  • This study was intended to estimate the soil runoff at the basin of Mandaechun where the measure needs to be taken to deal with the increasing muddy water resulting from soil runoff during wet season and torrential rain at the high reaches of the Soyang lake where highland vegetables are cultivated and soil replacement for improvement is carried out every two to three years. The study was carried out in such a way of identifying the topographic factors using geographical spatial data from Water Management Information System (WAMIS) and ARC-VIEW program and estimating the soil runoff by rainfall frequency using Revised Universal Soil Loss Equation (RUSLE), and furthermore, evaluating the soil runoff contribution at the basin of Mandaechun based on estimate of the soil runoff by section.

  • In this research, we have selected the region of Jawoon river that is the area of high land vegetable growing in the upper Soyang Reservoir and we have observed actual floating materials that generate negative nutrition and turbidity of the Reservoir water and the changes of water quality by raining of each month for one year of 2005 in order to monitor the relationship of pollution sources by the outflow of rain water. In addition, we also have conducted statistical inspection methods such as correlation analysis and regression analysis on strength of raining force and rain continuance time among the elements affecting the outflow of floating materials.

  • In the literatual studies on the pruritic dermatoses, the results were as follows. 1. In Oriental medicine, Pruritic dermatoses is belong to the cartegory of the 'Pung- soyang(風瘙痒)', 'Pungyang(風痒)', 'Yangpung(痒風)', 'Sinyang(身痒)' etc. 2. Pruritic dermatoses is occurring idiopathically without primary lesion, marked by intense itching. 3. The pathogenic factors of Pruritic dermatoses is divided two parts. One is exo- genous pathogenic factors which including the wind-cold and wind-heat The other is endogenous pathogenic factors which including the blood-deficiency, the blood-heat, the wetness-heat of liver & gallbladder, the spleen-asthenia and impairment of the liver & kidney etc. 4. In the prescription of Pruritic dermatoses, it was used Gyejimahwanggakbantang(桂枝麻黃各半湯) in exogenous pathogenic factors, was used Danggyiyumja(當歸飮子), Sopungsan(消風散), Bangpungtongsungsan(防風通聖散), Yanghyulyunbuyum(養血潤膚飮) etc.

  • A real-time single reservoir operation model using the Min-max Dynamic Programming for the flood control of Soyanggang Dam and Choongju Dam is developed. The objective function is to minimize the maximum release from each dam and the constraints are those from ther reservoir and channel characteristics. Control and utilization efficiencies are used to measure the performance of the reservoir operation method (ROM). In comparison with those of simulation models(such as the Rigid ROM, the Technical ROM and the Linear Decision Rule), the efficiencies of the optimization model are superior for all return periods.

  • 최근 많은 수문학자들은 전지구적 기후변화로 인한 피해 예방과 저감을 위해 기후변화가 수문학적으로 어떤 영향을 미치고 있는지 알기 위해 많은 연구를 진행하고 있으며, 기후변화시나리오를 작성하고자 이산화탄소 배출농도를 가정하여 다양한 시나리오를 생성하고 있다. 본 연구에서는 효율적인 수자원 관리를 위해 저해상도의 GCM(General Circulation Models) 모형에서 생성되는 모의결과를 유역 규모의 단위로 스케일 상세화 기법(downscaling)을 적용 시켜 보고자 한다. 이를 위해 2007년 IPCC AR4와 함께 제시된 SRES A1B 시나리오를 채택하여 우리나라 기상청이 연구에 참여 제공하고 있는 EHCO-G 모델의 모의결과를 이용하여 소양강 유역에 적용하였다. 상세화 기법으로는 현재와 과거의 입력값들과 이에 대응된 출력값들을 알고 있는 경우에 미래의 새로운 입력값들에 대한 예측값들을 추출하는데 유용하며, 비선형적 비연속적인 특성이 강한 모델에 강점을 가지고 있는 인공신경망(Artificial Neural Network) 모델을 사용하고자 한다.

  • 과거에는 홍수조절의 관점에서 하도 내 식생은 통수단면적의 축소와 조도상승 등의 문제로 기피의 대상이 되어왔으나 최근 저수지자연하천의 생태계 보전 복원을 통한 하천 환경의 개선, 경제 성장 및 생활환경의 질적 향상에 의한 하천변 경관조성과 휴식처 조성 등 사회적 요구가 증대하여 하도내 식생의 영향을 고려한 하천관리의 중요성이 더욱 강조되고 있다. 본 연구에서는 소양강댐 직하류 하천을 대상으로 홍수기 방류시 식생에 의한 수위변동을 모의함으로써 대상하천의 통수능 검토를 실시하였다. 이를 위하여 대상유역의 식생분포를 현장조사를 통해 파악하였고 단면별 수위상승을 모의하기 위하여 1차원 및 2차원 수리학적 수치모형을 활용하여 식생을 고려한 흐름 해석을 실시하였다.

  • The neural network is a mathematical model of theorized brain activity which attempts to exploit the parallel local processing and distributed storage properties. The neural metwork is a good model to be applied for the classification problem, large combinatorial optimization and nonlinear mapping. A multi-layer neural network is constructed to predict rainfall. The network learns continuourvalued input and output data. Application of neural network to 1-hour real data in Seoul metropolitan area and the Soyang River basin shows slightly good predictions. Therefore, when good data is available, the neural network is expected to predict the complicated rainfall successfully.

  • This study tries to identify distributional characteristics of stream incision rates at 23 points in the northern part of the Taebaek Mountains. Soyang-gang, Naerin-cheon, Odae-cheon, Dong-gang and upper reaches of Okdong-cheon Rivers closed to the Range show higher incision rates and the rates clearly decrease with distance from the Range. Therefore, the incision process in the northern part of the Range has been greatly influenced by uplift around the Range, and the Sobaek Mountain Range seem to play a role in the incision process. Limestone areas show lower incision rates due to degradation of terrace surface by dissolution. This study suggests that local hydrological, geological and geomorphological conditions can be regarded as an important factor in stream incision rates, although stream incision rates are greatly influenced by regional uplift.
