  • The water level variation due to the Typhoon around the coast of Pusan in the southern sea of Korea is investigated from the observed tidal record. Water level variations at six stations along the coast are discussed in association with the meteorological data. The characteristics of storm surge at Pusan during Typhoon Thelma in 1987 is analysed using the observed data, and it is performed the numerical simulation of storm surge which includes a inverse barometric effect due to the horizontal distribution of sea sur-face pressure. From the calculation results, the peak value of storm surge in the coast of Pusan was occur-red around the 01:00 July 16th, which is well coincident with the observed water level variation at the Kadukdo. However, the calculated value at the Pusan TBM is inconsistent with the observed one, which is regarded due to a reason that the Tidal Bench Mark (TBM) locates in the channel. In the computation results, the maximum surge occurs at the coast of Nakdong estuary, which is considered primarily due to a topographic effect, and water level variation exceeded 2.5 meter in these areas while only about 60 cm in another coasts.

  • The purpose of this study is to evaluate the coastal nightscape of Yeong-Do in Busan in order to make an effective management plan of coastal nightscape. Firstly the coastal area of Yeong-Do has been divided into 8 nightscape sections. And then the nightscape images of each section have been evaluated by volunteer subjects through SD(semantic differential) analysis method.

  • Because of the increase in coastal erosion problems, many studies have been conducted to prevent coastline retreat by developing low-cost, highly effective countermeasures. We developed the artificial coral reefs (ACRs) method as part of this research trend. To verify its coastal protection performance, we carried out performance tests on its wave attenuation and beach sand capture ability, which are the key barometers for this newly developed technology. In this study, three different types of methods, including natural beach, TTP, and ACRs, were used to determine the coastal protection efficiency under both ordinary and storm wave conditions. Based on the results of this study, ACRs were found to have the best wave attenuation performance and captured more than 20% of the total erosion area. This means the ACR method can be applied as a reliable countermeasure to protect a coastal zone.

Economic Damage of Sea-level Rise and The Optimal Rate of Coastal Protection in the Korean Eastern Southern Areas (기후변화에 따른 해수면 상승의 경제적 피해비용 및 최적 해안 방어비율 추정 -동·남해안 지역을 대상으로-)

  • In this study, we are estimating the economic effects of the rising sea level due to the climate change in the Korean Eastern and Southern coastal areas. Using disaggregated regional data, we also estimate the optimal rate of coastal protection. We use FUND (The Climate Framework for Uncertainty, Negotiation and Distribution) in order to obtain estimates of the expected inundation ratios by geographical district. Our estimates suggest that in Busan the ratio of inundated land to total territory will likely constitute 3.19% by 2100, while the number in Gangwon-do province is estimated to be lower at only 0.1%. We estimate the associated economic damage to differ by geographical district with the economically active regions such as e.g. Busan and Ulsan cities, or the Gyeongsang-nam-do province, likely to sustain relatively more damage. In Busan and Ulsan where the coastal line is relatively short and the size of expected economic damage is rather high, we estimate the optimal rate of coastal protection to be at the level of 98% and 92%, respectively. In the Kyeongsang-nam-do area that is also likely to suffer a substantial economic damage due to the inundation, we suggest the optimal ratio of coastal protection to be set at the level of 78%~79%. In contrast, in the Kangwon-do province where the expected economic damage is estimated to be low, the optimal rate of coastal protection is estimated to be around 43%, depending on the scenario.

  • Marine terraces, a step-like landform, are important geologic markers that provide tectonic information during the Quaternary Period. Marine terraces are well developed along all coastlines(East, West, and South) of the Korean Peninsula, those along the East coastline are the most distinctive. The marine terraces of the East coastline are classified into 4-6 flights that are several meters or several tens of meters above the present sea level. It is believed that these terraces, except for the lowest one, were formed in the middle Pleistocene. In the base of the OSL age dating results and Blake excursion events of magnetostratigraphy, the $2^{nd}$ and $3^{rd}$ terraces are correlated to the last interglacial stage. Considering the marine terraces linked to a sea-level curve of the Pleistocene, it is thought that regional tectonic movements have uplifted the East coastal area since the middle Pleistocene. Besides, former shorelines of each terrace have varied elevations from Gangreung to Busan bay, which can be divided into four regions, namely, Gangreung-Yonghanri(I), Homikot-Najung(II), Najung-Bangeojin(III), and Waesung-Busan Bay(IV). The former shorelines of each terrace at both Gangreung-Yonghanri(I) and Najung-Bangeojin(III) are higher than those in the other two regions, due to block movements by regional faults such as the Ocheon Fault or its subsidiaries, the Gampo Lineament and Ulsan Fault. Uplift rate of the East coast ranges from 0.2 m/ky to 0.3 m/ky, but each region shows different uplift rate.

  • 임진왜란에 발생한 전투 중 부산포 해전은 이순신 장군이 일본의 근거지를 직접 공격하여 대규모의 타격을 입힌 의미 있는 해전이다. 이 연구는 임진 4차 출전 시 부산포 일대의 전투에 대하여 지금까지의 역사적 인문학적 크고 작은 성과를 종합하고 적용하여 2차원과 3차원적인 공간속에서 재현하고자 한 것이다. 이를 위하여 부산포 해전장 주변의 고지도, 조선과 왜구의 선박, 선박의 이동과 전투 시 행해졌던 진형, 그리고 사거리 등을 적용하여 입체적으로 가시화 하였다. 특히 부산성 주변 해안에 일본의 선박이 주둔한 곳을 추정하고 가시화하기 위하여 다양한 역사적 자료와 성과를 활용하는데 주목하였다

  • The coastline area, which was the important to decide the shape of the national land, has the characteristics of changing its shapes and features. We have some trouble to make the appropriate use-plan, because of the huge land to be reclaimed from the sea and developing large and small coast areas. Of them the coastal sand dune plays a definite primary role in the side of tourism and ecology. But there is not enough study for that. Busan Songdo coast is decided as an object of this study. We would analyze transfer path of the coastal sand dune through the time series analysis with RTK-GPS survey for many years. In case of Song do coast, the mean coastline length is approximately 620m, the area is approximately $31,846m^2$. Breakwaters are set up in right and left sides in Song do coast. it can make the sand dune be a minimum. So the coastal sand dune is steadily deposited with a certain beach nourishment of every year. As a result of 7 times survey, both sides of the coastal sand dune are eroded. It turns out it is going ahead over all as the center of the coastal sand dune is deposited.
