DESIGN AMBITION
SCULPTING FLOW
DESIGN PROCESS
THE AMBITION OF SCULPTING CREEKSCAPE IS TO 1 - REACTIVATE THE INTERACTION BETWEEN THE CREEK AND ITS FLOODPLAIN (LANDFORM AND WATER) THROUGH A SITE-SCALE WATER STRATEGY, ULTIMATELY GENERATE SELF-MAINTAINED SCHEME FOR SEASONAL FLUX OF THE CHANNEL
SCULPTING GROUND
POOL-RIFFLE : SELF-SUSTAINED CREEK MORPHOLOGY The inspiration to test micro-lanform is to address WSUD principle, which emphasizes decentralized stormwater detention infrastructure. Hence, pattern for riparian landform is selected due to the flow accumulation that faciliate floodplain capacity to ‘detend’ water locally in a micro-scale, improving local water infiltration.
Riffle pool sequence: Design considers heterogenity in stream cross-sectional morphology to create structurally hetetogenous streambed which help retain water on-site, create suitable habitat for different species and rely on self-maintained machanism.

PRECIPITATION
With the installation of undulated micro-landform, the infiltration of stormwater has been improved through temporary detention in series of ‘valleys’. This source of infiltrated water is used to cultivate nearby trees and vegetation. The landscape in its complete state as shown in final phase is structurally complex, with under-storey and over-storey habitat, providing nesting, breeding and migrating environment for birds and other terrestrial species.

Riffle pool sequence: While the possibility of re-meandering creek is limited due to rigid buffer zone, the design considers heterogeneity in stream cross-sectional morphology to reflect natural channel with series of riffles and ponds (upon which the creek is name after in aboriginal language: Moonee Moonee Chain of ponds).
Reactivating interaction between ground water and surface water, which ultimate goal is to reconnect stream with its floodplain. This will become premise for future flood resilience.
Extend the benefit of this rehabilitation project to a wider landscape by creating stepping stones for aquatic and terrestrial species. This is achieved by series of ponds as migrating habitat for amphibians, and regenerating green corridor for bird movement.

Riffle and pool are again restored to achieve the general goal of retain water and respond to flux. This sequence of pool and riffle, however, is intensified in depth because of the natural force generated by existing topography.

Landform is generated by force. This phenomenon can be widely observed in our natural environment: tectonic movement in volcanic landform; wind in the case of sand dunes or water flow in fluvial floodplain. Hence, the design elaborates on the idea that force influences the terrain landscape, in the way that can be broken down into parameters to reversely re-construct the desired topography utilizing digital platform. Sculpting creekscape seeks to explore this notion of force in the form of water flow, in order to generate an adaptive scheme to flux in the context of Moonee Ponds Creek .
