Shibitachi September 2014

Shibitachi September 2014

In September 2014, I was happy to see Shibitachi still without a seawall. However, it could become a reality soon. The process is not very clear for an otsider, but from what is documented here:

I can gather that a 8.1m tall wall is still planned for Shibitachi.

I did some models to see if: 1 the wall would actually protect anything and 2 what impact it would have in a lower height.

Seawall model TP 8.1

This is the model of a 8.1m high seawall based on the drawings and topographic information available here:

In the drawing it seems like that one or two buildings would be ‘protected’ by the new infrastructure. All other buildings are either destroyed or located on higher ground.

Inundation model major

The first model of inundation is illustrating that if a major Tsunami hits, the wall will be submerged. The wall is designed for smaller, more frequent Tsunamis.

Even if a smaller wave is generated, it is likely that the area behind the wall will be inundated as shown in this model.

Finally noting, that no buildings would be protected as there are none to begin with. Further, the wall has a very wide base of up to 30m, meaning it would actually cover all area for buildings.

Note: the inundation models were created based on information accessed here:

RMIT Design Research Studio After Landscape II

In June 2014 a group of RMIT Landscape Architecture and Architecture students traveled to Tokyo and Tohoku to investigate the status of rebuilding in Kesennuma, Rikuzentakada and Koizumi.

The specific task of the studio included:

Developing a methodological design toolkit through spatial, practice and consultant research and applied design.

Describing a site through its parameters, both abstract and concrete, to inform design outcome.

Working through an informed logic of translation and abstraction of ideas.

Engaging critically with notions of the other to reflect on own situations and practices.

The work was exhibited in Tokyo and Melbourne.
