Abstract

Hydrodynamics
of the Bosphorus Strait is examined with a three-dimensional ocean
model under the idealized conditions, while solving the full set of
the primitive equations for the simplified hydrography and geometry
of the strait. The response of the idealized model switching from
one steady-state to another, from a less frictional case to a more
frictional one or vice versa are investigated. The results show that
the model is successful in switching from a less frictional state to
a more frictional one, but has difficulties in the opposite
direction. Inconsistency between the reservoir stratification partly
defined by the initial condition and the maximal-exchange
characteristic of the steady-state solution of the restarted
simulation prevents a successful switch from a well-mixed case to a
reduced mixing solution.

Hydrodynamic Model Analysis of an Idealized Bosphorus Case with respect to Switching Steady-State Solutions

Abstract

Hydrodynamics of the Bosphorus Strait is examined with a three-dimensional ocean model under the idealized conditions, while solving the full set of the primitive equations for the simplified hydrography and geometry of the strait. The response of the idealized model switching from one steady-state to another, from a less frictional case to a more frictional one or vice versa are investigated. The results show that the model is successful in switching from a less frictional state to a more frictional one, but has difficulties in the opposite direction. Inconsistency between the reservoir stratification partly defined by the initial condition and the maximal-exchange characteristic of the steady-state solution of the restarted simulation prevents a successful switch from a wellmixed case to a reduced mixing solution.
