국내 하천수의 수열에너지 활용 가능성 분석 : (2) 회귀수의 수온이 환경에 미치는 영향 평가 = Feasibility Study on the Use of River Water Hydrothermal Energy in Korea : (2) Impact Assessment of the Change in Water Temperature Change of Return Flow on the River Environment

다국어 초록 (Multilingual Abstract)

Utilization of the hydrothermal energy of river discharged water has attracted attention because the hydrothermal energy of sea surface water, which is based on the energy from a temperature difference, was recently assigned as a source of new renewable energy. If the hydrothermal energy of river discharged water can be used as a source of new renewable energy, its general usability should be considered in detail. Hence, the influences of the water temperature of return flow on the river environment, which is used as hydrothermal energy using a heat pump and discharged to the river, need to be determined. This study examined the effects of watertemperature of the return flow on the river ecosystem as well as protected species in the water intake area. The affected area of the ecosystem by water temperature was also assessed by calculating the recovery distance for the return flow water temperature of discharged water from a heat pump. The technical aspect and the acceptance of the stakeholder were also considered. In conclusion, this study could provide basic data for reviewing hydrothermal energy of river discharged water as an energy source.
