The post -doctoral research team of Hehai University has made breakthrough progress in the field of protection and restoration in the coastal belt

Recently, Dr. Zhao Yan, the High School of Hohai University, proposed the formation mechanism and the latest achievements of its landform effects after the edge wall erosion process, and formed a paper entitled "A Review on Bank Retreat: MeChanisms, Observations, and Modelling". Published on the top international journal "Reviews of Geophysics".

The evolution of the river mouth and coastal landforms after the erosion of the edge wall is essential. It is the forefront and hot issue in the field of coastal engineering. After the erosion of the edge wall, the backing process pose a huge threat to the safety of the coastal project, such as the lack of stability of the channel slope and the crash of the embankment. The results of this research are based on the research team of the post -doctoral research team of Zhao Yan. Through the cross -use of coast dynamics, sediment motion and earth mechanics, the reasons for the formation of different driving forces and environmental factors affect the backward erosion process. The common problems of the backing process under the wall erosion under different power systems; the mutual feedback mechanism of the evolution of the estuary and coastal landform evolution after the corrosion of the edge wall is proved to identify its differences at different time and space scale; summarize the backbone erosion after the edge wall erosion retreat Numerical models and prediction formulas, and discuss their applicability; in response to the problems existing in related research, point out the direction that needs to be broken in the art, such as the correction process of the edge wall of the multi -factor, which is the research and the evolution of the estuary and coastal landform evolution and research and research and the evolution of coastal landforms. Coastal belt protection and repair work provides technical support.

The study combined with many well -known scholars at the University of Auckland, New Zealand, the University of Southampton, the University of Padova, Italy, and East China Normal University in my country, and received the National Outstanding Youth Science Foundation Project "Coast Power Landmark: Multi -factor driving the tide beach system under the tide beach system Support of the Research Research ". The first author of the paper was Dr. Zhao Yan, and the author of the communications was Professor Gong Zheng.

It is understood that "Reviews of Geophysics" is sponsored by the U.S. Earth Physics Federation (AGU) and is the most influential international journal in the field of earth science. It ranks first among Earth and Planetary Sciences. The journal implements the PROPOSAL invitation system to comprehensively inspect the academic performance and international influence of applicants and its research team. About 20 documents are invited each year. This is the second academic paper completed by the author of the University of Hehai in the past 50 years. (Correspondent: Zhang Chunping, Hohai University)
