Abstract

The purpose of this study is to examine a monitoring method, management zones, and maintenance strategies for water friendly facilities in urban streams after the completion of ecological restoration projects. Maintenance monitoring items are composed of 'use space& facilities', 'trails& bike roads', 'access', and 'boards'. The evaluation standards of water friendly facilities are 'maintenance conditions', 'safety', and 'usage level' which are rated as 'good', 'moderate', and 'poor'. Through a field survey and evaluation of 15 stream sections in Jeonjucheon,the management levels of each water friendly facility are determined as 'priority maintenance', 'general maintenance', 'maintain/remove', and 'remove'. Based on the evaluation results, management zones and maintenance strategies are proposed for each stream section. As a results, the stream sections of J2, J3, J4, and J9 which have 5 to 9 facilities with 'priority maintenance' are determined as 'intensive management zone'. The stream sections of J5, J6, J7, J8, J11, and J14 which have 1 to 3 facilities with 'priority maintenance' are determined as 'regular management zone'. The stream sections of J1, J10, J12, J13, and J15 which have no facilities with 'priority maintenance' are determined as 'minimum management zone'. The process of monitoring & evaluation system and determining management zones can be applied to establish a systematic maintenance plan for water friendly facilities by participation of governance in the future.

본 연구의 목적은 도시하천의 생태복원사업 이후 친수시설의 모니터링 방법을 연구하고 그 결과를 바탕으로 관리구역의 설정과 유지관리방안을 제시하는데 있다. 이를 위해 친수시설의 유지관리모니터링 항목을 '이용공간 시설물', '산책로 및 자전거도로', '접근로', '안내판'으로 구분하였다. 각 친수시설의 평가는 '관리상태', '안전성', '이용정도'를 기준으로, '양호', '보통', '불량' 등급으로 구분하였다. 전주천을 대상으로 500m간격의 총 15개 구간을 조사 및 평가하여 친수시설마다 '우선관리', '일반관리', '유지/제거', '제거' 여부를 결정하고 이를 바탕으로 구간별 관리구역설정과 유지관리방안을 제시하였다. 전주천에서 '우선관리'가 필요한 시설이 5~9개로 나타난 J2, J3, J4, J9 구간은 '집중관리구역', '우선관리'가 필요한 시설이 1~3개로 나타난 J5, J6, J7, J8, J11, J14 구간은 '정기관리구역'으로 설정되었다. '우선관리'할 시설이 없는 J1, J10, J12, J13, J15구간은 '최소관리구역'으로 설정되었다. 본 연구의 모니터링 및 평가, 유지관리구역 설정과정은 향후 거버넌스가 참여하여 하천 친수시설물의 체계적인 유지관리계획을 마련하는데 적용될 수 있다.
