감조하천의 유로단면변화에 따른 유황해석 = An Analysis of Flow Situation by Change Cross section of the Water-course in Tidal River

다국어 초록 (Multilingual Abstract)

The subject of this study apply to KyungSangNamDo Sachun-Si Sachun-bay sea area for builds up a industrial complex, and inquire into the phenomenon in compared after with before reclamation. I investigated, how to remove these harmful influence and make a estimate that a water-level, flow direction and river-bed evolution by inflow of river, wave' s attack. So we have come to the conclusion as follow.
1. Water Level : After reclamation, the water-level is ascended, but the water-level is stable after dredging and changing water-course.
2. Velocity of Flow : After reclamation, back water broke out, the velocity of flow was faster after dredging and changing water-course, but the velocity of flow came to be stable in the downstream.
3. River-bed Evolution : After reclamation, the severe erosion occurred in the front of revetment, but after dredging and changing the water-course as the new stable water-course constituted, river bed evolution decreased and the flood wave flow smoothly.
4. After reclamation, the water-level remarkably increased, but the velocity of flow was nearly the same.
