Vertical Structure of Current in Homogeneous and Stratified Waters

  • N. S. Heaps
Part of the International Centre for Mechanical Sciences book series (CISM, volume 286)


In this section the hydrodynamic equations are formulated, mainly in order to state basic principles and introduce a notation. Simple solutions are then developed for water movements in a narrow rectangular basin subjected to steady wind directed along its length. Vertical structures of current are derived for both one- and two-layered systems representing, respectively, a lake during conditions of winter homogeneity and summer stratification. In spite of their simplicity, for the most part achieved by linearization, the use of constant coefficients of eddy viscosity and the neglect of the Coriolis force, the solutions illustrate some important facts about the dynamics of wind-driven flows in a long narrow lake. Perhaps the main interest of the analysis lies in the actual construction of closed solutions, satisfying appropriate boundary conditions, for lake circulation.
