【 摘 要 】

At Yunlin county a major development of over 10,000 ha of reclamation is being planned for port related industries. The development is taking place along a coast that bordered by Choshui river and the Wai-San-Ting sandbar. Detailed modeling using MIKE21 package with wave, flow and sediment transport modules were used to assess the morphological changes. Four such "relict" deltas were identified according to its ancient river courses. The decay of the sandbars was mostly independent due to the major discontinuities at sandbar headlands and tidal channels. The analysis of the complex morphological processes has provided an important insight into the probable impacts of coastal developments and guided the expensive and time-consuming model operations.
