As part of the waterway restoration to renew traditional urban area, this paper is to assume and research Gyoseocheon(Gyoseo waterway) in Late 1960s Cheongju Korea. The main stream of Gyoseocheon flew from Sangjwagol(the head of the valley) of Uam Mt. to the north gate under Cheongju castle at first, and meandering from Sangdang Park, flew through Sudongseongdang and Bangadari Road to Musimcheon since open railroad of 1920s. This waterway, the eco-friendly figure of Gyoseocheon, that flew to inside the downtown with a planted tree and that is open space was so. The sub stream of Gyoseocheon originated in Seoundong and Tapdong were divided into two parts. One was to join the main stream of Gyoseocheon on Sangdang Park via Munhwadong, and the other was to join the sub stream of Musimcheon at northwest corner via south and west gate of Cheongju castle. This waterway as branch sewer were built into the road culvert.

This technology is to let rainwater flow into a waterway that is located side gutter of a street with blocking garbage including cigarette butts at the same time. The first waterway is located beside the sidewalk and it enhances the water circulation in a city. This waterway is filled with aggregates and filter media, which removes fine dust that is washed out of the street and let water flow down to the earth. The second waterway is located beside the street and it retains rainwater temporarily with decreasing its flow speed. The second waterway shall reduce flooding damages by avoiding bottleneck situation in the street inlets and storm water pipelines which is the main causation of flooding in a city.

In this study, to evaluate the characteristics of the pollution in the major inflow tributaries and major environmental facilities in the watershed of Ara waterway, An inflow flow rate measurement and water quality analysis were conducted during dry and rainy seasons. In addition, the flow rate measurement, water quality analysis, and pollutant load at each monitoring point were compared and evaluated. Influx of BOD5, T-P and T-N into the tributaries of the ARA waterway watershed, excluding the Gulpo river watershed, during dry season were only 0.007%, 0.005% and 0.004% respectively of the incoming loads in the entire ARA waterway basin. In addition, it was confirmed that the discharge pollutant loads during rainfall event was about 440 times more for BOD5, about 545 times on T-P, and about 23 times on T-N in comparison to the pollutant loads during the dry days. When the Gulhyeon rubber dam was deflated, the discharged pollutant load during a rainfall was higher than the estimated load at the G7 monitoring point because the deposited pollutants from the upstream riverbed flowed down. Therefore, during a rainy season, it is necessary to manage the influx of high-load water pollutants from the overflow and deflation of the Gulhyun rubber dam as well as to find a strategy to reduce the pollutant loads in the Gulpo river watershed.

Ganggyeong, a city which is located at riverside of Geum River, played a role to connect the inland cities and the coastal cities through the Geum river waterway. In Chosun dynasty, Ganggyeong was one of the three major markets in Korea, and at the same time, it was one of the two river docks in Korea. However, after the railway was installed in Korea, railroad was more important than waterway in transporting logistics and in 1911 Honam railroad and Ganggyeong railway station was installed. Thus it was necessary to reorganize urban structure of Ganggyeong city from the traditional river-dock city to modern railroad city. In addition, urban infrastructure to prevent flood damage was needed because Ganggyeong suffered from floods and water shortages every year. Therefore, between 1910s and 1930s large-scale social infrastructures including road, water and sewage system, river bank, floodgate was constructed not only to revitalize the declining city but also to prevent flood damage and water shortages that hinder urban development. The installation of urban infrastructure has enabled the urban expansion and development of Ganggyeong city, and it is still served as a basic urban structure.

The Gyeongin Ara Waterway is a regional development project designed to transport cargo by sea and to utilize the surrounding waterfront area to enjoy tourism and leisure. It is being used as a space for demonstration projects for urban air transportation (UAM), which has recently been attracting attention, and various efforts are being made at the local level to strengthen cultural and tourism functions and revitalize local food. This study examined the perception and trends of tourism consumers on the Gyeongin Ara Waterway before and after the outbreak of COVID-19. The research method utilized semantic network analysis based on social network analysis. As a result of the study, first, before the outbreak of COVID-19, key words such as bicycle, Han River, riding, Gimpo, Seoul, hotel, cruise ship, Korea Water Resources Corporation, emotion, West Sea, weekend, and travel showed a high frequency of appearance. After the outbreak of COVID-19, keywords such as cafe, discovery, women, Gimpo, restaurant, bakery, observatory, La Mer, and cruise ship showed a high frequency of appearance. Second, the results of the degree centrality analysis showed that before the outbreak of COVID-19, there was increased interest in accommodations for tourism, such as Marina Bay and hotels. After the outbreak of COVID-19, interest in food such as specific bakeries and cafes such as La Mer was found to be high. Third, due to the CONCOR analysis, five keyword clusters were formed before the outbreak of COVID-19, and the number of keyword clusters increased to eight after the outbreak of COVID-19.

This article analyzes the publicness of early modern cities and the character of samurai residences as urban dwellers through the water supply and use of the Edo period in Japan. Firstly, in Edo, a megacity with a population of about one million, the Shogunate organized samurai residences (mainly those of feudal lords, Daimyo) into geographical organizations, and samurai residences paid for the repair of water facility and the water fee, just the same as the townspeople. Next, in Fukui (provincial castle town), samurai residence (Daimyo's vassal) organization for waterway didn't exist. The samurai residences were relieved of the burden of maintaining the waterways due to poverty. And, before the later Edo period, samurai vassals were not punished for violating the rules on water use, but they were eventually included in the punishment. The gap in feudal status between samurai and townspeople narrowed. It was a process of creating a modern urban society composed of equal dwellers. Although Edo and Fukui belonged to the same category as castle towns, the urban publicness and the position of samurai residences were different due to their dissimilar political positions as the Shogunate capital city and the Daimyo's provincial castle town.

This paper examined the changes in flow patterns due to a blockage of tidal currents in the sea areas between Incheon North Port and Yeomha Channel when it would be influenced by the construction of the Incheon North Port Yeongjongdo dredged soil dumping ground and Incheon Bay tidal power plant. The numerical simulation was performed for three cases: before and after constructing the Incheon North Port Yeongjongdo dredged soil dumping ground and after the construction of the sea-dyke on the east side of the Incheon Bay tidal power plant. The simulation results showed that the tidal directions and currents velocity were similar before and after the construction of the Yeongjongdo dredged soil dumping ground. After the construction of the East Sea-dyke of Incheon tide power plant, however, the tidal currents patterns changed significantly due to flow blockage toward Gyeonggi Bay. The main flow was formed in the north-south direction, and the tidal currents velocity increased slightly on the downstream areas (A,B,C) of Hodo, which is the entrance of the Ara Waterway. The tidal currents at the mouth(D) of Yeomha Channel decreased significantly. The tidal currents of the west side of Se-eodo and the east side of the sea-dyke were rotary currents. The results of this study will provide basic data for the environmental impact assessment and the operation of the Gyeongin Ara Waterway.

Nihombashi is located in the central area of Tokyo, Japan. Tokyo has been the capital in Japan since the Edo period, which started approximately 400 years ago, and has accepted a variety of cultures, human resources, businesses for the last 400 years. This has resulted in building up the present prosperity. The Sumida River, one of the symbols of Tokyo and its tributaries including the Kanda River and the Nihombashi River, flows through the Nihombashi district. The river and tributaries used to benefit to the City of Edo. Due to the economic development and the industrial growth in Tokyo, however, they were polluted and lost their functions. In 1960s, approximately 40 years ago, the Sumida River became so dirty that local citizens kept away from it. The Nihombashi River was covered with an expressway, which was obscuring the river view. Since 1970s, local communities have proposed to rehabilitate rivers in Tokyo successively, and have proceeded with measures for river floods, improvement of sewage systems and construction of water purification facilities. Consequently, the quality of the river water was considerably improved in 1990. The stagnant rivers were turned into ones that local citizens were physically able to come close by. Today, restoring of the environment and the appearance of the city in the old days, Nihombashi district has been proposed as a model city of the future, which is alive with history and culture and harmonizing with rivers. The concept is "To Create, To Reserve, To Restore." This paper introduces a case study of the urban development, in which the local communities and public authorities collaborated with and proposed a brand-new style of the urban city harmonizing with the environment.

This study is foundation study to understand the Location and the composition of Joseon Royal Tombs, the purpose is to bring light on the types of Sinro Eoro in Joseon Royal Tombs. The type was grouped into Regular type and Irregular type by relations with the approach way, Hongsalmun and Jeongjagak, and the Irregular type was grouped into Curved type and Divided type. The making pattern of Sinro Eoro was divided into three period, the former period, the transition period and the latter period, by the length and the Irregular type. The Regular type was affected by the length of Geonwonreung's Sinro Eoro as the minimum standard in the former period. The result of examining the Irregular type's present condition in Jeongreung, Hyeonreung, Mokreung, Jangreung and Yeongreung, narrow topograph and the waterway were important factors to decide the type. In other words, the type of Irregular Sinro Eoro was constructed by a topography and a waterway in the length of Geonwonreung's Sinro Eoro as the minimum standard.
