Diploma 「Landscape of 香雨 (KOUU) ー Construct a Green Infra Network around Kanda River Basin ー」 Japanese people have more than 400 words about rain. One of them 香雨 (KOUU) is old Japanese word and means beautiful respectable rain. These words show that Japanese people have had close relationships with rain since long time ago. In this proposal, re-construct the relationships between water, green and us by Green Infra system.
01 What is Green Infrastrucuture? ⑴Definition for this Work ¦to Connect human and Nature "Greenn Infrastrucuture" is defined as constructing infrastructure based on ecological networks and land. Nowadays, our society is filled up with grey infrastructures. The way of Green Innfrastrucuture can help to connect potentials of nature with our human society.

⑶Nature and Human ¦ the Goal of this Diploma Work
Begining（∼Edo era） Nature is filled up with ecological systems. Human lived in these systems. We took some benefits from them though, we didn t take too mush of it.
Developing Society With developing our civilization more, our society got bigger. It had a presense in nature. Then we took more benefits than in Edo era.
Industrial Evolution
Getting too much benefit from eco system collapsed the balance in nature. Because the attractive force from our society to eco system was too strong, our society was pushed away to the edge of nature system. Moreover, the green infrastructure system became weak.
Isolation of Us
Because of the industrial evolution, our society has been almost isolated from nature. In addition, the green infra system has been lost and we can t live together with any disasters and environmental changes. And we destroy nature a lot.
Future
Remarking Green Infra system would make human societies and ecosystems get closer again. Then human society takes benefits from eco systems. And our society with green infra gives good influences for ecosystems.
02 Background
03 Construct a GI Network at Kanda River Basin
⑴Environmental change by the global warming ①Climate Change Heat island, Swealtering night(the night, that temperature is more than 25℃),Heat injury, Influence for the ecology
②Increase of stormwater Cause of mudslides or floods, influences for agriculture
⑴6 functions of stormwater management
⑵ 12 Functions of Green Infrastructure ③Squalls Because of too much rainwater over the capacity, conventional infrastructures doesn t work.
①Stormwater Management Stormwater is controled by using raingardens or greenway to infiltrate, flow and keep water.
②Resilience from Disasters In the case that a mudslide occurs, trees catch earth and the sand. To prevent a mudslide, trees are also used to catch rainwater not to flow into a cliff.
③Generate Beautiful Landscapes The plants make the landscapes more beautiful
④Hold CO2 in Plants or Underground CO₂
Plants take co2 into their bodies as resource of photosynthesis. The CO2 will stay with the plants if they wither.
⑨Generate Biological Energy
⑤Ecological Education
Eco systems would be energy hubs for example cleansing biotope, microbial power generation and microbial filtration system.
Green infra system is good place to study and to know how ecosystem works for
⑥Traditional Education
Landscapes with using original landforms and traditional landuse have almost goof influence.
⑦Green for Recreation
Lives with trees and flowers are good for mental health and stress reductions.
⑧Health Care
The increase in green spaces give people many opportunities for walking and cycling .
GI of stormwater management can be classfied to 6 functions. Relationships between them is illustrated below. a. Keep Leaves catch the waterdrops and hold them.
⑩Biotope for Creatures
Spreading green space means increase in biptope. It help the eco systems recovering.
b. Stay Plants suck rain water in through their roots.
⑪Precautions for Fire
The water rate in trees are depends on trees species. Using high water rate tree along the street works as a precautions of fire.
c. Retent The soil where plants live on is soft, so much stormwater.
⑫Place for Communication
Living with green infra increases opportunities to talk and co-operate with other person than living in grey infra.
e. Store Plants with pools or
d. Flow Stalks and roots help stormwater to flow slowlier.
basins help stormwater to turn into the vapor.
f. Clean 植物の根部分に住 む微生物などが手助 けをし、雨水が浄化 される。

a. KEEP
There is no plants with enough leaves to keep water
To correspond with climate changes and disasters, I combined green infra systems using traditional landuse and native lives and landforms. When green infra systems construct as one network, the effect would be stronger. To correspond the issues,main resource of green infra system is WATER. The minimum unit of water is a RIVER, so in this proposal, I choose Kanda river and designed three sites of Kanda river basin. And I propose these site for future 100 years. My vision for 100 years is the green infra network will be stronger, and ecosystems and human society get closer to each other again and when some areas get damages from disasters, this network would be resilience.

Progress is needed. The forest of Red pine trees are too simple as a landscape. and it does not have Green infra functions so much.
If f is needes, succession should be backed.
About a, it is needed on the cliff. because ever green trees have the leaves in all seasons.
If c is needed, ever trees should be cut frequently.
Control the stormwater to reduce the damage of the landslide. The fountain from the cliff shows stormwater flow that controled by this area s propsal
Middle Basin ー B.C.D
To reduce disasters from tidal waves or flood inland, make the band of swales along the Edo infra. The line will be a mark of the sea line in the future.
Downstream ー E
Moisten the Kanda River Basin Using Edo infrastructure Target area of upstream of Kanda river is the water source. By combining Edo infrastructure and water treatment plant, this area will work as a part of GI system. Now, the stage of vegetation transition is "Bare ground" here. By transforming the stage into the mixed forest evergreen and deciduous, the infiltration capacity of this area will be changed to high catchment. Infiltration at upstream can help water gush out again at Inokashira pond (the water source of Kanda river ).

Currently, Sakai water treatment plant and Tamagawa waterway is devided by the road. And the water level of Tamagawa waterway is low and there are a lot of plants that are not maintained.
⑶Separated Tanks at the Water Treatment Plant ■Purification System with Microbe
■Recycled Water
There is no connection with the water though Tamagawa Waterway is next to Sakai Water Treatment Plant. The water flowing in Tamagawa Waterway is a recycled water.
[Structure of Slow Sand Filter System]
The water system does not using the drug that has a carcinogenic risk, and the water has good taste. The slow sand filter system needs less consumption energy.
With classifying the map symbols in the old map(1909), strip shaped agricultural development can be seen. Strip shaped agricultural development was developed around Musashino plateau. At Musashino plateau, a surface layer is thick Kanto-Loam (volcanic ash). Under the surface, there is thick gravel layer. Because these 2 layers help water infiltrate, people could not get water easily around here. Then, the strip shaped development was done. The way of dividing land vertically is effective to supply land for people equally .

Making some of the plants with plant purification makes people who come to Tamagawa waterway come to the water treatment plant.
Breeze is so relaxing It s Japanese flower!
What s this?
By the plant succession progresses, this area becomes full of green. It will be used as a path that people walk along with dogs. Also it is used as a biotope that kids are able to learn nature, and a playground for kids.
I can enjoy birds singing.....
Nooooooo! I falled in mud!
Here is the space for the people IN the nature. While regular management, people enjoy their own activities here.
By the population decrease, people don t come here frequently. To continue picking weeds up and coppicing. The phase of the plant succession is kept at Mixed forest.
Manage and Visualize Stormwater
Use the Cliff terrain, to prevent the disasters, to visualize the flow of the water as a landscape design Mejirodai Sports Park
Target area of the middle basin is the valley and the cliff that was worn by Kanda river. First, control stormwater at C (Mejirodai Sports park) to prevent the outflow of rainwater into cliff and to prevent landslides. If the landslide would occur, new landscape would born. Also, visualizing water gushing can be an opportunity that people notice the system of the water management.

F-Role of Mangrove Fresh Water and Sea Water
F- Green Infra as an Educatinal Tool
F- Perspective Image F- 海面上昇時の効果
Making the educational facilities as cores of mangrove forest is not only for good infrastructure. This is also good for environmental education. Raising mangrove trees with kids makes that mangrove to be not only plants. this is also the sign of that coastline will come here. When people who raised up with mangrove trees become adults, they would tell their kids the meaning of mangrove forest. This would be new type of tools of environmental education that grey infrastructure have never done.
Mangrove can be useful for disaster by rain and sea
Coastline in the future
Mangrove live along the coastline. Mangrove forest would be a symbol of the future coastline.
Mangorve forest is expanding to the school ground
Roots of mangrove as a Filter
In the case the damage of high tide occurs, their roots would filter the sand flowing into the city

Educational facilities would be cores. Plant mangrove trees experimentally in school grounds.
Japanese alder forest start withering with sea water. Instead of them, mangrove trees would be planted. People who raise up with mangrove trees will become adults. When they have their children, tell them why mangrove trees are here.
Mangrove trees are raised by kids in classes and club activities
＝It would be a chance to know "why is the mangrove trees here?" Soil with the leaves of mangrove is rich of fertilizer. It would be good for creatures
Bank of CO2
GL -30cm
Mangrove forests keep 3 or 4 times CO₂ as many as CO2
Adults would join the project to extend the mangrove forest
Everyday kids see mangrove trees through their normal lives.
＝Kids would pay attention to sea level rise and water
Mangrove trees can be observed on the deck and under the deck.
After school, kids can enjoy playing with mangrove trees.

①Sea water is rising into land
①There are school ground and green space
①Storm water flow into school grounds
The bannd of mangrove is getting bigger.
②the band would be retarding basins.
①Raise the mangrove trees with kids

内水氾濫時、地形に沿い、 地側に水が流れ貯まる
There is a few super dikes here. This area is weak against water disaster because there are 3 rivers and sea.
The mangrove trees reared by kids at the school grounds would be big enough then. The adults who reared mangrove trees in their childhood and the kids transplant mangrove trees together.
If it is raining heavy, stormwater flows into the school grounds and Edo waterways with green infra. At the time of storm surge, the water flows into land with going up Sumida river.
F- Section Image (Flood) Block
When the advent of the super typhoon comes, the sea water will coming into the land from Sumida river by heavy rain and strong wind. Then the band with mangrove trees and school ground receive water. And mangrove trees take and hold salt.
When the sea level rises, the mangrove band that planned 100 years ago protect the coast line in the future. It means old infrastructures have potentials to use nowadays.

When it normal rains, rainwater come here from house block and here work as 遊水池
Plant mangrove trees experimentally along the school ground.When it's heavy raining, rainwater come into school ground.
To construct the school with raised floor style .The school ground would be sea.
Water Level (GL+1.0m)
When a super typhoon come or it's squall, the deck would sink. Instead of normal transportations people would use boats.
These deck made of dead Japanese alder wood. To make deck is for sea level rise.
IFLA Student Design Charrette 2018
03 「UNDERSTANDING MANGROVE DYNAMICS THROUGH LIVING MUSEUM」 I've joined IFLA Student Charrette 2018 in Singapore. The students are classified teams and each of them had theme Biophilia. Smart, Resilience. And we designed each site based on these theme.
01 What is IFLA Student Charrette 2018 ①Site and Theme
③Participates of this Charrette
02 Sungei Buloh Wetland Reserve
Students from 15 countries（Japan、Singapore、Thailand、Chili、Malaysia、France、 China、Honngkong、Indonesia、Australia、Columbia、Cameroon、USA）
03 Proposal「Understanding Mangrove Dinamics thorough a Living Museum」
"The Sungei Buloh Wetland Reserve ecosystem has two display modes composed by the interactions between water, flora, fauna and the visitor, but mainly produced by the seasonal change of tides. In the past the extent of mangrove forest was spread across all Singapore,but currently the mangrove forest is critically reduced. Our vision for the future is to create a green link of mangroves in the north side of Singapore as an adaptive proposal not only to conserve current wildlife but also to increase the biodiversity across the territory. improve the visitor experience and the ecosystem adaptation to new urban and global dynamics it is proposed a Living Museum through the development of a digital platform to interpret the ecosystem "

C U RAT OR I A L P R OP OS A L Under the objective of improve the visitor experience and the ecosystem adaptation to new urban and global dynamics it is proposed a Living Museum. The museography approach is developed though a digital platform to interpret the ecosystem when the visitor is into the landscape, providing a narrative of the place, a story-telling in real time.
