2. SAKUTEI-KI Thashibana no Toshitsuna (Garden of stone)

3. 1° Sakutei-ki (Notes on garden fabrics -fabricating gardens or garden manufacturing ?) authored by Tachibana no Toshitsuna (aristocrat of the imperial court, XI century) . His master the esoteric boudhist monk ( † 1040) En' in ajari taught the secret technic that was going to be an art. 2° Firstly accepted as chinese technics, Tachibana then rejected them to make its own Sakutei-ki (perhaps the oldest known book on fabricating gardens) 3°Sakutei-ki a) guide lines are: -> stone orientations -> stone shaping and -> stone setting- ups b) in relationships with the: -> river courses -> lake bends -> waterfall drop points -> games of spread sizes -> games of proportion sizes -> energies c) which goal is to: -> deepen the viewer imaginary -> confond reality with a paralleled

4. 2 versions of the book: +Orale Professor Masuda taught to foreign students in Kyoto University the Sakutei-ki in 1963 +Detailed version by Michel Vieillard-Baron help to catch-up forgotten aspects and rules often neglected

5. Also, Sakutei-ki is very appropriate to a zen attitude . In fact, what emergency rescue and disaster management are offering for salvation to people at risk of flood is a project management, where the risk reduction would be to late, with: -> unsustainable walls (to stop flood) -> unsustainable sand bags -> salvaging the environment including the initial urbanism -> run-aways and exit routes in term of emergency evacuations -> planning that considering water as a foe -> development for rescuer organizations and little left for the sufferers Myviewpoint is to reverse the trend of adversity condtions that are stressfull by and a zen attitude, where people are unable to be worried too much about the water rising dangerously because of the Sakutei-ki or new flood architecture (with trees and stones that are permanent settlement (and not mobile).

6. The Sakutei-ki which is issued from ancestral chinese art of fabricating gardens with stone has been passed to posterity of art history by Tachibana (from the teaching of his master budhist monk En' in ajari) and as most ancien technologies or arts, it has been forgatten but I found it fits well for future flood development mitigations or adaptation strategies, whithin the flood urbanism. Anyway in my project , properly layout of stones in water for screening flood flows or building in elevation like piloti house is paramount before all industries takes place (we have the example ofthe city of Venitio, which is over 500 years settled on water) . In addition , as the Sakutei-ki guidelines are stimulating an open door to the real world into paralleled worlds of garden, it helps to relief psychology energies from people at risk of flood during the occurence. Building gardens with stones (including planting trees) for safety of dry feet zones and sufferer sheltering participates in flood risk reduction and post recovery operation. So, the WAER project is a mix of combined communication technologies (mobile phone camera, GPS, internet...sensors) and innovative operations (use of drones to drop water purifiers) and the natural environment, which needs to be reorganized in inundated zones where the likelyhood of flood risks can have severe impacts on people lives and their properties.
