinear advective terms, was successful in reproducing the hydraulically induced steady-state circulation. Using a Lagrangian model and the above circulation, trajectories observed in the physical model were replicated. Model sensitivity to changes in the bottom friction and horizontal diffusion of momentum were studied. An increase in each was found to decrease the size of zones of recirculation. Key words: distorted physical model, circulation model, bottom friction, horizontal diffusion.http://creativecommons.org/licenses/by/4.0/Canadian Journal of Civil Engineering518756-764 Tsanis Giannis Τσανης Γιαννης Krestenitis, Yannis N M.
