  • 본 논문에서는 태풍으로 생기는 폭풍 해일에 취약한 연안 지대의 위험도 분석을 다루고 있다. 그리고 대상 지역을 상습적인 폭풍 해일로 인한 피해가 상습적으로 일어나는 마산만 지역으로 설정하였다. 이 마산만 지역에서 폭풍 해일로 인하여 생기는 연안의 주요 시설에 대한 피해를 물에 잠기는 정도를 중심으로 분석하여 재산피해의 정도를 산정한다. 그리고 이렇게 분석된 재산피해액 자료는 합당한 방재 정책을 결정하는 데 적절히 활용될 것으로 기대한다.

  • Typoon Maemi landed on the southern coast of Korean Peninsula at 21:00, September 12, 2003 with a central pressure of 950 hPa. A three dimensional (3D) inundation model was established to calculate the storm surge and flooded area due to Typoon Maemi. A field survey of storm surge traces in Masan City was carried out to evaluate the inundation water depth. Hydromet-Rankin Vortex model was used to calculate the atmospheric pressure and the surface wind fields. The inundation area, storm surge and typoon-induced current were calculated using the 3D model. The peak of computed storm surge in Masan Port using the 3D model was 238 cm, and the observed peak was 230 cm. The simulated storm surge and the inundation area showed good agreement with field survey data. The comparison of the 3D and the two dimensional (2D) models of storm surge was carried out, and the 3D model was more accurate. The computed typoon-induced currents in the surface layer of Masan Bay went into the inner bay with 30~60 cm/s, while the currents in the bottom layer flowed out with 20~40 cm/s.

  • Fishing, aquaculture, coastal tourism and port activities in southern coastal seas are important to the Korean economy Conventional strategies or quick-fixes may not be the best means of addressing coastal issues. Coastal issues in Korean coastal sea include harmful algal blooms (HAB), oxygen depletion, and sea grass disappearance. Regional coastal management plans have been developed during 2001~present after inauguration of Coastal Management Law in 1999. Activities such as eco-pioneer cities, pollution reduction, constitutional rearrangement, environmental regulation, monitoring indicators, and budgeting would be included in regional coastal management Planning. The successful implementation of integrated coastal management is largely dependent on the engagement of government and non-government organizations to increase the chorus of concern. The need to involve coastal area residents in restoring activities was addressed with the creation of NGOs' Association for Masan Bay Restoration (NAMR). Several restoration efforts by NAMR are currently underway in Masan Bay coastal zone with scientific and local knowledge. A new level of dialogue was achieved suggesting a sustainable picture of Masan Bay coastal area regarding to a new port construction.

  • Masan Bay is a typical enclosed coastal sea and receving body of discharges from Masan city and Changwon city. A POTW(Publicly Owned Treatment Works) started operation from November 1993 when the population of drainage area increased abcent 1.0 million and the effluent from this Plant has being discharged to the enclosed sea where is located at 15km distance from inner Masan Bay. Thus the inflow pattern to Masan Bay has been changed. The main objective of this research is to evaluate the relationship between urban wastewater discharge and water qualify change in a typical coastal zone. It is necessary a) to evaluate the change of input loadings, b) to determine the effect on water quality changes, and c) to find the respective importance of improvement options that must be controlled in the wastewater treatment plant. It was concluded that the sea water quality has being adversely affected by the discharge of insufficiently treated urban wastewater and the nutrient removal in wastewater treatment was very important and urgent.

  • This study aims to develop the Masan bay special management system of the point and nonpoint sources of pollution using GIS as part of the Integrated Management System of the Masan Bay Special Management Area and utilize Total Pollution Loads Management System in Masan Bay more systematically and scientifically. The result of the pollution sources management at the Masan bay in conjunction with GIS was made possible the comparison of the source of pollution and the pollutant load among each administration area. It also developed Arc-GIS watershed management program which enables to estimate the population for discharge facilities, the water use of domestic population and commercial population, and pollutant load and discharge load of COD, TN and TP by the administration areas, years, and usages. In addition, this study anticipated minimizing temporal, economical efforts in utilizing large amounts of property and space utilization data and expediting the decision making process of policies in relation to the systematic and effective management system of pollutant loads at the Masan bay area. Further studies are required to plan the systematic management of the point and nonpoint sources of pollution and complement the watershed management system using GIS program for pollutant load which enables to predict the current and future state of point and nonpoint sources.

  • 연안해역에서의 흐름은 조석에 의한 주기적인 해수면의 승강작용에 의한 조류, 바람에 의해 발생되는 수면 마찰력에 의한 풍성류(wind-driven flow), 밀도가 다른 하천수 등의 유입에 의한 밀도류 등에 의하여 발생한다. 대부분의 자연수괴에서의 실제 흐름은 이러한 흐름들이 단독으로 발생하는 것이 아니라 동시에 발생하는 복합류(combined flow)이다 따라서, 연안해역에서의 오염물질의 이동ㆍ확산은 이러한 복합류에 의하여 발생하므로 복합류의 구조에 대한 정확한 이해, 평가 및 예측은 연안수의 순환 및 오염물질의 확산에 관한 자연현상을 정확히 이해하는데 있어서 반드시 필요하다.

  • The difficulties to build a 3-dimensional water quality model for the coastal water quality improvement and the environmental recovery estimation are the lack of periodic observed data and the many problems to observe continuously. I observed the rainfall and non-point pollutants outflow patterns in Jinhae-Masan basin as mid-step researches for the water quality simulation and management method development in a coastal area. I applied Landsat image system and Geographic Information System to analyze the runoff and non-point pollutants outflow patterns. A water quality simulation model (SWMM) applied to Jinhae-Masan basin with results of the land use distribution, non-point pollution loads, and watershed informations from GIS(IDRISI used). I proposed some improved survey and GIS application methods reflect upon the pollutant characteristics from the observed non-point pollutant outflow patterns.

  • 최근 연안해역은 산업화와 도시화에 의해서 각종 오염물질에 의해 오염이 심화되고 있는 실정이다. 특히 산업화에 의해 생성되어 해역으로 유입된 중금속 원소들은 이온세기가 강한 해수와 혼합되면서 입자물질에 흡착되어 저층퇴적물로 침강 제거된다. 그러므로 산업화에 의한 영향을 받는 공단주변 해역의 퇴적물은 퇴적물의 자연적인 함량보다 높은 농도를 보일 것이다. 이러한 산업화된 해역에서 중금속의 오염정도를 파악하기 위해 울산 및 마산만 일원의 해저퇴적물을 1999년 9월에 채취하여 분석하였다. (중략)

  • The discharges of groundwater flow were estimated using Darcy's method along the coastal zone in the Masan Bay. The estimates using the information, i.e., groundwater level, location of the observation well, hydraulic conductivity, the thickness of the aquifer, and coastline length, were 1.65% of the precipitation of the watershed. The estimated groundwater discharges through fractured rock aquifer and the aquifer with sedimentary material were $0.7\times10^4$$m^2/year$and $1.0\times10^7$$m^3/year$ respectively. Whereas, the discharge estimated by KORDI (2003) using isotopes method is about 20 times larger than the estimates from this study because of the influence of the re-circulated seawater through the coastal zone aquifer. In order to quantify this effect in detail, the groundwater levels and salinity changes in the observation wells located in the coastal zone should be continuously monitored and analyzed.
