THE MEDIATOR BOSTON HARBOR RESERVED CHANNEL DESIGN

Time: Sep.2016~Nov.2016 GSD 1211 studio: The Adaptive City Nominated for GSD Platform10 Location: Reserved Channel, South Boston, MA, US Tutor: Sergio Loez-pineiro Type: academic Size:33.5 Ha Collaborator: Matthew Wong

Boston harbor, serves as the main port of Boston. It is a good example of global harbor area. For the maintaining of shipping channel, the dredge operation happens regularly. At the same time, a coastal city has to face the rising sea level. This program use Boston harbor as a model to explore the strategies for coastal cities to deal will both sea level rising and dredge operation and also change of rainfall.

We design a landform system in a long time process, which will develop with the city. Dredge materials are used to build new landform after phytoremediation process and protect city from the rising sea level. At the same time, another landform collects and purifies rainwater to build a wetland area between urban areas.

The program deals with four changes to urban area: - Rising sea level, - Change of rain fall - Increased dredge material - Population growth

GENEALOGICAL TREE Starting with landforms, this program combine different landforms and make connection between dredge material and seawater.

DESIGN STRATEGY

PROCESS

Construction period

Dredge material will be used to build dike, some programs begin to appear. Plants are used to do phytoremediation.

Nursery and wetland appear, more programs happen.

Soil test starts on where dredge material placed.

Urban construction begin to expand, some nursery area and wetland area are replaced. Construction of dike and phytoremediation process continue.

Urban area continue to expand. Buildings begin to show on the earliest dike area. More nursery area and wetland area will be replaced by urban area.

Urban construction and soil phytoremediation are still in processing. The dredge operation happens again for the maintaining of shipping channel.

Buildings expand to more area, no nursery area anymore, trees in nursery are used as street trees

Construction continue, but the expansion of building stop at the edge of the wetland. The middle area is left for eco-park

Urban construction comes to end, more programs happen on the water.

upstream Because of Cuba’s Large-scale, over engineered dams cause more problems than benefits for the region and its economy, we propose to stop dam maintenance, accepting their expected 50-year lifespans. We propose upstream shifting from impermeable dams and open, standing reservoirs, to a system of smaller, softly-engineered micro-dams that allow for downstream flow, and place water management into the hands of local agricultural stakeholders.

The presence of the military base and its historical and political complexities, as well as the highly engineered and industrialized waBelinda Tato ter management and infrastructural development in the region have led to the suppression of the ecological processes and hindered both the metabolism of the watershed and potential economic activities for the local communities. These conditions along with contaminated effluents deforestation, erosion of soils, salinization of aquifers and climatic changes have contributed to an ongoing process of desertification of the watershed.

We understand this landscape as a hydrosocial territory: “socially, naturally and politically constituted spaces that are (re)created through the interactions amongst human practices, water flows, hydraulic technologies, biophysical elements, socio-economic structures and cultural-political institutions”. Our project redefines the territory through this notion by empowering the watershed to enhance the region’s autonomy. Though a series of landform operations, water retention and flow soft systems and using plant agency we will slow the flow of water, increasing the holding capacity of the arid soils and fortifying the watershed against looming climate change effects. These bottom up strategies bring power back to the communities, promote self sufficiency and reinforce existing local economies.

Existing salt pans lie on flood plain elevation, which is precarious for salt industry as well as groundwater reserves. Berms and terracing will protect fields.

Accretion layer stabilized by soft engineering and vegetation

Dense, fast-growing land builders thriving in brackish marshes. Sediment accretion protects coast from sea level rise Initial Soil Accumulation and buffers salt fields.

Buffers salt fields and freshwater from storm surges, remediates upstream pollutants, and is home to many species of plants that grows easily in salty and alkaline soils.

Lives directly on the water, sheds excess salt, grows out of the muddy alluvial deposits.

THE STORY TELLER AMTHITHEATER DESIGN

Time: Apr.2016~May.2016 Location: Changde, Huan Province, China Tutor: Dongyun Liu Type: academic Size: 0.7 Ha

This project is a amphitheater near an old moat. It locates in a new business area where used to be an historical old city. This design combines the old city’s element with modern urban use. Old bricks are used to build the new theater, folding line is used to represents the turbulent history of this site and create a various experience at the same time. At night, the light design is try to create a feeling of “light from an ancient city�.

SHE IS THE ONE WHO FIND THAT SILKWROM CAN PRODUCE SILK AND USED IT TO SPIN FOR CLOTH. IT IS HER CREATED THE SILK AND THE SILK CULTUREOF CHINA BEGAN. ACCORDING TO HISTORICAL RECORDS, JUST BECAUSE OF THE CREATING OF SILK, CAN ACIENT CHINESE PEOPLE SURVIVED FROM THE HOSTILE ENVIRONMENT AT THAT TIME. WITH OUT SILK, THE CIVILIZATION OF CHINA TODAY MAY NOT EXIST. BUT FEW PEOPLE KNOW ABOUT THE CREATOR OF SILK.
