본 연구는 낙동강 진우도 자연 해빈에 내습하는 해양파랑, 해안표착물(해양쓰레기), 배후 식생대 전선의 변화 과정에 대한 상호작용에 대해서 고찰하고자 하였다. 이를 위해 해빈단면 측량, 입사파랑 수치모의실험, 해안표착물 분포 현장 조사, 자연해빈 식생대선 현장 조사 등을 수행하였다. 연구결과를 요약하면 다음과 같다. (1) 진우도 자연해빈의 지반고는 상승하고 있으며 이에 따라서 해안사구 식생대 전선도 전진하는 경향을 나타내고 있다. 지반고가 표고 1.5 m이상이 되는 상황에서 대체적으로 식생대의 전선이 외해방향으로 발달하는 경향이 강하게 나타났다. (2) 진우도 전면 수심에 의해 파랑변형된 입사파랑이 공간상으로 상이하고 소상대에서의 처오름 현상도 공간상으로 복잡한 변화를 야기할 것으로 생각할 수 있다. 해양쓰레기는 파의 처오름이 큰 경우 배후 식생대 전선에 표착물이 도달하고 그렇지 못한 경우에는 해빈상에 독립적인 섬의 형태로 표착물을 침적/퇴적시킬 가능성이 있다. 따라서 이렇게 침적된 표착물은 배후 식생대전선의 전진과 후퇴를 결정짓게 하는 요인이라 할 수 있다. 최종적으로 본 연구에서는 조사결과를 바탕으로 해안표착물과 식생대 전선의 상호작용에 대한 개념적 모식도를 제시하였다.

Recent changes in the coastal sea surface temperatures (SST) in Korea are studied by time series analysis of daily SST data during the last 60 years (1936-1995) at 18 coastal observation stations of the National Fisheries Research and Development Institute. The climate of coastal SST in Korea are rapidly changing in recent years. General trends of coast SST changes in Korea are as follows. The annual averages of SST are increasing. The annual ranges of SST variation are decreasing. The winter SST are increasing while the summer SST have a decreasing tendency. Climatic changes in coastal SST in recent 30 years (1965-1995) are more pronounced than those in the last 60 years (1936-1995). The observed trend of coast SST implies that the climate in Korea shows a tendency to shift from temperate zone to subtropical zone.

The paper presents the results of a study on the desired observing system which setting the high-level objectives for an integrated, sustained, national coastal observing system. Knowledge of the coastal zone is demanded by many constituencies, including fishermen, fisheries managers and climatologist, harbor pilots, coastal zone managers, environmental protection professionals etc. Many of these needs are being partially met by coastal zone observing system elements, both satellite and in situ. Nevertheless, these have not enough developed in an integrated manner and have been funded and operated to meet their own purpose. Thus, this study presents the development and application method for a national coastal zone observing system, which is integration of disparate observational systems and data sets to maximize their utility for many users and purposes.

Study of the background and state of Osaka's waterfront space development and analysis of the functions of 22 chosen major facilities of development project reveals the following four types: amenity-oriented development, large-scale synthesis type development, renewal compound area type development, exchange communication promotion type development. Osaka bay area has served primely as the base of harbors, industry and energy, while analysis of the ongoing project has found that the city has been making a functional transition to a type of development to live up to the needs of the times, suggesting that is wise that Korea's future direction of waterfront development be oriented toward environmental-friendly development by taking advantage of low-density area's natural resources. Given the plurality and complexity of the law of coastal zone, what is needed is a legal maintenance for coastal zone's clear-cut coordinating function and for environmental-friendly development with the limitations of seaside and coastal functions in mind.

최근 해양관련 레저 활동 및 관광의 활성화로 연안역에서의 안전사고 위험은 더욱 증가하고 있다. 그러나 현재 안전사고를 방지하기 위한 안전시설의 기술적 측면이나 관리적 측면에 대한 규정이 부재하여 연안역 안전사고 대책이 안전사고의 증가속도에 적절하게 대응하지 못하고 있는 실정이다. 연안역의 지리적, 환경적 조건은 육역과 해역의 특성이 혼재되어있으며 또한, 다양한 많은 활동(어업, 항만업, 관광, 레저)이 존재하므로 안전사고를 방지하기 위한 안전시설을 설치하는 경우에는 육역 및 해역의 특성과 어부/항만노동자/관광객/레저활동자들의 행동특성이 적절히 고려되어야 한다. 본 논문에서는 국내 및 국외(홍콩, 마카오) 실태조사를 실시하였으며, 이로부터 국내 연안역의 안전시설에 대한 현안 문제점을 제시하였다. 또한 안전시설에 대한 개선방향을 제안하였다.

This study analyzed on characteristics of the ground-water capture zone in coastal areas and mid-mountainous area according to pumping rate. For this study, it targeted Jejudo island where is the volcanic island. To analyze, MODFLOW model and MODPATH model, which are the ground-water flow analysis models, were used. As a result of research, the following conclusions could be obtained. As a result of analyzing influence of a change in pumping time upon length of capture zone, the length of capture zone in coastal area was indicated to be greater in the changing ratio compared to the length of capture zone in mid-mountainous area. Next, in the coastal area, the pumping rate and the capture-zone length are changing similarly. However, in mid-mountainous area, the length of capture zone was indicated to grow when the pumping rate comes to exceed 1,500m3/day. As a result of analyzing influence of a change in pumping time upon capture area, the tendency of a change in the area was indicated similarly in coastal areas and mid-mountainous area. Especially, it could be known that the larger pumping rate leads to the more definite increase in tendency to a change in capture area. Based on this study, it was allowed to be possibly used in the suitable pumping rate in coastal areas and mid-mountainous area of the volcano island in the future. A follow-up research is judged to necessarily analyze the influence of tubular-well group upon capture zone by additionally analyzing a change in capture zone targeting the concentrated tubular well.

In order to understand the characteristics of beach deformation, in this study, numerical simulations were conducted using a 3-D hydro-morphodynamic model (HYMO-WASS-3D) to analyze the characteristics of beach deformation due to the coastal groundwater levels. HYMO-WASS-3D directly analyzed the nonlinear interaction between the hydrodynamic and morphodynamic processes in the coastal area. The simulation results of HYMO-WASS-3D showed good agreement with the experimental results on the changes in the profile of the beach in the surf and swash zones. Then, numerical simulations were conducted to examine the characteristics of beach deformation due to the variation of the level of the coastal groundwater. As a result, the beach profiles were examined in relation to the wave breaking in the surf zone and the wave uprush and backwash in the swash zone due to the differences in the water levels. This paper also discussed the temporal and spatial distributions of the velocities, vorticities, and suspended sediments in the surf and swash zones with various levels of the coastal groundwater.

The coastal zone is the transitional area between land and sea. It plays an important role in the land-sea ecosystem. Unfortunately, most of the world's coastal areas are polluted due to the human being activities. Pollution and development are changing coastal habitats, and feeding and nursery areas are being destroyed, reducing fish and wildlife populations. The pollution in coastal areas is becoming a global environmental problem, more and more attention has been paid to coastal areas. America passed the Coastal Zone Management Act (CZMA) in 1972, and from then, CZMA outlined and conducted the National Coastal Zone Management Program and the National Estuarine Research Reserve System which including 34 projects. And England established "the Crouch & Roach Estuary Project" in 2003, and "South East Coastal and Marine Project" was started in 2007 in responding to the non-point pollutants challenge.
