Several functional forms for the eddy diffusivity in a lake or reservoir are analyzed for incorporation into a one-dimensional model for the vertical temperature structure of the water body. A suitable form for the neutral eddy diffusivity is found and this is used in solution of the heat transfer equation to simulate thermocline formation and seasonal development.
