碩士 / 國立花蓮教育大學 / 鄉土文化研究所 / 95 / The shape of coastal geomorphology and landforms changes are influenced by the factors of natural and artificial. In natural factor, include with tide, wave, longshore currents, sand drift and landform of sea bottom. In artificial factor, include with a jetty harbor, detached breakwater, wave energy dissipating concrete block, even constructs check dam on the river, it’s also causes reduced of sand that deposits at the coastal. Recently research of erosion and deposits of coastal are concerning hydraulic engineering aspect of prototype modeling and simulation. In this study are integrate with GIS, and the data from long terms monition of River Management Office, drawing the digital terrain model（DTM） of sea bottom near the Hualien harbor, and to analysis the spatial relationship between the factor of sea bottom and coastal erosion and deposits, and which compared with hydraulic engineering modeling.
