The air quality modeling was carried out to assess the impact of air quality for large scale urban development. The site for the assessment is Multi-fuctional Administrative City which locates in Yeongi-gun, Chungcheongnam-do and estimated population in 2030 is 500,000. Two automatic weather monitoring stations were installed to monitor the meteorological variables for a year and upper air meteorological parameters were measured using radiosonde for 5 days with 4 hours interval in every season. The air quality of standard air pollutants were also measured for 5 days continuously in every season. The results of wind field analysis based on the site measurements and CALMET modeling showed 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 and AERMOD are not appropriate and the unsteady-sate Lagrangian model such as CALPUFF is preferable. CALPUFF model was applied to assess air quality impact of new sources. The new sources were those for individual and group heating facilities as well as the traffic increases. The results showed that the estimated concentrations of CO and
pollutants by summing the impact concentration of new sources by the dispersion model and the ambient air concentrations by the site measurements were acceptable but those of PM-10 and
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.

To examine the sedimentary geochemical characteristics of sediment in the Tamjin River and Doam bay, the analysis was conducted, using the sample obtained in February 2000, on the grain size and the contents of metallic elements and organic carbon. The factors that influence the geochemical behavior of metallic elements in the surface sediment are grain size, organism, surrounding soil and
. To find out the pollution level of metallic elements, the enrichment factor (EF) and the index of geoaccumulation (
) were researched. The majority of metallic elements sustain their values in natural state. The elements such as K, Ba, Zr, etc. appear to be rich in some places. The EF and
of P, Cu, Zn, and Pb, which belong to toxic heavy metals, are partly related with man-made pollution. P and Cu have a high EF, Pb has a high
and Zn is high in both EF and
. The low contents of P and Cu are not likely to be related with the pollution of water environment. However, given the development of relative pollution, the research and the management regarding the pollutants are needed. Because Pb, naturally enriched by geological characteristics, has a large influence on water environment along with Zn, the adequate measures against man-made pollution should be worked out.

This study investigated the predicted and abserved outflow of groundwater which occurred during tunnel constructions. Among the 586 road construction projects from 1986 to 2006, 4 route 25 tunnel construction areas and 26 waste water treatment facilities under construction were studied. Most of the tunnel outflow prediction in EIA (Environmental Impact Assessment) process have been classified into the 17 types of units depending on the assessor's options, which have not conformed to the request of the residents and non government organizations. The investigation results showed that the outflow of underground water in tunnel construction areas averaged about
with the maximum
, and that the outflow mostly occurred in the early stage of tunnel excavation and diminished gradually. The prediction of outflow of underground water in the EIA process showed excessive results compared to observed outflow, the even 51.7 times. Consequently for more realistic prediction, current EIA method for prediction of outflow of underground water in tunnel construction areas has to adopt numerical methods coupled with hydraulics and geologic informations from unit methods of present time.

To investigate temporal and spatial variations of hydrodynamics and environmental conditions in Gyeonggi Bay, including Han River estuary, numerical experiments were performed using 3-dimensional fine grid numerical ocean model. The model successfully reproduced the physical phenomena already known in Gyeonggi Bay where tide and fresh water discharge are dominant forcings. The calculated harmonic constants of tide and tidal current agreed well with those of observations at nine tide stations and two tidal current stations. Tidal asymmetries along the Yeomha Waterway, mainly caused by non-linear effect, were well reproduced and agreed well with observations. Time series of salinity at four stations(A, B, C and D) and horizontal distributions of monthly averaged salinity show that Gyodong and Seokmo Waterways play an important role in fresh water discharge into the Gyeonggi Bay rather than Yeomha Waterway.

The purpose of this study is to assess the sustainability in 45 cities of all over Gyeongnam and Gyeongbuk using weights and assessment system developed in leading research. The materials of 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 removal of the very smallest and maximum value. According to the results, Tongyeong was assessed the highest by 82.5 score in environmental sustainability index. In economical sustainability index, Pohang, Gumi, Changwon, Yangsan were 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 of life(QOL)'s sustainability index. In case of integrated sustainability index, Jinju that was the highest sustainability in QOL was assessed by first city. However, Ulsan was assessed the lowest city among others. Therefore cities which have high sustainability will prepare a politic investment program for maintaining current conditions. Cities which have low sustainability will grasp closely the environmental characteristics of urban and present the improvement direction through monitoring continuously. Overall, these results can be used as tools to assess the current cities and predict the future one. It is also necessary to establish a systematic urban planning for livable and sustainable city.

Environmental Impact Assessment (EIA) is a kind of planning technique to seek ways to minimize environmental impact, a scheme to encourage sustainable development. With the launch of the Ministry of Environment in 1980, the EIA was introduced in Korea. Its full operation was initially driven by regulations on documenting EIA reports in 1981, which was piloted as a decision-making scheme where final decision were made at the development department after considering opinions suggested by the Ministry of Environment. At that time, dominance of the economic logic overwhelmed environ-friendly opinions, but thanks to the fourth revision of the Environmental Conservation Law in 1986, private projects came to be included on the EIA list. This was a turning point for the EIA to become a regulatory system. Local governments are also conducting the EIA regardless of the national-level EIA. In order to prevent and resolve increasingly severe environmental problems in Seoul in advance due to various construction projects, the Seoul Metropolitan Government, for the first time as a local government in Korea, legislated city decrees to introduce the EIA which has been underway from September 1, 2002. In particular, the Seoul government, unlike the Ministry of Environment, has included construction works on the list of evaluation projects, adopting the scoping and screen procedure scheme. In addition, complementing operational setbacks, the city government has revised and implemented decrees and enforcement laws on the Impact Assessment on Environment, Transportation and Disasters by shortening the consultation period, eliminating the submission of reports on construction, and expanding the waiver requirements in consultation over the reports. Therefore, development measures for the EIA scheme of the Seoul Metropolitan Government will be the target of the research. To that end, the up-to-date data of the Ministry of Environment, the Seoul government and local governments was collected, and latest materials from the EU, previous research and the Internet were gathered for analyses. By doing so, the flow of the EIA was reviewed, and the EIA schemes of local governments under the national EIA were analyzed. Furthermore, based on the Seoul government's recent data on the EIA based on the decrees, the background and legislation of the Seoul government's EIA were analyzed along with the developments for the environmental organizations. Setbacks were derived from the implementation period, evaluation procedures, consultation period and details of the EIA, and corresponding development measures were proposed.

Air pollution and traffic noise from roads distributed near residential area has been a major social 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 result from the model, a plan to reduce population in the residential area was established. The result of the modelling is summarized as follows: 1. At peak traffic hours (18 o'clock), 301-500 degree in hazardous and
degree (25% of the residents are suffering extremely from the noise) in noise pollution were predicted in Jeongwang 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 each degree. However, noise pollution problem was limited to the area near roads.

In Korea, military authorities have neglected to consider impacts of military projects on local communities and natural environment. Moreover, local communities have had difficulties in dealing with the Ministry of National Defense (MND), which was stubborn enough not to implement environmental assessment on their projects. In this situation, recent case, "EIA of Baekgol Division's Howitzer Fire Training Site" in the Supreme Court-in which judges upheld the Higher Court's decision that the division violated the Environmental Impact Assessment law by ignoring to implement EIA-reveals that military projects can no longer forgo environmental assessment. The decision has serious ramifications on the future of Environmental 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 training method that is applied to real 'howitzer' fire training. Probable error of the artillery field manual is nothing more than an error that exceeded as often as it is not exceeded and its scientific method was demonstrated through real fire tests in the US. Army. If it is applied to improve assessment methods about the proper scope of EIA in military 'howitzer' fire training site, 'probable error' will improve effect prediction, mitigation and reliability.

Since 1990s many skyscrapers have been built in Seoul. However, gusty winds occur among tall buildings by descending turbulences due to the upper air blocking. This study aims to investigate the wind characteristics of skyscraper prevailing wind direction. In order to evaluate the building wind in this area, The wind speed and the wind direction were measured using propeller type RM-Young wind monitor in this study. The maximum wind speed was recorded by 15.1 m/sec and the main wind direction is WNW and NW. The ultimate purpose of this study is to figure out the phenomena of building wind impact and also to provide essential basic data for establishing proper guidelines in building wind impact assessment for skyscrapers in Korea.

Korea has 30 years of experiences in environmental impact assessment (EIA). Although EIA includes sanitation-public health factor, considering health impacts, among 74 unit projects of 17 sections, health impacts haven't been properly considered or have been ignored in many cases. The increasing awareness on the importance of health impacts has triggered this study to seek an optimal introduction scheme of health impact assessment (HIA). The processes of EIA already include screening, scoping, analysis, impact assessment, consultation, document review, decision making and monitoring, in which they would be the essential parts of HIA. In this context, integrating HIA into the existing EIA process could be the most effective way to use the benefits in both legal and procedural processes existed and to avoid the confusion and overlapping since the close relationships between environment and health impacts might be. Furthermore, it is desirable that the existing sanitation-public health factor should be substituted by and extended to environment-health factor with sufficient determinants to properly consider health impacts. When considering the first step of HIA, the prospective and qualitative approach is suitable more than the retrospective and quantitative one due to the lack of database accumulated. Similarly, an approach based on epidemiology and toxicology could analyze the limited evidences and impacts related to human disease, whereas one based on socio-science and psychology could provide the effective means available for predicting how the people and community will act by the change of surroundings. Checklist approach with various and comprehensive health determinants focused on prospective and qualitative methods will be very useful for more convenient and progressive dissemination of HIA. Various checklist approaches of toolkits could be found from HIA documents elsewhere, for example Westminster Toolkit, and they would be helpful to figure out how to develop common procedures and health determinants for checklist, in which the unique characteristics on korean cultural and political context compared to abroad should be carefully considered since checklist would be the most basic and essential part of HIA. After the establishment of checklist and procedural processes, the pilot projects should be conducted. Main purpose of pilot projects is to apparently prove the effectiveness and profitability of HIA. Pilot projects should be implemented to decide the effectiveness and suitability of HIA for future projects, programs and policies, and should be provided as the positive cases that can be achieved through the proper implementation and progress.

In order to establish and implement the total maximum daily load (TMDL) management plan in Korea, it is necessary to set the source units and calculate discharge loads for non-point source pollutants such as BOD, COD, SS, TN and TP. This study analysed the corelation between stormwater runoff characteristics and event mean concentrations (EMCs) of non-point source pollutants. As the result of the corelation analysis, we knew that all the antecedent dry days (ADD) and the rainfall correlated lowly with non-point source pollutants in the urban areas such as resident area, industrial area, business area, road area and parking area. Therefore, it is necessary to get all samples from stormwater starting point to stormwater ending point and standardize the sampling method of stormwater in order to obtain more accurate EMCs for landuse.
