  • This study was conducted as a part of investigating pre-reclamation shorelines from aerial photographs to estimate coastal land area at reclaimed lands (Anjeong industrial complex, Myeongji residental complex, and Noksan industrial complex), southeastern coast of Korea. To assess how the shorelines were suitable for the calculation of coastal lands, we constructed shoreline change data. Secondary ground control points were used to accomplish triangulation for old aerial photographs. Two kinds of shorelines were mapped; one was the shoreline based on approximately highest high water level (AHHWL) and the other was the high water line based on wet/dry signiture. These shorelines were consistent at artificial coast. Shoreline change data were built with a variety of levels of error due to detailed differences in the photograph scale, quality of image, type of ground control point and type of shoreline. Thus assessment of the pre-reclamation shorelines at the level of qualitative analysis for the trend of shoreline changes was satisfactory. Most of shoreline changes before reclamation in this study were associated with coastal development. Investigation of shoreline attributes in relation to aerial photographs allowed us to understand the shoreline changes.

  • In this paper, we discussed methods and problems for estimating historical shorelines on a reclaimed land. Since many of coastal lands are unregistered in Korea, reclamation of public waters could cause complicated land ownership dispute. Unlike cadastral boundaries, historical shorelines can be represented by those of various locations due to lack of legal definition of shoreline as well as characteristics of shoreline changes, which directly influence on the calculation of coastal and submerged land areas. Through a case study for Anjeong industrial complex, a systematic method of investigating historical shorelines was suggested to resolve the problems. For a rocky coast where shoreline changes are not likely to occur, a shoreline based on tidal datum was retrieved using aerial photographs taken before the construction of reclamation. Compared with ground survey data, the shoreline was accurate, indicating that the digital photogrammetry was reliable.

  • Recently, coastal damage according to the natural disaster like storm-surge, overflowing of the sea has been massively increased. In case of earth fill at the seaside, there are a lot of weak areas of the natural disaster and it has also high possibility that a large disaster happens. Thus flood expectation map in the reclaimed land using 3D spatial information was produced in this study. The area around Myungji, Kangsugu, Busan which was made with the large scale earth fils at the seaside was designated as a study area. Observation of both costal datum and ground height using the tidal date and field surveying dates was conducted. Terrain model using the GIS program was produced and than 3D building model was produced using 3D MAX. It was shown that there are possibility more than 50% if over 4.5m storm-surge is happening, as a result of calculating the virtual flooded area on the produced cartographic map.

  • Busan has its unique character which differed from inland such as Seoul and Daegu Because Busan is located in coast district of Korea, it could be inferred that the climate change in Busan had been influenced by foreshore reclamation in the urbanization process. The purpose of this study is to investigate the relationship between reclamation of the foreshore and climate change by analysing the climate change over the past 70 years in three metropolitan cities. The conclusion from this study are as follows. 1) There was not a big difference among elements of climate change in three cities. 2) Annual mean minimum temperature in Seoul and Daegu had remarkably increased over the past 70 years. On the other hand, annual maximum temperature in Busan had a sudden rise in the only tome to reclaim the foreshore.

  • 해안의 연약지반에 건설되는 폐기물 매립지는 매립지의 안정성 평가를 위하여 하부기초지반의 침하거동 특성에 대한 분석이 필요하다. 본 연구에서는 현장 침하계측자료를 이용하여 현장 간극비와 현장 압축지수를 역산하여 그 특성을 분석하였다. 그 결과 매립초기에는 상부하중에 의한 유효응력증가가 미소하여 하부기초지반은 과압밀 특성을 나타내고 현장 압축지수 변화가 미소하였으나, 매립이 진행될수록 상부하중이 선행압밀하중을 초과하여 정규압밀영역으로 변화함에 따라 큰 폭의 증가를 보였다.

  • In this study we predicted some of the negative effects on the ocean ecosystem and water quality, caused by a coastal reclamation project in semi-closed bay that makes it extremely difficult to be purified by natural process. In order to predict change of water quality triggered by coastal reclamation, the 3D hydrodynamic model and material cycle model are used. And we suggested new ecological park, an artificial beach and eco-friendly revetments on the reclamation area to mitigate the environmental impacts affecting this area using the numerical simulation results and observation data.

  • 거주지나 공장부지와 같은 이용 가능한 토지를 만들기 위하여 해안 지역을 매립하는 토목공사가 전세계 곳곳에서 이루어지고 있다. 매립공사에서 매립토량의 결정은 경제성 부분에서 매우 중요하나 국내는 어항 항만 설계기준(2014)에 의하여 단순히 입경별로 유실율과 유보율을 산정하여결정하고 있는 실정이다. 따라서 본 연구에서는 원형의 매립호안 주변의 유사 거동을 분석하기 위하여 수리실험을 통한 연구를 진행하였다. 수리실험은 길이 13.0 m, 폭 5.0 m, 수위 0.10 m의 직사각형 단면의 개수로에서 수행되었으며, 실험에 사용된 유사는 주문진사($d_{50}=1.0mm$)와 안트사이트($d_{50}=0.44mm$)를 사용하였다. 원형 호안은 방수처리가 되어있는 목재로 제작하였고 두 가지 유사 모두 매립지역에서 형성되는 모래의 형상은 차이를 보였고 일정량의 유사가 호안 하류측에 쌓이는 것으로 나타났다. 선행 연구와 달리 호안에서 형성되는 모래의 이송된 형상을 관측하였다. 향후 모래 유입 위치를 달리하여 퇴적된 모래의 형성을 정량적으로 관측이 가능하다면 매립공사의 경제성을 높일 수 있을 것이라 기대된다.
