In this study, we analyzed the changes in the topographical landscape and the sedimentary environment to evaluate the ecological value of the Dongcheon Estuary and protect the wetland, and presented the conservation management method of the Dongcheon Estuary. Based on the result of topographical landscape analysis, agricultural land tended to decrease continuously, and artificial structures gradually increased. Moreover, in sediment analysis, the Dongcheon Estuary showed both the characteristics of river sediments and coastal sediments, and in some areas problems such as acidification and nutritional imbalance appeared. Therefore, in order to protect and manage the Dongcheon Estuary with high ecological value, it is necessary to limit the development around micro topography and minimize the artificial damage in the Dongcheon Estuary. In addition, efforts such as securing facilities for reducing pollutants and freshwater wetlands for pollutants, that flow in from nonpoint pollutants are required.

This research is attempted to investigate Dongcheon-rock inscription- to understand symbolic meanings from inscribed texts and to find its construction purpose. For the investigation, 25 target areas were selected for field exploration and literature review regarding Dongcheon were also performed. Several design characteristics of Dongcheon are as follows: First, Dongcheon has four criteria according to creation purpose: residential type(家居地型), hermitage type(隱棲地型), nature excursion type(山水遊覽型), aesthetic scenery type(勝景型), moral training type(修身型) and spiritual discipline type(修道地型). This category shows that Dongcheon is constructed at residential area, shelters, and place for leisure, mortal training and spiritual discipline. Second, Dongcheon is also classified by its location: location on village entrance in a deep forest(深山同口型) and location on near stream(溪流隣接型); location on near stream has also two types(連繫型, 單一領域型): location on an independent territory and location horizontal ground(平地型). Through garden creators' managing their garden in forest, valley and scenic spots, they pursue utopia. Third, naming is a way to create new landscape places. By naming a certain natural landscape as Dongcheon, the landscape is symbolized as utopia, appearing fairyland. Designer's desire and thoughts are saturated in Dongcheon.

This work is to describe the geomorphological landscapes of of Dongcheon-gugok in Korea, and attempts to develop a basic data for traditional natural heritage. Dongcheon-gugok is a union of natural lanscape and human mind-activity. Therefore the study of natural landscape, which consists of geomorphological landscapes, provides a basic data for the use and conservation of traditional natural heritage. Dongcheon-gugok in Korea is almost distributed in the valley of mountainous areas of Taeback and Soback Mountain Ranges. The bedrocks of the areas of Dongcheon-gugok are almost granitic rocks and sedimentary rocks. The landscapes of Dongcheon-gugok is characterized by narrow meandering valley, so Gugok means nine-bended river. The elements of the geomorphological features is a broad flat rock with sheeting joints, joint-block seperated large blocks or tor, steep slope and rocky cliffs, pool, ripple, large or small scale waterfall, pot-hole, etc.

This work is to describe the geomorphological features of Dongcheon-gugok in the Eastern Part of Gyeongsang Province, and attempt to develop a basic data for traditional natural heritage. The bedrocks of the study area is typically sedimentary rocks of Gyeongsang Series. Dongcheon-gugok in the study area is almost distributed in the valley of Taebaek Mountain range in Gyeongbuk Province. These valleys almost belong to tributaries of Nakdong River, and are characterized by narrow meandering valley in the moutainous region. Dongcheon-gugok in the study area is located in these valleys with steep slopes or rocky cliffs. And there are pools, point-bar with sands and gravels, riffles, etc in the river valley. Ancesters named these landscape with Jeolbyuk(rocky cliff), Bong(peak), Dam(pool), Tan(ripple), Cheonsa(point-bar), Pok(waterfall), Dae(hill), etc.

The culture of Gugok (九曲) and Dongcheon (洞天), which tries to reach the ideological culmination in Confucianism, was widespread throughout the Joseon dynasty. This was an extension of the spirit of studying and honoring Zhu Xi (學朱子, 尊朱子); thereby, Confucian scholars in Joseon expressed the will to follow the teachings of Zhu Xi (朱子) and comforted themselves that they were in the course of attaining the truth. As a realization of this expression of will, scholars designated and operated various scenic sites as Gugoks, following the example of Zhu Xi's Mui Gugok (武夷九曲), and Dongcheons, as a representation of the utopia. These designations are widespread nationwide, with around sixty Gugok locations that have now been reported in academia. However, the actual number of Gugoks exceeds this number, and many of them are currently not identified concerning the exact locations. Therefore, the purpose of this study is to identify the locations of Gugoks and Dongcheons scattered around Seoul, Gyeonggi and Gangwon regions. For the coordinates of Gugoks and Dongcheons, this study referred to the literature, web search and the books published by local cultural institutes. Based on the collected information, the researchers conducted field trips to investigate whether the record exists as a real location and, if so, acquired their coordinates. This study also provides the tables of Gugok or Dongcheon that only exists in the imagination, existed before but now are lost, or are inaccessible. Eight locations in Seoul, Gyeonggi, and Gangwon regions are understood as Gugok. Among them, Gogun Gugok and Okgye Gugok have relatively clear locations and records. Byeokgye Gugok and Suhoe Gugok, on the other hand, has many locations and titles overlapped, and their established time and managers are unclear. As for Ui Gugok in Seoul, it is known to be set by Hong Yangho, but some parts of its locations are confirmed, others are in dispute, and many locations are damaged. Thirty-eight locations in Seoul, Gyeonggi, and Gangwon regions are understood as Dongcheon. There are sixteen Dongcheons in Seoul area. Among them, those including Dohwa Dongcheon, Yangsan Dongcheon, and Ssangnyu Dongcheon actually exist but are forbidden to be accessed. There are thirteen Dongcheons in Gyeonggi area. The exact location of Onsu Dongcheon cannot be confirmed because of the development; Gwirae Dongcheon has historical records, but the actual existence cannot be confirmed. There are nine Dongcheons in Gangwon area. The researcher judged that Hwaeum Dongcheon is the misspelled record of Hwaeumdong Jeongsaji (華陰洞精舍址), which is located at the upstream of Gogun Gugok.

This study aims to reproduce of Anuisamdong's landscape structure and improve the value of Scenic site. It was extract main spot from Geography book published by government in the 19th Century. And analyzed landscape architecture of Dongcheon. Extract main spot from Geography book published by government. Consequently, Hwarim-dong main spot 6 places, Simjin-dong main spot 9 places, and Wonhak-dong main spot 25 places were identified. Hwarim-dong's main spot was divided into 3 places of pavilion and scenery, respectively. Simjin-Dong's main spots was all that natural elements as a scenery. Wonhak-dong's main spot was the most elements of the Anuisamdong in geography book published by government. Hwarim-dong was pavilion-based scenery area complex, Simjin-dong was continues scenery spot along the valley, and Wonhak-dong was hybrid distribution that landscape structure. Each dongcheon in Anuisamdong was created a separate area through isolated geographical, visually for structure of collectively means. Also, a narrow entrance and enclosure topography are areas which arouse atmosphere of paradise. In addition, Aunuisamdong's landscape structure, which was previously divided into individual Dongcheon, was expanded into a single integrated landscape structure of Dongcheon. This is different from the general landscape development of common Dongcheon with the same starting and ending points and sightseeing routes.

In this study, we suggested 4 plans to reduce non-point pollutant sources in Dongcheon and analyzed their controlling effects by water quality modeling, XP-SWMM. To do this we identified the influx of non-point pollutant sources to the initial rainwater through the water quality survey in the river and analyzed the causes of them at major locations, and suggested 4 kinds of plans reducing non-point pollutant sources. Plans reducing the non-point pollutant sources through cleaning the industrial road around the river(plan A), through a separate treatment facilities like the gutter(plan B), through installing treatement facilities(plan C), or through combing plan B and C(plan D) were analyzed using XP-SWMM model. The analysis showed that plan A, B, C and D reduced non-point pollutant sources average 21.7 %, 24.7 %, 49.3 %, 56.7 % respectively. Therefore, the water quality pollution in Dongcheon due to the influx of non-point pollutant sources is considered to be reduced effectively though cleaning the road, installed at the exits of paddy or factory basins, invasion type facilities or equipment-type facilities.

Initially from the Taoist scriptures, 'Dongcheon' is a term that can be regarded as a symbolic place in the real world for the enlightened ones who received relief and peace by restoring the human nature taught in the Confucian school. The long for an ideal world apart from the reality embodied as the labeling some places 'Dongcheon,' and the term was used to refer to a scenery where the ideal fairyland is reproduced. Besides, 'Dongcheon' was a term often used by Confucian scholars for various purposes including the attachment to the nearby landscapes, expressing homogeneity and superiority through placeness and the beautification of settlement spaces. This paper is the result of a field study on 'Dongcheon' in the Gyeongsang-Do. The research was conducted from March to August 2018, and we carried out firsthand location surveys on Dongcheons, of which some were lost, others were fairly preserved, and still others could not be located as only their existences were passed down orally. According to the field survey, there were total 111 inscriptions or engravings on the plates in Gyeongsang-Do that include the term 'Dongcheon.' There were 79 'Dongcheon' inscriptions confirmed in the Gyeongsangbuk-Do region: twenty in Yeongju-City, sixteen in Bonghwa-Gun, eleven in Andong-City and seven in Yeongyang-Gun and Ulgin-Gun. Among them, two were in the form of a wooden sign, and six were erected as rock signposts. Fourteen stops reported in the literature were lost or unidentified. Also, among the sixteen signs in Bonghwa-Gun, nine were cursive engravings. Meanwhile, there were 26 Dongcheon inscriptions in the Gyeongsangnam-Do region. Hamyang-Gun and Sancheong-Gun anf Hadong-Gun each housed three inscriptions, and seven places were in the form of rock signposts. 'Hwagaedongcheon' and 'Geumsandongcheon' could not be identified in inscriptions although they appear in Jibong Yuseol and Taengniji with stories of Choi Chiwon. The significance of this study is as a reference for future researches in traditional scenery, epigraphs, or as primary data that helps cultural exploration in the region.

This study aimed to analyze water cycle at Taehwa river, Dongcheon, Hoiya river and Cheongryang cheon in Ulsan city using CAT model developed by Korea Institute of construction technology. To apply CAT model, we separated Teahwa river into 25, Dongcheon into 11, Hoiya river into 17 and Cheongryangcheon into 5 subbasins and discriminated between contribution runoff basins and source basins. The results of water cycle analysis performed using rainfall datas measured from 1975 and 2008 and hydrologic datas of change of land use etc. were that surface runoff increase and interflow decrease, caused by the increase of impervious area. The increases of surface runoff at the basin of Taehwa river and Dongcheon which is a tributary of Taehwa river were small and similar to each other respectively as 1.7% and 2.4%, and increased high rate of 3.2% and 7.7% in Hoiya river and Cheongryangcheon including subbasins which are having high rate of urbanization.
