    Abstract PDF
    Non-point pollution is caused by many diffusive sources, unlike a point pollution derivedfrom industrial wastewater treatment plants or sewage treatment plants. Runoff of non-pointpollutants is originated from rainfall or thawing in short period of time moving over andthrough the a ground surface. They cause ill effect on the quality of neighboring aquaticenvironment. To prevent effectively the wash off from non-point pollutant, it should beimmediately reduced at the source or be treated after gathering of runoff water. This study hasbeen carried out for the best width of riparian buffer zone. So we implemented the experimentin terms of its depth, width and kind of vegetations and calculated the reduction of pollutantsloading. The experimental zone encompasses the watershed of Namhan River (KyunggidoYangpyunggun Byungsanri). The region was divided into 5 land cover sectors : grass, reed,pussy willow, mixed(grass+pussy willow) and natural zone to compare effectiveness ofvegetation. Water samples from four points have been collected in different depths. And thepollutant removal efficiency by sectors with different plant species was yielded throughinfluent with one of each sample. And we obtained the correlation between the width ofriparian buffer zone and the removal efficiency of pollutants. Using correlation result, the widthof riparian buffer zones which needs to improve the water quality of river could be derived.

    Abstract PDF
    The Korea Environmental Impact Assessment (EIA) system was introduced in 1977 throughthe Environmental Conservation Act. It has progressed through many laws and regulationspromoting the balance between development and conservation, and functioning as aPreventitive environmental policy. Despite the efforts to minimize environmental damage fromdevelopment and to uplift social awareness of environmental preservation, deficientimpartiality and objectivity in completing and investigating environmental assessments, therehave continously existed conflicts among related stakeholder, neglecting arrangements andineffectiveness of public participation. This research present EIA obstacles and analyzes theoverall status of the EIA through surveys from related experts. On the basis of this research, theactual complications regarding the developer, public participation, examiner and consultant arebrought about. Also, remedies are proposed to ensure effective EIAs and restore confidence in them.

    Ecological Restoration and Environmental Impact Assessment for the Realization of the Central Theme, Preservation, Suggested in the National Anthem of Korea

    KIM, Eun Shik , HONG SUNKEE | 2008, 17(1) | pp.25~45 | number of Cited : 3
    Abstract PDF
    This review was made to discuss the issues of ecological restoration and environmentalimpact assessment (EIA) related to the preservation of natural environment, the central themeexpressed in the National Anthem of Korea. The authors notice that the key word or the centralphilosophy contained in the verses of the National Anthem of Korea is the preservation ofnational land and eternal identity for future generations, which is thought to be pursued throughthe attainment of ecological sustainability. A conceptual model for the sustainable managementof natural ecosystems was suggested for the efficient utilization and the preservation of them,whose activities should be promoted by those of conservation and restoration instead ofdestructive development and negligence, respectively. Here, the preservation of naturalenvironment can be directly pursued through the restoration of degraded ecosystems andlandscapes and the utilization of natural environment can be directly pursued through theconservation of natural resources and wise management of natural ecosystems and landscapes.After reviewing the major characteristics and activities of the restoration of degraded ecosystemsand landscapes, discussion was further extended to points for the promotion of the EIAactivities. To point out some of them, it is needed for the public to better understand the natureof sustainable management of natural environment, for the society to put extensive energy andresources in the restoration of degraded ecosystems and landscapes, and for the government to install higher levels of ministries than that of the Ministry of Environment in dealing with the issues related to the ‘preservation’ of national land, people, culture and the security of the sustainability for future generations, where EIA and strategic environment assessment (SEA) can directly contribute to the sustainability of the country and future generations.

    Assesment of Water Quality Standards using Stochastic DistributionCharacteristics between Dynamic Modeling Results and Observed Data

    Ha, Sungryong , Jiheon Lee , 서세덕 and 2 other persons | 2008, 17(1) | pp.47~56 | number of Cited : 3
    Abstract PDF
    Total Maximum Daily Load(TMDL) is a core basin management system to assign totalemissions of pollutants to unit basin and emission source within a limit of the target waterquality and to secure sustainability. considering “Environment and development” together. Bycurrent technical guidance of TMDL, the water quality in the riverbed of which the target waterquality is noticed, must achieve the target; and the water quality standard for evaluatingachievement of the target should be prescribed as non-excessive probability quality of water onthe basis of the pertinent water quality documents. Therefore, the study calculated the targetwater quality by each unit basin which the target water quality must be noticed through theanalysis of probability for water quality documents in rivers at the time of establishing a plan,and the study evaluated the achievement possibility of the target water quality by analyzingand comparing the target water quality plan with the standard water quality to evaluate theachievement of the target water quality.As the result, applying the proposed method to Mihocheon River system, it is concluded thatselected the target water quality (Each BOD 3.3mg/1 and BOD 3.0mg/1) in Miho A and MusimA is available. Of course, it showed that the target water quality: BOD 2.5mg/1 in Miho A andBOD 3.0mg/1 in Musim A, could be achieved if the small reduction in B unit area wasimplemented.
