The purpose of this study is to analyze soil erosion quantity of a basin by using DEM, soil map and landuse map, and to find a soil erosion hazard zone in a basin. In this study, RUSLE was used to analyze soil loss quantity of Gwanchon subbasin, which is the subbasin Seumjin river basin, was chosen as a research area. This study used a maximum daily precipitation during 40 years of Gwanchon Observation, and DEM of US DMA and the soil map of the Institute fo Agricultural Science were used as the data concerned with topographical charateristics. The subject map was drawn to analyze soil erosion hazard zone by using the above data and maps. According to the results of the analysis, a lot of soil loss shows in a farmland area. The analysis of the above gave the result that from 0.65% to 33.5% of farmland area was found to have a higher chance of soil erosion for each frequency.

Sediment yield and sediment transport in a basin bring about decrease of conveyance by the change of bed section, and have an influence on an aggravation of water quality and freshwater ecosystem. This study is to analyze the characteristics of outflow sediment according to land-use in Mushim-cheon flowing through forest area, farmland area and urban area. The upper stream of Mushim-cheon consists of forest area and farmland area. The suspended sediment is observed through 10 rainfall events in 5 sites. As a result of analyzing characteristics of landuse, the site of Bangse-gyo takes up 69% of Mushim-cheon, and farmland area(27.1%) and forest area(63.7%) take up 90.8% in Bangse-gyo. Accordingly, these two areas have the high possibility to occur sediment. The suspended sediment of this site shows the highest concentration. Transferring to the downstream and the urban, the concentration of suspended sediment gets decreased. The suspended sediment occurred in the upper stream of Mushim-cheon prior to Bangse-gyo has an influence on the downstream, and has a slight influence on the urban area.

The dose-response effect of polysaccharide extracts(PS-1) from Artemisia iwayomogi was investigated under various hepatic disease models. Silymarin, DDB and UDCA were used as reference compounds. We found that the maximal effective dose of PS-1 was 100 ㎎/㎏ b.wt. in CCl_4-induced hepatotoxicity, D-galactosamine-induced hepatitis, in ANIT-induced cholestasis and 300 ㎎/㎏ b.wt. in CCl_4-induced chronic liver disease, 30 ㎎/㎏ b.wt. in chronic bile duct ligation and chronic ethanol fatty liver. These findings suggest that PS-1 fraction protects the hepatocyte against various hepatic injuries, and this fracton might be of therapeutic value.

본 연구의 목적은 대청댐 다목적 저수지의 홍수조절능력을 극대화하기 위한 홍수시 실시간 저수지운영 의사결정 지원 시스템을 개발하는 것이다. 시스템 개발을 위해 시스템의 분석과 설계, 프로토타입의 구축, 가상적인 실시간 적용과 검증을 실시하였으며, 연구를 통해 발견된 각종 문제점을 개선하여 장차 실시스템의 구축을 완료하고, 홍수기간 중 기존의 한국수자원공사 방재시스템과의 동시 운영시험을 통해 시스템의 적용성을 검증하여 실용화를 추진하고자 한다. 본 연구를 통해 설계, 원형의 개발이 완료된 의사결정 지원시스템은 데이터베이스와 모델베이스, 사용자 인터페이스 및 그래픽 디스플레이 시스템으로 구성되었으며, 개발된 시스템의 적용성을 검증하기 위하여 1987년 7월 및 1995년 8월의 홍수 사상에 대해 본 시스템을 가상 실시간으로 적용하여 의사결정과정을 수행하고 실제 운영 결과와 비교·검토하는 오프라인 분석을 실시한 결과 시스템을 이용한 실시간 저수지 운영을 통해 대청댐의 홍수조절 능력을 향상시킬 수 있을 것으로 판단되었다. This paper describes the results of the project to develop a decision support system for the Daechung dam in the real time reservoir operation that aims to maximize the flood control effect for the downstream Geum river. The project was planned to carry out the following tasks as 1) systems analysis and design, 2) development of a prototype system, and 3) verification of the system. In the decision support system, a modelbase and a database are included along with the graphical user interface that is able to visualize the results of model run and hydrologic status. The system was verified through the pseudo real time applications to the historical flood events those occured in July, 1987 and August, 1995. Decision making processes were carried out using the developed system and the results were compared with the real operations at the time. Through the verification study of the developed system, It was conceived that the newly developed system can fast up the reasonable decision making for the flood control at the downstream Geum river and the system could be actually practiced with some more efforts to improve the performance of the system.

본 논문은 공간의사결정지원시스템의 시범시스템으로서, 다목적 저수지군의 실시간 통합유역홍수조절 시스템에 대한 연구이다. 본 공간의사결정지원시스템은 자료관리시스템, 실시간 기상 및 수문자료 모니터링시스템, 저수지군의 모의 및 최적화를 모형기반시스템, 시스템의 효율적인 사용을 위한 사용자편의시스템으로 구성되어 있다. 홍수사상 동안에 수시로 갱신되는 홍수 수문자료의 공간적인 분포를 예측하여 제공하기 위하며, 신경망 알고리즘이 사용되었다. 예측자료는 유역 저수지군의 게이트조절을 위한 최적화 전략수립을 위한 입력자료로서 활용된다. 본 시스템은 1995년 한강유역의 홍수사상에 적용되었으며, 하류의 홍수피해를 최소화하면서 홍수기 이후의 수자원확보를 최대화할 수 있는 운영률을 제시하였다. A prototype spatial decision support system (SDSS) is presented for integrated, real-time river basin food control in a multipurpose, multireservoir system. The SDSS integrates a GIS with a database management subsystem, a real-time meteorological and hydrological data monitoring system, a model-base subsystem for system simulation and optimization, and a graphical dialog interface allowing effective use by system operators. The model-base subsystem employs an artificial neural network in a real-time flood forecasting module providing spatially distributed forecasted flows that are updated as the flood event progresses. Forecasted, basin-wide discharges are input into a dynamic programming module providing optimal gate control strategies, which are also updated in real-time. The SDSS for flood control is applied to the Han River Basin in Korea and demonstrated through simulated application to a severe 1995 flood event. Results of the case study indicate that integrated operational strategies generated by the SDSS for flood control substantially reduce downstream flood impacts, while maintaining sufficient conservation storage for water use subsequent to the flood seas.

Shim, Soon-Bo,Lee, Yo-Sang,Koh, Deuk-Koo Korea Water Resources Association 1999 Korean journal of hydrosciences Vol.10 No.-

An integrated system of GIS and water quality model was suggested including the pollutant loads from the watershed. The developed system consits of two parts. First part is the information on landuse and several surface factors concerning the overland flow processes of water and pollutants. Second part is the modeling modules which include storm event pollutant load model(SEPLM), non-storm event pollutant load model(NSPLM), and river water quality simulation model(RWQSM). Models can calculate the pollutant load from the study area. The databases and models are linked through the interface modules resided in the overall system, which incorporate the graphical display modules and the operating scheme for the optimal use of the system. The developed system was applied to the Chungju multi-purpose reservoir to estimate the pollutant load during the four selected rainfall events between 1991 and 1993, based upon monthly basis and seasonal basis in drought flow, low flow, normal flow and wet flow.

A SYSTEM DEVELOPMENT FOR ESTIMATING NON-POINT SOURCES POLLUTANT LOADS FROM WATERSHEDS USING GIS

Shim, Soon-Bo,Kim, Joo-Hun,Koh, Deuk-Koo Korea Water Resources Association 2000 Water engineering research Vol.1 No.3

The purpose of this study is the development of a system for estimating non-point sources pollutant loads from a watershed, which enables users to get insights of pollutant load distribution in the watershed during rain as well. Based on the Geographic Information System, this non-point source pollutant loading estimation system(NSPLES) consists of three distinct models such as a distributed rainfall-runoff model, a soil loss and delivery model, and a non-point source pollutant model. It also includes GIS modules for preprocessing the input data for the models and graphical postprocessing of the model outputs. The system output aren't only the hydrograph, sedimentograph, and pollutograph at the watershed outlet, but also various maps that show the distribution of soil loss over the watershed. The developed system was applied to the two upper stream areas of Sumjin river basin, Ssangchi and Gwanchon basins, and three rainfall events for respective subbasins during 1992 and 1998 were selected for the system application. The results of this showed relatively higher corelation between observed data and simulated data, and proved the applicability of the system.
