Abstract：The equilibrium headland-bay plane curve shapemodle is built based on BP neural network. This paper generalizes the method of determining whether the shoreline reaches equilibrium states by using this model, and verifies the shape of Taquaras-Taquarin bay, which has achieved a good result. It is used to design man-made headland and compared with the parabola model. The result shows that BP neural network equilibrium headland-bay plane curve shape model in fits the cape better, and it is more easier to operate.
