Abstract

The main function of artificial wetlands and the largest proportion of the purpose of artificial wetlands created is water purification. The public's interest and demand for water quality increased after the Four major rivers project, and the need for water quality improvement is expected to increase further as the use of waterfront increased due to the improvement of quality of life. Most of the projects focus on only one purpose, and research on the effects of one function is also being analyzed, which undervalues the actual creation of artificial wetlands. Therefore, in order to calculate the comprehensive benefits of artificial wetlands, the effects of flood reduction and water quality improvement were analyzed in this study among the various effects of artificial wetlands along riversides, and the benefits were calculated accordingly. In other words, the effects of flood mitigation and water quality improvement were calculated by comparing the artificial wetlands before and after the construction of artificial wetlands, and the benefits of each of them were calculated.

인공습지의 주요한 기능이자 조성된 인공습지의 목적 중 가장 많은 비율을 차지하는 기능은 수질정화 기능이다. 4대강사업 이후 국민들의 수질에 관한 관심과 요구가 증가하였고, 삶의 질 향상으로 인한 수변공간에 대한 활용도가 높아지면서 수질 개선에 대한 필요성은 더욱 증가할 것으로 보인다. 대부분의 인공습지 조성 사업 시 한 가지 목적에만 초점을 맞추는 게 대부분이며, 효과에 관한 연구도 한 가지 기능에 대한 효과를 분석하고 있어 실제 인공습지의 조성의 가치가 저평가 되고 있다. 따라서 인공습지를 조성에 따른 종합적 편익을 산정하기 위해 본 연구에서는 하천변 인공습지 조성에 따른 여러 효과 중 홍수저감 및 수질개선 기능에 대한 효과를 분석하고 이에 따른 편익을 산정하였다. 즉, 하천변에 가상의 인공습지를 설계 및 조성하여, 인공습지 조성 전·후의 비교를 통하여 홍수저감과 수질개선 효과를 산출하였고 이에 따른 편익을 각각 산정하였다.
