On the bottom of the gulf, the normal gradients of T and S are zero. Nevertheless there is an additional bottom friction force depending on the velocity adjacent to the boundary. A coefficient of bottom friction, Cz, will increase in value when wave effects are presented. This value taken from Blumberg and Mellor [1] can be obtained from the following expression where j is the Von Kraman constant; H is the bottom topography; kb is the total number of sigma vertical level, and z0 is the bottom roughness parameter. In this paper, j is taken to be 0.4, while z0 = 0.01 m is used from Weatherly and Martin [2]. A radiation type of condition prescribes the normal currents across the open sea boundaries. As usual it is assumed that the motion in the sea is generated from an initial state of rest. Along the open boundaries the radiation conditions were applied
