  • This study synthesizes previous research accomplishments with analysis of problems and counterplan for the riparian forest zone management and ongoing research strategy is suggested. If a part of budgets for water use allotments is supported for forest watershed owner, this policy for the forest owner could encourage the forest management of watershed. Integrated riparian forest management guideline in city and county needs to be established for the implementation of government guidelines. Base on the guideline, working plans of city and county could be evaluated. Public Forest Tending Work for stream water quality and quantity conservation should be enlarged for forest watershed and forest area management in five big river watersheds. Forest watershed should be managed with a connected system for a pollutant reduction strategy in urban and industrial areas.

  • 건설사업은 인간의 생활의 질을 높이고 편리한 인간생활을 위해서 필수불가결한 요소이지만 이러한 건설행위자체는 개발과정에서 환경오염에 커다란 영향을 미친다. 또한, 쾌적한 환경에 대한 욕구 증대로 사업수행시 대기관련민원의 증가로 인한 공사지연이 빈번히 발생하고 있어 건설사업에서의 대기환경관리 중요성이 크게 부각되고 있다. 이에 본 연구에서는 건설사업시 환경관리를 위한 관리지침개발을 위해 건설사업 추진시 발생하는 여러 가지 오염 중 대기오염에 대한 관계법령 및 규제사항 검토, 환경관리 주요검토항목 및 주요관리지침을 도출하는 과정을 통해 건설사업 단계별 행동관리지침을 개발하여 건설사업의 환경관리 체계를 구축하는 것을 목적으로 한다.

  • This study aims at establishing master plan for efficient establishment of comprehensive drought management information system as non-structural drought counterplan which provides drought damage in advance. Domestic and abroad research related to drought were surveyed and analyzed through many literature and internet for systematic drought management information system. Long-term master plan for comprehensive drought management information system is divided into 3 steps. In first step, drought monitoring system including development of hydrological drought assessment index, drought outlook analysis method and GIS web based drought monitering system is established. In second step, water supply plan and guideline through water shortage danger assessment by areal characteristics is established. In third step, comprehensive management information system through export system linked to KORSIM and establishment of information shared system between each bureau related to drought. Based on this study, master plan for efficient development and application of drought management information system is proposed, it is expected to be applied as guideline for second and third step of drought management information system.

  • According to the technical guideline of water pollutant load management, the rainfall captured ratio which can be estimated by the empirical formula is an important element to estimate reduction loads of non-point pollutants water quality control basin. In this study, the rainfall captured ratio is altered to stormwater captured ratio considering its meaning in the technical guideline of water pollutant load management, and the new empircal formula of stormwater captured ratio is suggested. In order to do this, we calculate stormwater captured ratio by using the hourly rainfall data of seven urban weather stations (Busan, Daegu, Daejeon, Gangreung, Seoul, Gwangju, and Jeju) for 43 years. The regression coefficients of the existed empirical formula cannot reflect the catchment properties at all, because they are fixed values regardless of regions. However the empirical formula of stormwater captured ratio has flexible regression coefficients by runoff coefficient(C), so it is allowed to consider the characteristics of runoff in catchment. It is expected that reduction loads of storage based water quality control basin can be more reasonably estimated than before.

  • Korean water quality guidelines for agricultural were derived to protect agricultural water uses according to the Canadian methodology. The adverse effect of heavy metals in agricultural water was of concern due to its persistence, bioaccumulation and ecotoxicity to crop plants. The ecotoxicity data of cadmium, copper, lead, and zinc were collected for the crops grown in Korea, and used to estimate the species maximum acceptable toxicant concentration (SMATC), which corresponds to the water quality guideline. Values of irrigation per year and soil bulk density were revised to reflect the Korean situation. The estimated guideline values for cadmium, copper, lead, and zinc were 0.01, 0.5, 0.1, and 1.0 mg/L, respectively. These values are in agreement with the agricultural water quality guidelines of foreign countries and current Korean water quality standard for the protection of public health. Current water quality standards in agricultural uses were for management of public water resource, and was not prepared to protect crop plants from contaminants. The results of this study will be a basis for the designation of Korean water quality guidelines for the protection of agricultural water uses in the future.

  • This technical report was developed to suggest the guideline to assess the safe use and handling metalworking fluids (MWFs) in machining operation. The basis of this method developed in this study was based on self assessment procedure recommended by Organization Resources Counselors (ORC) of the United States (US). In addition, various MWF management elements obtained from the review on various articles, reports and author's experience regarding MWF were newly added to the evaluation guideline. A total of four areas were finally selected in order to control exposure to MWF used in machining operations. They are all related to the presence and efficiency of the control measures, exposure assessment, management on tank and sump, and safe treatment of chips and metal fines generated during machining operations. Each area is consisted of several related elements. Several evaluation areas and elements used in this study could be revised, replaced, added and deleted according to the process environment, evaluation objectives and evaluator's (manager) criteria etc. This evaluation guide manual could be used for safe management of MWF in metalworking operation. In addition, industrial hygienists can use this evaluation method for auditing and evaluating the management status on MWF.

  • Proper management of small rural watershed is important since it does affect water quality improvement of larger scale watershed. Therefore, effective small watershed management guideline including participatory program of local people is required to achieve water environment improvement. Feasibility of water quality goal, short and long-term watershed management plan and funding sources were investigated by field monitoring of Hampyungchun watershed which has characteristics of rural stream, and literature review. The relevant parties and their roles fer watershed management were identified and suggested. A hybrid model, that is mixture of government driven model and NGO model, is recommended for watershed management organization in this study.

  • The guideline of selection of Integrated Management Practices (IMPs), such as wood, green roof, lawn, and porous pavement, for Low Impact Development (LID) design was proposed by ranking the reduction rate of surface runoff using LIDMOD1.0. Based on the guideline, LID was designed with several scenarios at two apartment complexes located at Songpa-gu, Seoul, Korea, and the effect of LID on surface runoff was evaluated during last 10 years. The effect of runoff reduction of IMP by land use change was highly dependent on the kind of hydrologic soil group. The wood planting is the best IMPs for reduction of surfac runoff for all hydrologic soil groups. Lawn planting is an excellent IMP for hydrologic soil group A, but reduction rate is low where soil doesn't effectively drains precipitation. The green roof shows constant reduction rate of surface runoff because it is not influenced by hydrologic soil group. Compared to the rate of other IMPs, the green roof is less effect the surface runoff reduction for hydrologic soil group A and is more effect for hydrologic soil group C and D followed to planing wood. The porous pavement for the impervious area is IMPs which is last selected for LID design because of the lowest reduction rate for all hydrologic soil group. As a result of LID application at study areas, we could conclude that the first step of the strategy of LID design at apartment complex is precuring pervious land as many area as possible, second step is selecting the kind of plant as more interception and evapotranspiration as possible, last step is replacing impervious land with porous pavement.
