도암댐 조사 및 수질오염상대 분석에 대한 관한 연구 = Survey of Doam Dam and Study on Water Pollution Analysis

다국어 초록 (Multilingual Abstract)

This study is to analyze and check the water quality of Doam Dam by measuring the water quality of Doam Dam and Gangneung Namdaecheon Stream as a research project on water pollution in Doam Dam.
The complaints began in 1991 with water pollution in the Gangneung City Council and continued to work to solve the problem for a long time, but after the verification of the water quality of the water quality improvement facility in 2012, consultations on the development door have been cut off.
Due to the drought, there is a need for measures to analyze the condition and analysis of water pollution to maintain the ecosystem of the river overcoming the drought, considering the changes in conditions as there is a baby to use Doam Dam water.
The scope of the study includes Songcheon tributaries Chahangcheon, Daegwallyeongcheon, and Yongpyeoncheon, and the water quality measurement area is located in the Songcheon area and the Namdaecheon area in Do-reum, Gangneung, and Namdaecheon area.

국문 초록 (Abstract)

본 연구는 도암댐에 수질오염에 대한 연구용역 과제로서 도암댐 및 강릉남대천의 수질상태 측정을 실시하여 도암댐의 수질의 상태를 분석하고 확인하여 현상태의 도암댐의상태를 알수 있기위한 연구이다.
민원으로는 1991년 강릉시 의회에서 수질오염으로 시작되었으며 장기간 문제해결을 위해 지속적으로 노력하였으나, 2012년 수질개선시설의 수질의 검증 이후 실질개선과 발전문전에 대한협의 등이 단절된 상태로 되어있다.
가뭄으로 인하여 도암댐 물을 활용하자는 애기가 나오고 활용하자는 여론이 형성되면서 여건 변화를 고려해 가뭄극복 하천 생태계 유지를 위한 수질오염의 상태 및 분석에 대한 방안이 필요한 실정이다.
연구의 범위는 송천 지류인 차항천, 대관령천 그리고 용편천을 포함하고 송천 하류 구간 강릉남대천 까지 조사 및 연구를 진행하고 수질측정을 지역은 송천 지역과 도암호 강릉 남대천 지역의 구간으로 하천 유량등 다양한 분야에 대한 조사와 관찰이 필요하다.
