Abstract
With rapid development of economy, the crisis of land resources is faced. Land expansion by enclosing sea in estuaries has become an important carrier for city space extension. In this paper,the large-scale marine reclamation project in the Oujiang River Estuary (ORE) of Wenzhou shoal was taken as an example.Based on the intoduction of the study area,the 3D marine numerical model (EFDC) was setup and used for simulation of sediment enviroment and morphological changes induced by the reclamation. The results indicated that the project doesn’t have obvious adverse effects on its nearby sediment environment and seabed. On the contrary, it settles the problem of mouth bar of the ORE and provides some advantages to maintain and steady the deep water channel and improve the sail condition from the north mouth of Oujiang River to Huangda’ao channel.
