【摘要】 介绍了第三代近岸海浪数值模式SWAN,并使用SWAN对辽东湾海浪进行了模拟。辽东湾平缓的淤泥质海岸为研究海浪底摩擦耗散提供了理想的条件。与实测数据对比分析表明,SWAN模式能够较好的模拟辽东湾近岸水域海浪。在8月南风过程中,底摩擦耗散起作用的范围主要集中于辽东湾北部10m等深线以浅水深变化平缓的地区。耗散强度随水深变浅而逐渐增强。更多还原

【Abstract】 The muddy seafloor with its gentle slope in the Liaodong Bay is an ideal location for studying the bottom friction dissipation to sea waves.The 3nd generation of wave model SWAN are introduced to simu-late waves of the Liaodong Bay.It is learnt from the comparison between the model results and the obser-vation data that the SWAN model works well to simuate waves in the coastal waters of the bay.It is shown in a numerical experiment for a south wind blowing process that the bottom friction dissipation give its effects on waves mainly in a gently slopy area with its water depth shallower than 10min the north of the Liaodong Bay,and the dissipation intensity becomes stronger with the water depth shallowing.更多还原
