Hydrodynamic influence of proposed excavated-in harbor in the Hengsha Shoal of the Yangtze Estuary Ⅰ: Numerical Model and Validations

Abstract

Abstract: Based on an unstructured-grid FVCOM model, a high-resolution hydrodynamic model of the Changjiang Estuary has been established. Through the extensive validation against the various observation data, including the current and salinity, this model could correctly reveal the hydrodynamic structures and their variations. It has provided a basic tool for assessing the impacts of the proposed excavated-in harbor of the Hengsha Shoal on the current field on local and adjacent regions.

Key words: Hengsha Shoal, excavated-in harbor, FVCOM

CLC Number:
