    Abstract PDF
    The air quality modeling was carried out to assess the impact of air quality for large scaleurban development. The site for the assessment is Multi-fuctional Administrative City whichlocates in Yeongi-gun, Chungcheongnam-do and estimated population in 2030 is 500,000.Two automatic weather monitoring stations were installed to monitor the meteorologicalvariables for a year and upper air meteorological parameters were measured using radiosondefor 5 days with 4 hours interval in every season. The air quality of standard air pollutants werealso measured for 5 days continuously in every season.The results of wind field analysis based on the site measurements and CALMET modelingshowed that the valley and mountain winds were prevailed when the sypnotic wind was weak.It also showed that wind speed and directions were highly space-variable within the site basin.The variable wind characteristics implies that the Gaussian dispersion model such ISC3 andAERMOD are not appropriate and the unsteady-sate Lagrangian model such as CALPUFF ispreferable.CALPUFF model was applied to assess air quality impact of new sources. The new sourceswere those for individual and group heating facilities as well as the traffic increases. The resultsshowed that the estimated concentrations of CO and SO2 pollutants by summing the impactconcentration of new sources by the dispersion model and the ambient air concentrations by thesite measurements were acceptable but those of PM-10 and NO2 would violate ambient air quality standards at several locations due to high ambient air concentrations. It is recommended that the emission reductions near the site should be enforced to improve the ambient air quality.

    Jintaek Hong , Kim Hai Gyoung , Kangho Oh and 6 other persons | 2007, 16(6) | pp.393~405 | number of Cited : 6
    Abstract PDF
    To examine the sedimentary geochemical characteristics of sediment in the Tamjin River andDoam bay, the analysis was conducted, using the sample obtained in February 2000, on thegrain size and the contents of metallic elements and organic carbon. The factors that influencethe geochemical behavior of metallic elements in the surface sediment are grain size, organism,surrounding soil and CaCO3. To find out the pollution level of metallic elements, theenrichment factor (EF) and the index of geoaccumulation (Igeo) were researched. The majority ofmetallic elements sustain their values in natural state. The elements such as K, Ba, Zr, etc.appear to be rich in some places. The EFand Igeo of P, Cu, Zn, and Pb, which belong to toxicheavy metals, are partly related with man-made pollution. P and Cu have a high EF, Pb has ahigh I geo and Zn is high in both EFand I geo. The low contents of P and Cu are not likely to berelated with the pollution of water environment. However, given the development of relativepollution, the research and the management regarding the pollutants are needed. Because Pb,naturally enriched by geological characteristics, has a large influence on water environmentalong with Zn, the adequate measures against man-made pollution should be worked out.

    박선환 , Yoon-Young Chang , 강형식 and 2 other persons | 2007, 16(6) | pp.407~419 | number of Cited : 2
    Abstract PDF
    This study investigated the predicted and abserved outflow of groundwater which occurredduring tunnel constructions. Among the 586 road construction projects from 1986 to 2006, 4route 25 tunnel construction areas and 26 waste water treatment facilities under constructionwere studied.Most of the tunnel outflow prediction in EIA (Environmental Impact Assessment) processhave been classified into the 17 types of units depending on the assessor’s options, which havenot conformed to the request of the residents and non government organizations.The investigation results showed that the outflow of underground water in tunnelconstruction areas averaged about 0.133m3/km · min with the maximum 0.386m3/km · min,and that the outflow mostly occurred in the early stage of tunnel excavation and diminishedgradually. The prediction of outflow of underground water in the EIA process showedexcessive results compared to observed outflow, the even 51.7 times.Consequently for more realistic prediction, current EIA method for prediction of outflow ofunderground water in tunnel construction areas has to adopt numerical methods coupled withhydraulics and geologic informations from unit methods of present time.

    Study on the Temporal and Spatial Variations of Salinity by Freshwater Discharge in Gyeonggi Bay

    정정호 , Yoon-Young Chang , 김국진 and 3 other persons | 2007, 16(6) | pp.421~432 | number of Cited : 3
    Abstract PDF
    To investigate temporal and spatial variations of hydrodynamics and environmentalconditions in Gyeonggi Bay, including Han River estuary, numerical experiments wereperformed using 3-dimensional fine grid numerical ocean model. The model successfullyreproduced the physical phenomena already known in Gyeonggi Bay where tide and freshwater discharge are dominant forcings.The calculated harmonic constants of tide and tidal current agreed well with those ofobservations at nine tide stations and two tidal current stations. Tidal asymmetries along theYeomha Waterway, mainly caused by non-linear effect, were well reproduced and agreed wellwith observations. Time series of salinity at four stations(A, B, C and D) and horizontaldistributions of monthly averaged salinity show that Gyodong and Seokmo Waterways play animportant role in fresh water discharge into the Gyeonggi Bay rather than Yeomha Waterway.

    환경영향평가는 대규모 개발사업을 대상으로, 계획 확정후 사업 실시단계에서 개발사업 시행에따른 환경영향 저감방안을 중점 검토하는 제도인데, 사전환경성검토는 행정계획과 환경상 민감지역의 소규모 개발사업을 대상으로, 계획 확정 이전단계에서 환경적 측면에서 입지나 개발의 적정성·타당성을 사전에 검토하는 제도이다.사전환경성검토는 2006년 6월부터 대상 행정계획을 구체적 개발사업의 상위 행정계획으로 확대하고, 계획의 적정성, 입지의 타당성을 미리 검토할 수 있도록 하고, 검토과정에서 주민, 전문가, 시민단체 등 이해관계자의 의견수렴을 거치도록 하는 전략환경평가 체제로 개편됨으로써, 환경갈등이나 사회·경제적 문제를 예방할 수 있는 기반을 보다 강화하였다. 환경부 주관의 사전환경성검토가 전략환경평가를 강화하는 동안 건설교통부가 중장기기본계획에 대한 전략환경평가를 시행하기 시작하였다.우리나라의 전략환경평가는 건설교통부와 환경부가 전략환경평가를 별도로 운영하는 데 따른 비효율성, 국토계획과 환경계획의 연계성 부족, 선거공약으로 제안된 대규모 개발계획 등에 대한 객관적 환경평가의 어려움 등의 문제를 가지고 있다.따라서 본 연구는 전략환경평가제도의 정립을 위해, 환경정책패러다임의 변천, 환경영향평가와사전환경성검토의 발전, 전략환경평가의 현황과 선거공약으로 제안된 대규모 개발계획에 대한 전략환경평가의 한계 등을 고찰한 후, 전략환경평가제도의 발전방향과 개발계획과 환경계획의 연계통합방안을 모색하고자 한다.

    Abstract PDF
    The purpose of this study is to assess the sustainability in 45 cities of all over Gyeongnam andGyeongbuk using weights and assessment system developed in leading research. The materialsof assessment used statistical data and spatial data were standardized for the systematic result.The assessment score was established using the normal distribution from 25 to 125 for removalof the very smallest and maximum value.According to the results, Tongyeong was assessed the highest by 82.5 score in environmentalsustainability index. In economical sustainability index, Pohang, Gumi, Changwon, Yangsanwere more than 79 score but Busan, Daegu, Andong were less than 70 score. Ulsan, Geoje,Yangsan were assessed higher in society-institutional sustainability index and Jinju,Munkyeong, Changnyeong were showed higher than other cities by more 79 score in quality oflife(QOL)’s sustainability index. In case of integrated sustainability index, Jinju that was thehighest sustainability in QOL was assessed by first city. However, Ulsan was assessed thelowest city among others. Therefore cities which have high sustainability will prepare a politicinvestment program for maintaining current conditions. Cities which have low sustainabilitywill grasp closely the environmental characteristics of urban and present the improvementdirection through monitoring continuously. Overall, these results can be used as tools to assessthe current cities and predict the future one. It is also necessary to establish a systematic urbanplanning for livable and sustainable city.

    Abstract PDF
    Air pollution and traffic noise from roads distributed near residential area has been a majorsocial problem. In this study, an environmental pollution map for a residential area of Shihung-city was made by an expectation model based on hourly traffic volume change. Using the resultfrom the model, a plan to reduce population in the residential area was established. The resultof the modelling is summarized as follows:1. At peak traffic hours (18 o’clock), 301-500 degree in hazardous and d25 degree (25% of theresidents are suffering extremely from the noise) in noise pollution were predicted inJeongwang Main Road in Shihung city.2. The calculated critical pollutant standard index, PSI showed the air pollution level,especially PM-10 high enough to require re-entrainment.3. It was expected air pollution would extensively extend over the area distribution of eachdegree. However, noise pollution problem was limited to the area near roads.

    ‘Probable Error’ as an EIA Method to Define Project Impact Area- Focusing on the Preparation of ‘Howitzer’ Fire Training Site -

    Jae Gu Kang , 최준규 , 조공장 and 2 other persons | 2007, 16(6) | pp.495~502 | number of Cited : 1
    Abstract PDF
    In Korea, military authorities have neglected to consider impacts of military projects on localcommunities and natural environment. Moreover, local communities have had difficulties indealing with the Ministry of National Defense (MND), which was stubborn enough not toimplement environmental assessment on their projects. In this situation, recent case, “EIA ofBaekgol Division’s Howitzer Fire Training Site” in the Supreme Courtin which judges upheldthe Higher Court’s decision that the division violated the Environmental Impact Assessmentlaw by ignoring to implement EIA reveals that military projects can no longer forgoenvironmental assessment. The decision has serious ramifications on the future ofEnvironmental Impact Assessment in military-led projects.This paper examines the proper scope of EIA in military-led projects and, more specifically,fire training site and searches for how to improve it through ‘probable error,’ a military trainingmethod that is applied to real ‘howitzer’ fire training. Probable error of the artillery field manualis nothing more than an error that exceeded as often as it is not exceeded and its scientificmethod was demonstrated through real fire tests in the US. Army. If it is applied to improveassessment methods about the proper scope of EIA in military ‘howitzer’ fire training site,‘probable error’ will improve effect prediction, mitigation and reliability.
