UN Sustainable Development Goals

Abstract Floods are the most common natural disaster in the world, affecting millions of people globally. The increase in urbanization, population growth and changing climates all contribute to the frequency of flooding events and their impact on our urban environments. Located in Nanjing, China, this project investigates the lower reaches of the Yangtze River, where the water network is dense, known as "the land of fish and rice". The site is densely urbanized, dominated by factories, towns and cities and consequently is affected by flood with years. The government has invested heavily in large scale engineering projects to try and control the floods, but rapid urbanization, degraded ecosystems and climate change continue to present flood risk, posing a major challenge to the communities adaptation strategy. This design research project will explore how the design and consideration of the surrounding ecology, community and culture can alleviate the local flood problems, improve the surrounding living environment and provide increased economic opportunities for the community. As a landscape architect using the theory of low impact development (LID) the project will listen to the voice of the local community, explore the history and culture of the river and develop two different ways of using the site for users. Through the intervention and design of landscape within site, the local flood problem can be alleviated, the local ecology can be improved, more people can be attracted to the site and the surrounding community can be activated, resulting in ongoing positive economic and cultural benefits for local residents.

1.2 IN THE WORLD AT PRESENT

Flood season: June and July

Especially in China, the Yangtze River as the mother river across China, causes a variety of flood problems. With the global warming, the water level of the lower reaches of the Yangtze River is rising year by year. Nanjing, as a typical case, is a city with serious flood.

Water level: up to 6 meters

1.3 THEORETICAL FRAMEWORK Floods cause many problems. Throughout the history of water control in China, it always is better to dredge than to block. As a modern theory of rain and flood management, many countries have cited and updated LID. For example, in China, the concept of sponge city was created based on national conditions. Flood control needs to be adjusted to local conditions, but under the guidance of basic theory, useful technology is universal. It is hoped that through the intervention of landscape to the site, the local flood problem can be alleviated, the local ecology can be improved, more people can be attracted to the site, and the surrounding community can be activated, so the economic and cultural aspects are able to be developed.

Storage and utilization

Lid low impact development is an ecological technology system that can easily realize urban rainwater collection and utilization. Its key lies in in-situ collection, natural purification, nearby utilization or groundwater recharge. It mainly includes: ecological grass planting ditch, sunken green space, rainwater garden, green roof, underground seepage storage and permeable pavement.

3.4 SITE ISSUE By investigating the history of the site and listening to the voices of residents in the surrounding communities, we can gain a deeper understanding of the site and discover existing problems. There are many problems caused by floods. Throughout the history of water control in China, it is better to dredge than to block. As a modern theory of rain and flood management, LID has been cited and updated by many countries.

ISSUE The flood will wash out the garbage and dust in the city, causing ecological pollution and a bad urban environment. When the water level is too high, the main roads in the old city are flooded. In the rainstorm, the rain can not quickly infiltrate, and it is difficult for the community near the river to travel.

FACT Transportation

Living space

Ecology During the flood season, a lot of rainwater has no place to infiltrate and store, the river channel is narrow, the riverbank is too hard, and the flood has squeezed the living space of residents.

Due to the flood, a lot of space is used for embankment, people lack the landscape space and infrastructure.

5.2 MASTER PLAN Downstream

Downstream

Midstream

Upstream

This is the plan of the entire Nan River project. The length of the river is 9.3 kilometers. Along the river is mainly a large number of residential areas and a small part of business. The design follows the LID principle, aiming to have cleaner water and sanitation while achieving sustainable cities and communities. Therefore, after conducting a systematic survey and analyze the site, to achieve two goals, considering ecology, water and community, using appropriate landscape strategies, and combining the existing environmental background to design.

Upstream

The upper reaches are flooded areas, and more attention are paid to design rainwater management and post-disaster water purification. The embankment in the middle reaches is harden and residents lack space, so they are more inclined to the increase of infrastructure and commerce and the planning of landscape embankment. The lower reaches more attentions are paid to water conservation.

5.4 MASTER PLAN This is the plan detail of the north of the Nan River. The north is basically a new urban area, with good urban planning and underground pipe network. At the same time, it has good terrain and wide river bed geographically. There is no problem of flood and waterlogging in this part. The economy of the area is relatively developed, and the residents pay more attention to the pursuit of spiritual development and better landscape environment. There are few green spaces along the river. There are some green areas in the West and serious hardening in the East. The design mainly focuses on the design of riverside road to provide better Lake tour route and riverside landscape for the surrounding residents.

5.4 MASTER PLAN This is the plan detail of South of the Nan river. In the south, the old and new cities are mixed, the population attribute is complex, there is no good urban planning and underground pipe network, at the same time, the riverbed is narrow, and the buffer area is small. In addition, the river end was cut off by a canal. As the river goes south, the problem of flooding and waterlogging becomes more serious. The economy of this area is relatively unbalanced. The worse the floods, the worse the local economy. Residents pay more attention to flood control and transportation during the flood season, hoping to have supporting infrastructure and landscape space.

30 M

The river bank of this plot is seriously hardened, but more wasteland along the river can be used to increase the buffer zone, and it is designed as a citizen park and landscape wetland to provide residents with space and purify water.

SITE ONE - DESIGN IMPLEMENTATION > SITE ONE: Sunken Civic Raingarden Park The inspiration of the project comes from "Room for river", the precedent of river in Holland. This strategy has flexible and adaptive tidal space, and can generate multi-functional space according to different water levels. There are many ways to hold and store water. Give the flood more space to allevite flood.

Alleviate the flood and improve the related problems caused by flood

Improve the living environment of communities along the river

Before the start of the project, some endangered houses along the river needs to be demolished. In addition, reduce the original top road and set up underground rainwater tanks. The project combines the original shape and area limitations of the site to form a strip-shaped space with three sunken green spaces and an entrance sunken plaza. These sinking spaces will be used as reservoirs during heavy rains. Used to store surface runoff that is too late for the bottom row. At the same time, it can be called a good space for landscape communication when it is sunny.

Strategy 1: Demolish the riverside endangered houses in the flooded area

Strategy 2: Reduce the original embankment Top Road and remove the hard embankment

SITE TWO - DESIGN IMPLEMENTATION > SITE TWO: RIVERSIDE WETLAND PARK Site 2 is located at the southern end of the Nan River. At present, it is a large area of unplanned wasteland. The project follows the design principles of LID and is committed to two goals. According to the site is located at the end of the upstream, the establishment of wetlands can better conserve water and purify sewage.

Alleviate the flood and improve the related problems caused by flood

The water source in the project mainly comes from the Nan River water drawn by the pump and the stagnant water in the original ditch. After precipitation, exposure to oxygen, water drop, and a series of natural essence, the source of water will be replenish into the Nan River, and ultimately achieve the natural purification of water quality.

SITE THREE - DESIGN IMPLEMENTATION > SITE THREE: RIVERSIDE LANDSCAPE COMMERCIAL STREET Site 3 is located in the southern part of the Nan river. At present, there is a certain amount of landscape greening on the west side. On the east side is a rigid embankment. Fortunately, the terrain on the east side is relatively high, and the government has also increased the height of the embankment on the east side, so there is no flooding problem during the flood season.

Alleviate the flood and improve the related problems caused by flood

Improve the living environment of communities along the river

In addition, this area has a good urban landscape and 500-meter-long street shops along the river. The project is committed to building a good riverside landscape and open riverside shops in this part. After analyzing the relatives of the surrounding residents, I learned that people feel that the Nan river Basin lacks entertainment and social space after off work. The project decided to build a meter-length bar street in this section to improve the good riverside landscape during the day and enjoy the beautiful city landscape at night, also, provide surrounding residents and tourists with a resting place after off work. At the same time, after investigating similar rivers, water entertainment activities such as kayaking have been set up. Used to increase the local economy and attract people. Also, the project will begin to attract investment in the first stage and construction will be carried out in the second stage.

Name: Mrs. Wang Age: 65 Work: Unemployed Residence: Nan river Community Family situation: The children are employed in other city, and they lived in Nan river community with her husbands for nearly 30 years Daily activities: buying vegetables and cooking, chatting with neighbors and playing cards

According to the opinions of residents, the area has added a lot of supporting infrastructure, such as pavilions, and outdoor tables and benches.

The newly built road can be better drained. Even though it rained yesterday, the ground is still very dry. My favorite activities after retirement are playing cards and chess. Before there was no suitable venue, everyone found an open space on the side of the road. Now they can play cards in the pavilion.

After playing the cards, I will go to the senior citizen's activity venue to exercise for a while, then I will go to the market to buy something, and then go home to cook dinner. After eating at home at noon, I saw from the window that there were many people basking in the green space in the newly built park.

Many multi-functional venues have been added around Nan river, such as senior activity venues, children's playgrounds and citizen squares.
