지구온난화에 따른 연안의 해수면 상승은 해안에 가해지는 파랑에너지의 상승을 유발한다. 이러한 해수면의 상승은 상대적으로 수심이 깊어지는 효과를 초래하고 이는 과거 발생하지 않았던 해안지역의 침식 및 해빈에서의 모래를 유실시킨다. 특히, 국내 연안 225개소의 연안 모니터링 결과 142개소인 62%가 침식우려 이상의 등급으로 나타났다. 일반적으로 연안침식에 대응하는 방법은 호안을 쌓아 보호하게 되는 경성공법으로 외력의 변화에 따라 현장여건에 맞는 호안의 경사, 단면형상 및 재료를 선택하게 된다. 하지만 현상에 대한 불충분한 이해에 근거한 공법 적용으로 제반국가에서 다양한 피해가 발생하고 있으며, 이는 공법신뢰도 향상을 위한 기술개발 및 융합기술 도입의 필요성을 보여준다. 본 연구는 파랑저감에 효과적인 다공성 구조물Biocoast를 활용하여 해안침식피해억제를 위한 친환경 투수 바이오 콘크리트 블록을 개발하였다. 특히, 자연해변 및 호안시설에 대해 자연 및 인위적 외력에 의한 침식과 세굴로부터 연안을 보호하고, 블록의 유닛화를 통해 품질관리 및 공정관리의 효율성을 향상시킬 수 있을 것으로 사료된다.

The changes of sea bottom configuration, which may cause the coastal disasters, have been considered as social problems. It is obvious that the beach deformation is attributable to the sediment transport associated with erosion and siltation in coastal areas such esturies, channel and harbors. The prediction method and countermeasures far them, however, are not on the level of satisfaction, which indicates that make efforts should be made on developing them. Groin was constructed at Hak-Dong gravel beach to embark ship at 1996, as a result region of right of groin, severe erosion of beach is proceeding till now 1999. In this study, based on the field measurements, involved the one-line theory model which was selected for the prediction of shoreline change to prepare coastal protection methods of Hak-Deng gravel beach. Author found that the storaged sediment estimation model by Sonu and Beek(1971) is useful model at the Hak-Dong gravel beach by the use of topographical survey data from September, 1998 to September, 1999.

In this paper I tried to find out changed and improved streetscape through the simulation using components of streetscape abstracted by factor analysis after analyzing present situation and problems of the streetscape for housing developments prepared on publis water surface. An analysis object is located in Haeundae Marine City in Busan. As a result of analysing the streetscape of marine city at present, I could see that main problems were discontinuous street space that did not reflect the characteristic of seashore, uncomfortable and insecure passage owing to coexistence street at seashore, insufficient street facilities for pedestrians, and disordered outdoor signboards. Therefore, I put the causal problems of marine city's streetscape in the insufficient street components, disharmony, and discontinuity so analysed the simulation elements applying selected street components and evaluated them to deduce demand factors having common meaning. As the result, the common demand factors were 'street furniture', 'harmonious streetscape with surrounding', 'landscape with natural openness', and 'landscape with dynamic symbol' in the order. So it needs to stress on a plan for proper arrangement of 'street facilities' and symbolic streetscape having continuity and harmony with surrounding so that the plan can proceed more properly for marine city's identity.

Every coastal area exhibits its own unique landscape owing to the combination of the natural and cultural processes. Coastal barrier islands well show the cultural aspects of American coastal landscapes. Some 47% of barrier island area was occupied by urban and built-up area in New Jersey, while some 5% in Georgia. Tourism-related development is back to in the mid 19C. in N.J. due to the closeness to heavily populated areas such as New York and Philadelphia. Developments without proper understanding the nature of coastal processes caused New Jerseyization, the destruction of the beauty or naturalness. It was mainly due to the lack of growth-control policies and the foresight for the future coast in the processes of legislation. North Carolina's islands experienced an increase of 269% in urbanized acreage between 1956 and 1976. However, N.C. exercised her wisdom to recover the naturalness of the coastal environs: all engineering structures are banned on the beaches. Nine out of 13 barrier islands in Georgia exist in the wilderness condition owing to her unique history. The remaining islands still experienced the least development. After the Civil War most of Georgian islands were owned by rich families and maintained as wilderness. In the 1970s most of the uninhabited islands were sold or donated to research institutes or governmental agencies.

강화도는 '지붕없는 박물관'이라 불릴 만큼 선사시대부터 조선 시대까지 많은 문화유산과 역사적 유적지가 보존된 곳이다. 선사시대의 고인돌과 단군왕검께서 하늘에 제를 올리던 참성단을 비롯되어 고려 시대에는 대몽항쟁 39년간의 도읍지로서 팔만대장경판각, 고려청자, 금속활자 주조 등 민속 문화의 황금기를 꽃 피워 온 산실이며, 조선 말기에는 병인양요, 신미양요, 운양호 사건과 강화도 조약 체결 등 외세 열강의 침입에 의연히 맞서 싸웠던 국난극복의 현장이기도 하며 방위를 위한 5진7보53 돈대(墩臺)가 강화도 해안가 전 지역에 분포되어 있다.

제주도는 한반도 남방 해상에 해당하는 $120^{\circ}$ 16'~$126^{\circ}$ 57'에 위치하는 화산섬이다. 이 섬의 동북지방에 있는 만장굴은 북제주군 구좌읍 동금녕리에 위치하며 오늘날 화산동굴로는 세게 제5위에 해당하는 8,924m의 화산동굴(용암굴)이다. 실지로 이 만장굴을 중심으로 산위로 또는 산밑해안가로 뻗고 있는 같은 화산 활동시기에 같은 용암류가 형성시킨 많은 동굴들(김녕사굴, 밭굴, 전굴 그밖에 개우샛굴, 덕천굴 등)을 포괄시킨 만장굴 동굴시스템(동굴계)로 따지면 실로 세계 제일가는 협재동글시스템(11,749m) 다음가는 세계 제2의 화산동굴시스템(13,268m)으로 현재까지 국제적인 인정을 받고 있는 동굴군이다.(중략)

The study area is located on the western coastal region of Korea, partly had been reclaimed lands. Groundwaters of the coastal area show lower Eh and DO values (Eh: 0.57 V ${\rightarrow}$ 0.13 V, DO; 9.7 mg/l ${\rightarrow}$ 1.3 mg/l), and higher Fe concentrations (> 20 mg/l) than those of the inner land (< 0.3 mg/l), indicating that the redox condition of groundwater changes from oxic into suboxic/anoxic conditions as it flows from the inland toward the coastal area. In addition, Fe speciation of groundwater from the coastal area demonstrates that the most dissolved Fe exist as $Fe^{2+}$, reflecting that groundwater is under the anoxic condition to sufficiently occur Fe reduction. According to the result of Fe extraction with the sediment samples from three wells (A, B, C), the sediments provide enough $Fe^{3+}$ to occur the Fe reduction in the groundwater. Integrated all results of the groundwater and sediment, we infer that the Fe reduction to occur in groundwater is associated with the reclamation processes of the study area.

중국 동북부와 일본 혼슈 및 한국에 주로 분포하는 동아시아종으로서 우리나라에서는 해안가를 중심으로 전남 완도와 충남 안면도, 경기 백령도, 경남 등 도서지방과 경북 포항부근 등에 작은 집단을 이루며 분포하는 희귀식물이다. 과거에는 자생지가 잘 알려지지 않아 천연기념물로 지정된 안면도 모감주나무 군락에 대해 원산지 논란이 일기도 했었다.(중략)

인간이 직면하고 있는 대부분의 문제들은 시대적인 산물일 것이다. 인간들은 경제행위를 하기위해 주변의 자연과 환경을 그 시대적 배경과 역사적인 발전단계에 따라 여러 가지 형태로 변화시켜 왔다. 처음에는 가장 기본적인 욕구를 충족시키기 위해 인간은 강이나 하천 또는 해안가와 같이 물에 쉽게 접근할 수 있는 곳에 정주공간을 형성하였다. 그러나 어느 순간부터 인간은 그 같은 자연자원의 단순한 사용자로부터 그 자연자원을 필요에 따라 변화시키는 지배자가 되었다.(중략)

The Haean basin is a unique geographical feature formed by differential erosion and it borders the military demarcation line. Recently the basin has become an interest of civilians due to security tour, highland vegetables and wetland. After the civil war, the population decreased but it has increased since 2007. The annual mean air temperature in the basin has increased with a rate of $+0.016^{\circ}C/yr$ and the annual precipitation also has increased with a rate of +10.41 mm/yr. The precipitation occurring in June~August (wet season) occupied most of the total precipitation increase. In addition, recently the number of groundwater wells and its use have gradually increased and most of them are for agriculture including cultivation of rice and highland vegetables. If the air temperature further increases in the future according to the climate change scenarios, the highland vegetables cultivation will be difficult. Furthermore, if the rainstorm in the summer will be enforced, the groundwater recharge and water management will be aggravated. Therefore, an evaluation for sustainable groundwater development in the basin and a reform of the current agriculture (change of cultivating crops) depending on much water are essentially required.
