CONCEPT 는모댏 MAGOK WATERFRONT Beginning of the 21st century has already indicated the tremendous levels of change in urban Korea. Development with many external cultural influences has accelerated to the levels unseen before. This raises a number of interrelated questions, such as: How are urban parks in Korea changing? What are the sustainable paths towards the development of an urban leisure space in Seoul: mixed use or urban disorder? How can we identify and manifest Korean values into an urban waterfront? What is the formation and attitude of a urban wetland? How an urban wetland can become a park? Our proposal is to form a territory of co-existence between nature and artificiality. From its largest context as the first site of the Han River Renaissance Project to its desires to transform the area of Magok, a strong identity strategy is proposed through water-scapes, transport structures and building types. Underlying the strategy and form throughout the site is the development of eco-formations. These creations of land manipulation both consider the requirements of promoting a waterfront ecology with leisure and park amenities. They perform environmentally through water terracing and an informality of leisure space through a substantial wetlands network. With so much transport and services infrastructures currently being implemented into the site, we looked to take a direct and pragmatic approach to utilizing the given networks. We acknowledge and highlight the importance of local, national and international transport links as fundamental in the design of such a strategic urban structure.

물의 치료 WATER TREATMENT ENVIRONMENTAL MANAGEMENT DISSOLVED OXYGEN
The treatment of the water is carried out in three levels: - Previous Treatment of waters of the 3 smaller creeks to its opening in basin superior - Reed beds (reed beds) in the two basins like treatment of support for the improvement of the quality of its waters - Purification in each cell All the proposed treatments share the fact of being based on systems of beds of macrophyte beds or vegetal filters. The previous and precise treatments work by means of a system of vertical circulation (vertical flow) whereas the surrounding reed beds do it by means of horizontal circulation (horizontal flow).
VEGETATION STRATEGY
First it consists of primary treatment (gravel filter) that retains the solid matters in suspension in the water (Suspended Solids separation), secondary treatment by means of a system of lagooning separated in diverse channels and slope pools established with reed beds that makes circulate the water slowly and create the necessary conditions so that bacteria eliminate the dissolved organic matter.
Ideally the lakes would require the dissolved oxygen level within the impoundment to be maintained at or above 5mg/l in all places and at all times. The 100%ile dissolved oxygen standard would be maintained using water mixing system comprising: - A main network of 50mm diameter. R13 self-sinking armoured rubber pipes. - Webbing of 14mm dia. armoured rubber pipe. - Four compressor stations containing a total of 32 Rietschle DLR100 Zephyr compressors. - Over 300 diffuser heads incorporating unique patented airflow regulators ensuring even release of air from each diffuser irrespective of water depth and distance from a compressor house. - If it becomes necessary to add oxygen to the water an oxygenation barge capable of injecting 400Kg oxygen per hour from an on-board 5 Tonne capacity liquid oxygen storage vessel can be used. WATER QUALITY MONITORING A comprehensive water quality-monitoring programme will be set in place. It consists of 24/7 electronic data acquisition for dissolved oxygen, pH, temperature, conductivity and turbidity at 15 minutes intervals from several monitoring stations. Data will be telemetered to the Magok Harbour Authority office on an hourly basis. The water quality-monitoring deals with conventional laboratory analysis of water nutrients, algal chlorophyll, hardness, some metals and BOD on a monthly basis. E.coli and Faecal streptococci enumeration could be undertaken at 8 sites twice weekly in summer and weekly in winter to inform water recreation users.
Oxygen recovers airing by gravity with small water jumps. The tertiary treatment is partly made through consumption of Nitrogen and Phosphorus in the pool of final storage (floating plants in small masses) that can perform as swimming pool and by the spill of this water in natural substrate by means of irrigation. The solar radiation also enables the disappearance of bacteria in the storage pools. The second, planted on gravel substrate in the edges of basins, makes a secondary and tertiary treatment when penetrating and freely leave the water in these reed beds.
WATERFALL
DEBRIS/LITTER MANAGEMENT Debris deposited in the area each year by the Magok river and the main basins can be collected and disposed of on a daily basis. Waste would be removed from the water using a purpose-made vessel, a floating bulldozer called a Waterwitch, which has a one tonne scoop lifting capacity. Land-based teams would then collect debris from areas inaccessible to the waterwitch. The collected debris can be separated wherever possible for recycling purposes. Of this litter and debris, clean and bulky timber can be used as fuel for a Biomass Boiler at the Harbour.

WATER-WORK DATA
물 관리 GENERAL WATER STRATEGY
The improvement of environmental conditions is essential for the implantation of the project. The colonization of the shores of tributary of Han River and the recreational and sporting use of its waters entails the need for a comprehensive treatment for them to adjust the quality to its use. The strategy of generating landscape part of a unit, an octagonal cell, organized to purify water to be used in its interior. The amount of specific treated water drained towards the basins contributes to the improvement of environmental water surface and therefore the Han River. The urban fabric resulting that forms the shores of the river is the result of the addition of these cellular units differentiated by the programme, weaving a body through an infrastructure catchments, treatment and draining of water and other infrastructure in overlaying uses, etc. The very logic of the movement of water by gravity originates or staged terraced topographies in cellular and global scale.
The strategy of water recycling on global scale: - Optimal water treatment for bath - Optimal water treatment for irrigation - Optimal water treatment for its reusability in construction like water supply of cisterns of WC, washing and dish washing machines, etc - Gray water purification of the new houses with as opposed to basins - Improvement of the quality of the water of basins for recreational use (navigation) - Treatment of the water of run-off of the hill of the east - Purification of activated mud of the plant of preexisting water purification.

TRANSPORT STRUCTURES In principle the urban structures respond systematically to the main transport stations linking Seoul city centre and both Gimpo and Incheon international airports. From these main attractors, a network is formed as a body conditioned to the specific site and local commerce. Roads Along with the current large scale transport infrastructure being undertaken, we look to the condition of the Olympic Expressway with the site as key to establishing a strong riverfront presence. Without disturbing the flow of the expressway, we look to create direct visual access to the Han River. By creating a road intersection from the Expressway to the western edge of the site, we propose reconfiguring Olympic Expressway underground to allow for visual and pedestrian access directly to the river’s edge. There is a hierarchy of roads implemented within the site and link to existing infrastructure surrounding the site. The included on the road plan areas which should provide pedestrian priority/traffic. The way in which we deal with these boundaries and edges will be the key to the success of the scheme. In addition the internal road subsystem encourages slow-speed streets. The roads that meet water will become ‘Jetty Settlements’; suspended pier/jettylike road structures that tread lightly over the lily pads and enable programme to spread over the water.

Cycle network A integrated, comprehensive cycle network is proposed throughout the site. The main circuit follows the shoreline of the two lakes linking all programs. Secondary paths branch off to connect directly to strategic links within each zone. These consider the other transport links in which generous, traffic-free pathways will encourage cycling as the most efficient method of accessing the site. The network program is designed to provide experience through different landscapes and programs. With the water terracing and earth forming, there will be gentle gradients along with varying ecologies from cycling through wetlands to connections with urban train hubs to direct link to bordering street network. In penetrating the site, it will be encouraged to use cycling as the most efficient method. A proposal for a cycle rental network of ‘pay as you go’ is implemented in strategic locations. This system is seen as both for leisure use and for those working in the site and surrounding areas. A strategic framework will be developed along with any development guidelines produced for the site.

Possibilities are corporate office development, restaurants, retail department stores and small business shop owners. The development stripes are also ‘local gateways’ which allow permeability into the site with continuity of green stripes located intermittently. The importance of these stripes is they assist in creating local users and tourist for activating the landscape and water-scapes.

From the larger Magok Development site and the new transport link at 905 Station along subway line 9, these areas allow for the city to infiltrate into the site. Taking strategic moves from the proposed Exhibition facilities complex to the edge of the infrastructural facilities of zone E, a series of development stripes are allocated. Without prescriptive intervention, we would formulate a design guide where mid-rise development with emphasis on retail and commercial sits adjacent to transport hubs.

Each sluice is 9 meter wide. The sluice operation helps protect Magok Waterfront from flooding. When Han river is higher than Magok reservoir, the sluices close to prevent riverwater entering the fresh water of Magok reservoir. When the Han river is lower than the Magok reservoir the sluice gates open to maintain a preferred level of water in the reservoir. C. PUMP STATION The pump station has been relocated on the Barrage. Nearby 400.000 liters of water per second can flow through each sluice gate. D. FISH PASS It allows acuatic fauna to flow in/out the Magok Waterfront.
