| 中文摘要: |
In studying sand beach erosion and protection tactics in Liaoning Province, the authors calculated the wave data of 27 a period (1963-1991) at Bayuquan Observation Station in Liaodong Gulf.Together with the beach levellings and some simple marking stakes monitoring end by having the aid of local annals, the paper analysed the present situations of the coastline and the causes of sand coastal recession and serious consequences, and then discussed the dynamic process of alongshore sand transport.Simultaneously, based on alongshore sand transport model, oneline cut-and-fill theory and dynamical water model (sea level rise), the authors preliminary estimated beach process for the future in the area.
Recently, the coastline is being eroded and 2/3 of the sand coast is subjected to erosion, which the recession rate of the individual sector exceed 7.0 m/a.Coastal erosion has threatened villages, roads, factories and tourist resources.Sea level rises and the decreasing amount of materials by rivers discharged into the sea and the activities of man, made coastline recession rate accelerate, and cause a great loss of land in the area. |
