A Study on the Characteristics of Water Quality in the Jinhae Bay

The Korean Peninsula is surrounded at three sides by seas and is located at the center of the Asian-Pacific area. Its southern coast area is the important place where Pacific Ocean and Asian Continent connect. In the area of Jin-hae Bay, in order to develop the Pusan Port into an international transportation center, the New Pusan Port is under construction at Gaduk-Do. In this era, with the industrialization of Jin-hae Bay area, every year industrial waste water and sewage is discharged into the bay which causes red-tide. So we need to make efforts to prevent the damage of red-tide resulting from the industrialization and to improve the water quality of the bay. Jin-hae Bay sustains damage from red-tide every year. So in order to know the characteristics of water quality in this bay, the water quality environment was investigated. The sea movement characteristics, after getting knowledge of the tide and current characteristics, was known by establishing the numerical model and executing the sea movement simulation. And to get the characteristics of water quality environment in this area, the water quality simulation and investigation were executed. The investigation results and the simulation results were compared and analyzed. This study is divided into three steps: The first step : in order to examine the natural environment, the natural conditions such as weather condition, ocean condition and so on have beeb collected and analyzed. The second step : the spot-investigation of the water quality environment of Jinhae Bay was conducted and analysed. The third step : the sea movement simulation was conducted and the pollution-spreading simulation by using of the calculated flowing data was carried out.표목차 ⅲ 그림목차 ⅴ ABSTRACT ⅷ 제1장 서론 1 1.1 연구의 배경 1 1.2 연구의 목적 2 1.3 연구의 내용 및 방법 3 제2장 부근해역의 지리ㆍ환경적 특성 5 2.1 지형 5 2.2 기상 5 2.3 파랑 21 2.4 조석 및 조류 22 2.5 수질 27 제3장 수질환경 및 해양생태계 조사 47 3.1 조사개요 47 3.2 조사일시 47 3.3 조사지점 조사항목 및 조사과정 48 3.4 조사결과 52 제4장 해수유동 시뮬레이션 64 4.1 실험내용 64 4.2 수치모형의 구성 65 4.3 모델의 검증 71 4.4 수치실험 결과분석 72 제5장 수질확산 시뮬레이션 78 5.1 실험내용 78 5.2 수치실험 및 분석 79 제6장 결론 84 참고문헌 8

A Study on Cost and Benefit Model for the Operational Effect of Maritime Traffic Safety Facilities

In this research, firstly, the analysis of domestic and foreign instances, the functions for maritime safety facilities, the maritime traffic survey, the statistical survey for maritime traffic data and the statistical survey for marine accidents have been done in order judge the economical efficiency of maritime traffic safety facilities from the sides of economical and effective analysis against the investment of public works. And the analysis of operation-effectiveness was carried out under applying in actual maritime traffic safety facilities after constructing a Cost and Benefit Analysis for the operational effect. The method and process of evaluation used the quantitativeevaluation method which is possible and the case where quantitative evaluation method is difficult applied the qualitative evaluation method. In this case, it is evaluated on the basis on an objective information and data or fact, which is possible. The processes of evaluation were divided by 3 phases. The phase 1 is the pre-evaluation that is done before establishing a maritime traffic safety facility. The phase 2 is post-evaluation that is done after establishing a maritime traffic safety facility. The phase 3 is re-evaluation that it follows the alteration and improvement in change of the legal and technical environment. And an analysis for the operational effectiveness will be practically carried out. The cost and benefit model for the operational effect was established by classifying the transportation, safety and other benefit. The loss evasion expense which it follows in marine accident decrease was changing at monetary value, and the safety benefit was produced from it. By calculating navigational time, the operation timely shortening ratio which it follows in decrease of navigational time and an operational curtailment expense produced as the transportation benefit. With the technical advance, the existing maritime traffic safety facilities are changed in demand of the new equipment. Other benefits were produced from the different characteristics between the old and new. The method that each item became quantitative proposed. The proposed cost benefit model was applied with the evaluation for Incheon tidal current signal station, Mokpo Aton monitoring and control center and Jindo coastal VTS system after producing the benefits and calculating the costs. The all results of cost-benefit were bigger than 1 and the all net present value were bigger than 0. And the economic internal benefit rate came out a large scale compared to the social discount ratio. It is likely that it was evaluated that it has propriety economically.목 차 ⅵ ⅸ xⅳ Abstract xⅵ 제1장 서론 1 1.1 연구의 배경 및 목적 1 1.2 연구의 방법 2 1.3 연구의 동향 3 1.4 연구의 내용 5 제2장 해상교통안전시설의 운영효과에 대한평가방법 및 절차 8 2.1 평가방법 및 절차 8 2.1.1 사업평가 8 2.1.1.1. 사업평가의 의의 8 2.1.1.2 사업평가의 목적 9 2.1.1.3 사업평가의 종류 9 2.1.2 사업평가의 기본 구조 10 2.1.2.1 평가의 개념 11 2.1.2.2 평가의 대상 11 2.1.3 운영효과의 평가 방법과 절차 12 2.1.3.1 평가의 방법 12 2.1.3.2 평가의 절차 13 2.2 운영효과 분석 사례 14 2.2.1 국내의 운영효과 분석사례 14 2.2.2 국외의 운영효과 분석방법 및 사례조사 23 2.2.2.1 유럽 수역 연안 VTS의 비용-편익 23 2.2.2.2 미국연안경비대에 의한 선박교통관리서비스(VTS) 비용효과분석 42 2.2.2.3 전자해도와 항해통합시스템 도입의 안전이익 분석 46 2.2.2.4 인도네시아공화국 항행원조시설 정비 기본계획보고서 49 2.2.2.5 국제항로표지협회 업무 매뉴얼 50 2.3 요약 51 제3장 해상교통안전시설의 편익산출모델의 수립 52 3.1 해상교통안전시설의 특성 52 3.1.1 해상교통안전시설의 종류와 기능 53 3.1.1.1 광파표지 54 3.1.1.2 전파표지 58 3.1.1.3 음파표지 59 3.1.1.4 특수시호표지 59 3.1.1.5 집약관리시스템 60 3.2 해상교통안전시설의 편익산출모델의 수립 61 3.2.1 편익산출모델수립의 기본원칙 61 3.2.2 편익산출모델의 수립 62 3.2.2.1 안전편익의 산출 63 3.2.2.2 수송편익의 산출 86 3.2.2.3 기타편익의 산출 98 3.2.3 비용의 산정 98 3.2.3.1 비용항목의 추출 98 3.2.3.2 비용의 산정 100 3.2.4 잔존가치의 산출 102 3.2.5 비용편익분석 103 3.2.5.1 기본원칙 103 3.2.5.2 비용편익분석의 실시 105 3.2.6 효과의 산출 109 3.2.6.1 기본원칙 109 3.2.6.2 항해자의 심리적 부담 경감효과 산출 109 3.2.6.3 CVM에 의한 항해자의 심리적 부담 경감효과 산출 112 3.2.7 민감도분석 114 3.2.7.1 기본원칙 114 3.2.7.2 민감도분석 실시 115 3.2.8 의사결정의 기준 116 3.2.9 분석결과의 종합 117 3.2.9.1 비용편익분석의 요약 117 3.2.9.2 분석결과의 정리 122 3.2.9.3 운영효과분석의 총괄표 125 3.3 타 모델과의 비교 검증 128 3.4 요약 132 제4장 운영효과의 편익산출모델 적용 134 4.1. 조류신호소 135 4.1.1 인천조류신호소의 개요 135 4.1.2 인천항 주변의 자연환경23)~32) 135 4.1.2.1 평균 풍속 135 4.1.2.2 폭풍 136 4.1.2.3 태풍 137 4.1.2.4 안개 138 4.1.2.5 강수 138 4.1.2.6 조류 140 4.1.2.7 파랑 141 4.1.2.8 자연환경의 종합적 특징 142 4.1.3 인천항의 교통 및 해양사고분석 142 4.1.3.1 교통량 현황 142 4.1.3.2 교통량 추정 145 4.1.3.3 해양사고 조사 분석 148 4.1.4 비용편익 산출의 적용 152 4.1.4.1 안전편익의 산출 152 4.1.4.2 기타편익의 산출 155 4.1.4.3 잔존가치 156 4.1.4.4 비용항목 157 4.1.4.5 계산기간과 사회적 할인율 159 4.1.4.6 평가지표 160 4.1.4.7 운영효과분석 총괄표 163 4.1.5 운영효과편익산출의 적용결과 164 4.2 집약관리시스템 166 4.2.1 목포집약관리시스템의 개요 166 4.2.2 목포항 주변의 자연환경23)~32) 166 4.2.2.1 평균 풍속 166 4.2.2.2 폭풍 167 4.2.2.3 태풍 168 4.2.2.4 안개 168 4.2.2.5 강수 169 4.2.2.6 조류 171 4.2.2.7 파랑 172 4.2.2.8 자연환경의 종합적 특징 172 4.2.3 목포항의 교통 및 해양사고분석 173 4.2.3.1 교통량 현황 173 4.2.3.2 교통량 추정 176 4.2.3.3 해양사고 분석 177 4.2.4 비용편익 산출의 적용 181 4.2.4.1 안전편익의 산출 181 4.2.4.2 기타편익의 산출 184 4.2.4.3 비용항목 186 4.2.4.4 계산기간과 사회적 할인율 187 4.2.4.5 평가지표 187 4.2.4.6 운영효과분석 총괄표 190 4.2.5 운영효과편익산출의 적용결과 192 4.3 연안VTS 193 4.3.1 진도 연안VTS의 개요 193 4.3.2 자연환경23)~32) 193 4.3.2.1 평균 풍속 193 4.3.2.2 폭풍 194 4.3.2.3 태풍 195 4.3.2.4 안개 196 4.3.2.5 강수 197 4.3.2.6 조류 199 4.3.2.7 파랑 199 4.3.2.8 자연환경의 종합적 특징 200 4.3.3 교통 및 해양사고분석 201 4.3.3.1 교통량 현황 201 4.3.3.2 해양사고 조사 분석 203 4.3.4 비용편익 산출의 적용 206 4.3.4.1 안전편익의 산출 206 4.3.4.2 수송편익의 산출 209 4.3.4.3 잔존가치 213 4.3.4.4 비용항목 213 4.3.4.5 계산기간과 사회적 할인율 215 4.3.4.6 평가지표 216 4.3.4.7 운영효과분석 총괄표 220 4.3.5 운영효과편익산출의 적용결과 222 4.3.6 다른 모델과의 비교 223 4.4 요약 225 제5장 결 론 228 참고문헌 23
