WHAT IF
Anchor a as top-down operation can trigger bottom-up landscape transformation in Yutum Alluvial Fan?

]

STATEMENT

FAN URBANISM aims to generate a responsive landscape in alluvial fans along Wadi Arabah that coexists with urban settlements. The proposed adaptive system utilizes stormwater and sediment as a productive asset and emerges to a nodal network. 

Starting with a top-down operation, stormwater will be reclaimed by decommissioning existing water channel. As water flows back into the alluvial fan, the testing anchor will be planted accordingly to collect water and sediment as well as to rebuild natural habitat, experimenting soil fertility and water catchment at these points. At locations with more resource accumulation, anchors can be rebuilt as infrastructure units that allow for transportation and utility connection. These infrastructure anchors can expand as a nodal network, collecting and sharing resources such as water and solar energy that sets up the ground for future urbanization. In this way, anchor as the top-down operation can trigger bottom-up landscape transformation in Yutum Alluvial Fan, which would also become a replicable inhabitation strategy that could apply to the alluvial fans in the region.

#4 NEW DEVELOPMENT IN THE FAN

In the future

Massive New Development in North Aqaba are all in the most vulnerable regions for Flashflood hazards

#3 GOVERNMENT SOLUTION

After 2006
