Prediction of erosion evolution and deposition in the east coast of the Laizhou Bay after the implemention of the coastal planning |

Abstract: |
In this paper, the hydrodynamic model of Mike21 was used to simulate the flow current, deposition characteristics of the east coast of the Laizhou Bay, to predict its erosion and deposition evolution, Coupling the wave and current, to calculate the limit depth of scouring using empirical formula. By comparing the limit depth of scouring before and after planning reclamation, we found that the Longkou Bay would have a slight deposition. The wave and current of coastal water between the Jiehe River and Shihu area would become smaller and erosion intensity would become weaker, under the influence of engineering. All these analyses have shown that the coastal water between the Jiehe River and Shihu area would change from erosion to deposition when the planning reclamation is implemented. |
