Model of the water exchange through the Bosphorus (a hydrodynamic estimate of blocking conditions for the Bosphorus undercurrent

  • Analysis of Observations and Methods of Calculating Oceanic Hydrophysical Fields
  • Published:
Soviet journal of physical oceanography


A three-dimensional linear model of the stationary water circulation in the Bosphorus due to the river's outflow, density differences at the ends of the straits, and win is considered allowing for the earth's rotation and the bottom topography. The channel approximation and the method of the separation of variables are used to obtain the analytical solution of the problem. The solution obtained describes the main circulation elements which are know from observations. The influence of different parameters on the formation of vertical and horizontal structures of the velocity field is analysed.

Blocking conditions for the Bosphorus undercurrent are estimated. Possible variations in the structure of flows in the straits related to the regulated outflow of the rivers of the Black Sea basin are discussed.
