FAN URBANISM aims to generate a responsive landscape in alluvial fans along Wadi Arabah that coexists with urban settlement. The proposed adaptive system utilizes stormwater and sediment as a productive asset and emerges to a nodal network. Starting with top-down operation, stormwater will be reclaimed by decommissioning existing water channel. As water flows back into the alluvial fan, 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 top-down operation can trigger bottom-up landscape transformation in Yutum Alluvial Fan.
