摘要

Abstract

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.
