Cheongpungho number is located in the center of South Korea Jecheon Peninsula, Chungju cheongpungho be formed by hydroelectric dam construction in 1984, now has been changed to a large man-made freshwater sites during the past 30 years. Recent Jecheon government is developing natural healing resort and entertainment performances for the future, in comparison to the feasibility study of the region using remote sensing technology and site planning was conducted in geographic research and analysis, and as a result, we have a very effective to incorporate the color maps using aerial photography and digital terrain analysis and usage analysis to prove and was in the riverside area for the future of the business and the research proposal facilities and events of the brand, to be more multi-cultural festival form apply new high-tech fusion experiments suggest new direction for future tourism.

Cheongpungho and riversides are located in the center of South Korea Jecheon Peninsula, cheongpungho be formed by a chungju hydroelectric dam built in 1984 has now been changed as a freshwater lake created by the center of the South Han River upstream over the past 30 years. Recent Jecheon-sigovernment is developing the entertainment and natural healing resorts for the future, this research is using remote sensing techniques and field survey plan in comparison to the feasibility study of the cultural festival of the area was conducted in geographic research and analysis very effective to conduct the natural environment and terrain analysis by aerial photography and remote sensing techniques that can be proven integration and cultural content, in the riverside area of future business creation and tourism resources of the facilities and events in the new brand through research It was envisioned. As a result, we propose a new direction for the future of cultural tourism to participate in the new state-of-the-art digital imaging technology to traditional cultural content in fusion experiments to be more multi-cultural festival is formed.

In this study we investigated the effect of a floating photovoltaic (FPV) system in Cheongpung Lake on water quality. The FPV with a tilt angle of 33° covered ca. 0.04% of surface area (97 ㎢) of Chungju Lake. The water qualities of the whole lake before and after installation of FPV were first compared. DO, BOD, TOC, and Chl-a of the whole lake were increased, while conductivity decreased after installation period at the significance level of 0.05. This change was probably due to the increased influx of nutrients by 40% resulting from increased precipitation during the same period. We also measured water quality parameters on May and Nov. 2017 at the FPV center (FPVC) and nearby control sites, and compared water quality. The result showed that the FPVC and nearby sites were not significantly different (p>0.05), demonstrating that the FPV does not cause a decline of water quality. The water temperature, light intensity, and phytoplankton community were also measured. The water temperature was not different between the sites, while the light intensity decreased to 27~50%. Despite reduced light intensity at FPVC, the phytoplankton standing crops and the number of species were not significantly different (p>0.05). However, in the early November samples, standing crops was significantly higher in FPVC than control with periphytic diatoms belonging to Aulacoseira genus being dominant. This may be due to the temporal water body behavior or local retention of current by FPV system. This study may provide a measure of future installation of a FPV system.

It's a very meaningful experimental study to image restoration of ancient villages vanished at the real life spatial world. Focused on Cheung-Pyung Lake around where most part were flooded by the Chung-Ju large dam founded in early 1980s, we used remote sensing technique in this study in order to restore topographical features before the flood with 3 dimensional effects. It was gathered comparatively good satellite photos and remotely sensed digital images, then its made a new color image from these and the topographical map which had been made before filled water. This task was putting together two kinds of different timed images. And then, we generated DEM(digital elevation model) including the outskirts of that area as harmonizing current contour lines with the map. That could be a perfect 3D image of Cheung-Pyung around before when it had been flood by making perspective images from all directions, north, south, east and west, for showing there in three dimensions. Also, flying simulation we made for close visiting can bring us to experience their real space at that time.

제천, 충주, 단양의 3 개 지자체에 걸쳐 있는 충주호는 매년 여름철 집중호우시 부유쓰레기가 $3,000\~45,000\;m^3$ 의 범위에서 반복하여 발생하고 있으며 이들 대부분은 제천시 관내에서 수거되고 있다. 현재 부유쓰레기의 수거 및 육상 집하는 수자원공사가 담당하고 있으며 제천시는 이를 폐기물 매립장으로 운반하여 매립하고 있다. 이러한 부유쓰레기는 무게로는 그리 많지 않으나 부피가 매우 커 운반시 수거 차량의 운행대수가 많아지고 매립지 용량을 크게 소모하는 등 쓰레기 처리과정상의 문제점을 발생시키고 있으며 특히 부유쓰레기의 발생은 1 회성이 아니라 매년 장마와 홍수가 발생하면 되풀이되는 현상으로, 수자원 확보 및 홍수조절을 위해 설치된 댐에 의해 집중호우시 발생된 부유쓰레기가 댐 수위가 낮아짐에 따라 댐 주변부에 잔류하게 되어 수자원 및 수질 관리에 큰 어려움을 발생시키고 있다. 이러한 부유쓰레기는 댐 상류지역에 방치된 쓰레기들이 강우시 지표류와 함께 떠내려 온 것들로서 발생원인의 완전 제거는 불가능한 실정이므로 발생된 부유쓰레기를 최대한 신속히 수거하고 수거된 쓰레기는 소각이나 톱밥 생산 등의 물질자원화 방법으로 매립 양을 최소화 할 필요가 있다. 이에 본 연구에서는 충주댐에서 매년 집중호수시 발생하는 부유쓰레기의 발생 및 수거, 처리실태를 조사하며 또한 제천관내에 부유 쓰레기의 집중되는 원인을 분석하고 이로부터 적절한 부유쓰레기 관리대책을 수립하고자 하였다. 충주댐 부유물 발생 현황 조사 및 처리대책에 관한 연구결과는 다음과 같다. 부유쓰레기 발생량은 태풍의 발생에 따라 급격히 증가하여 년간 $12,587m^3\~45,356m^3$ 이 발생하고 있었다. 댐 및 하천 흐름 해석을 위해 2 차원 동수역학 모델인 RMA2 모형을 이용하여 충주댐에서의 물의 흐름을 해석한 결과 옥순대교$\~$청풍대교 구간 사이에 댐 및 지형적 영향으로 인해 잘 발달된 와류가 하도 전체를 통하여 발생되고 있었고 이는 댐 부유물 정체현상이 나타나는 지점과 잘 일치하고 있었다.
