초록

본 연구는 실존이 확인된 국내 구곡원림을 대상으로 문헌조사, 현장조사 그리고 도상작업 등을 통해 구곡을 구성하는 유수 방식과유로 연장거리를 측정하는 한편 유역 및 하천차수 그리고 하천등급을 조사 분석함으로써 수계 상 구곡원림의 유역분포 및 하천형태학적특성을 밝혀 향후 구곡원림의 보전관리 및 활용을 위한 기초자료로 삼고자 한 것이다. 연구의 결론은 다음과 같다.
첫째, 실존이 확인된 총 93개소 구곡원림 중 계류를 따라 내려가면서 전개되는 내림식(하향식) 형태의 구곡은 서울의 이계구곡을비롯하여 총 11개소(11.8%)로 나타났다.
둘째, 구곡별 유하거리 분석 결과, 경북 김천의 옥류동구곡(일명 남산구곡)이 최단길이인 0.44㎞로 나타난 반면, 경북 성주군과김천시에 소재한 무흘구곡의 유하거리는 31.1㎞로 나타나 가장 최장으로 드러났다. 한국 구곡원림의 평균 유하거리는 6.24㎞였으며표준편차는 4.63㎞로 나타나 곡류형과 계곡형 간의 편차가 심한 것으로 나타났다. 또한 14개소(15.1%) 구곡원림은 댐 건설로 인해일부가 수몰된 상태로 밝혀졌다.
셋째, 구곡원림의 수계역 분석 결과, 낙동강수계가 52개소(55.9%)로 압도적이었으며, 다음으로 한강수계 27개소(29.0%), 금강수계9개소(9.7%) 그리고 영산강·섬진강수계 5개소(5.4%) 순으로 확인되었다. 한강권역에 입지한 구곡원림은 모두 한강수계로 분류되었으며낙동강에 입지한 구곡원림은 낙동강남해권수계 5개소와 낙동강동해수권수계 2개소 등 7개소를 제외한 하천은 모두 본류인 낙동강수계로분류되었다.
넷째, 구곡원림이 입지한 유로의 하천차수를 종합한 결과, 본류 구간을 구곡의 거점 유수로 삼은 구곡은 한강수계의 3개소, 낙동강수계의5개소, 금강수계의 2개소 그리고 영산감/섬진강수계의 1개소 등 총 11개소(11.8%)였으며 제1지류에는 35개소(37.6%), 제2지류에는28개소(30.1%), 제3지류에는 17개소(18.3%)로 나타났다. 그리고 제4지류에 입지한 구곡원림은 한강수계의 철원 용화천에 설정된 태화오곡과 낙동강수계인 영천 횡계천에 설정된 횡계구곡으로 분석되었다.
다섯째, 구곡원림이 입지한 하천의 하천등급 분석 결과, 전체 구곡원림이 입지한 하천의 등급은 국가하천 13개소(14.0%), 지방1급하천7개소(7.5%), 지방2급하천 73개소(78.5%)로 밝혀졌다.

In this study, the water flow system by measuring the flow-way type and distance of flow path that composes the Gugok through literature survey, field survey, and map work on Gugok gardens in Korea whose existence has been confirmed, while investigating and analyzing watersheds, river orders, and river grades. It was intended to reveal the watershed distribution and stream morphological characteristics of the Gugok gardens and to use them as basic data for future enjoyment and conservation of the Gugok gardens. The conclusion of the study is as follows.
First, Of the 93 Gugok gardens that have been confirmed to exist, it was found that 11 places(11.8%) were found to have a descending(top-down) type of Gugok that develops while descending along a stream.
Second, As a result of analysis of the length of the flow path for each valley, Okryudonggugok(玉流洞九曲, Namsan-gugok) in Gimcheon, Gyeongsangbuk-do was found to have the shortest length of 0.44km among the surveyed valleys, while the flow distance of Muheulgugok(武屹九曲) located in Seongju-gun and Gimcheon-si, Gyeongsangbuk-do was 31.1km, showing the longest flowing distance. The average flow path length of the Gugok Garden in Korea was 6.24km, and the standard deviation was 4.63km, indicating that the deviation between the ‘curved type’e and the ‘valley type’ was severe. In addition, 14(15.1%) Gugok gardens were found to be partially submerged due to dam construction.
Third, As a result of analyzing the waters area where Gugok garden is located, the number of Nakdong river basins was much higher at 52 sites(55.9%), followed by the Hangang river basin at 27 sites(28.7%), the Geum river basin at 9 sites(9.7%), and the Yeongsan river and Seomjin river basins at 5(5.4%).
Fourth, All Gugok gardens located in the Han river region were classified as the Han river system, and the Gugok garden located on the Nakdong river was classified as the main Nakdong river system, except for 7 places including 5 places in the Nakdong Gangnam Sea water system and 2 places in the Nakdong Gangdong sea water system. As a result of synthesizing the river order of the flow path where Gugok garden is located, Gugok, which uses the main stream as the base of Gugok, is 3 places in the Hangang water system, 5 places in the Nakdong river system, 2 places in the Geumgang water system, and 1 place in the Yeongsangam/Seomjin river system. A total of 11 locations(11.5%) were found, including 36 locations(38.2%) in the first branch, 29 locations(31.2%) in the second branch, and 16 locations(17.0%) in the third branch. And Gugok garden, located on the 4th tributary, was found to be Taehwa Five-gok(太華五曲) set in Yonghwacheon Stream in Cheorwon in the Han river system, and Hoenggyegok(橫溪九曲) in Yeongcheon Hoenggye Stream in the Nakdong river system.
Fifth, As a result of the river grade analysis of the rivers located in the Gugok garden Forest, the grades of the rivers located in the Gugok garden were 13 national rivers(14.0%), 7 local first-class rivers(7.5%), and 74 local second-class rivers(78.5%) was shown.
