Based on the whole-current equations of typhoon surge and its definite difference equations, this paper develops a numerical prediction mode! for typhoon surge along the southeast coast of China by taking into account of the typhoon model of circular storm. On considering the complexities of the coast and boundaries, the development of the model was made use of a relative ideal method to deal with the boundary conditions according to the characters of the model and the boundary position of the calculation grid. The calculations fairly coincided with the field observations, that proves this numerical prediction model satisfactory. 相似文献

Xiamen Bay in South China has experienced extensive coastal exploitation since the 1950s,resulting in some severe environmental problems.Local authorities now have completed or are implementing many environmental restoration projects.Evaluating the cumulative impact of exploitation and restoration activities on the environment is a complicated multi-disciplinary problem.However,hydrodynamic changes in the bay caused by such coastal projects can be characterized directly and definitively through numerical modeling.This paper assesses the cumulative effect of coastal projects on the hydrodynamic setting using a high-resolution numerical modeling method that makes use of tidal current speeds and the tidal prism as two hydrodynamic indices.Changes in tidal velocity and the characteristics of the tidal prism show that hydrodynamic conditions have declined from 1938 to 2007 in the full-tide area.The tidal current speed and tidal prism have decreased by 40% in the western part of the bay and 20% in the eastern part of the bay.Because of the linear relationship between tidal prism and area,the degraded hydrodynamic conditions are anticipated to be restored to 1972 levels following the completion of current and proposed restoration projects,i.e.33% and 15% decrease in the hydrodynamic conditions of 1938 for the western and eastern parts of the bay,respectively.The results indicate that hydrodynamic conditions can be restored to some extent with the implementation of a sustainable coastal development plan,although a full reversal of conditions is not possible.To fully assess the environmental changes in a region,more indices,e.g.,water quality and ecosystem parameters,should be considered in future evaluations. 相似文献

中国东南海岸台风暴潮数值预报模式 总被引：5，自引：3，他引：5
本文取文献[1]中描述风暴潮运动的全流方程组及其有限差分方程组,并取园形风暴的台风模型,作为我国东南海岸台风暴潮的一种数值预报模式.在注意到复杂海岸和海洋边界的同时,本文还针对本模式和计算格点的边界布局特点,取用了一种较理想的边界处理方法.在福建海岸,选取7705号强台风暴潮为研究实例;在广东海岸,选取8007号强台风暴潮和6508号强台风暴潮为研究实例,与实测情况相当吻合的验算结果,较好地证实了本数值预报模式. 相似文献
