未来海平面上升对厦门海滩侵蚀的测算

Calculation of beach erosion caused by futural Sea level rise in Xiamen

本文通过波浪计算和理论海滩剖面方程的拟合，以Bruun模式为基础，根据Everts剖面积分方法，测算了厦门厦门大学海滨浴场、鼓浪屿港仔后海滨浴场沙滩未来100a海平面上升引起的海滩后退量值。与此同时，计算了Bruun模式的结果。计算结果表明，两处海滨浴场沙滩的后退值分别为14．81和13．95m，与Bruun模式的结果相当接近。

By counting wave conditions and fitting with theoretic beach profile equation, and byjoining Everts Integral Method with Bruun Model, beach recede value, caused by sea levelrise, in the future 100a in bathing beaches along Xiamen University and Gangzihou on Gulangyu Island have been calculated. At the same time, by applying Bruun Model individually, recede values are achleved. The calculated results on the study beaches are 14. 81 and13. 95m respectively, which are very close to the values by Bruun Model individually.
