Abstract: This paper presents a global model describing the jet plane flow due to a tidal or river discharge. This model characterizes the geometry and the velocity field of the ebb-tidal jet in the whole domain including the effects of friction and bottom slope. The model does not have adjusting coefficients since they are obtained during the integration process. It can be concluded that higher values of the friction coefficient increase the jet width, whereas higher bottom slope reduces the jet width due to the incoming complementary water. Moreover, for small slopes, the area affected by the flow varies, essentially, with the friction coefficient, whereas for higher sloping bottoms this area can be assumed constant.
