Water phenomenon of urban morphology
Assemblage urban elements: Building footprints
The built environment alters the natural flow of rainwater as shown in the Russell Street Transect, demonstrating its adaptation to urban morphology. As one stream goes into another, the grade rises, meaning that the higher the grade the more intense the flow will be. This is illustrated in the “Grade of Water Flow” map.
Contour lines (interval of 5m) Drainpipes
Grade of water flow: Grade 1
Furthermore, topology and slope gradient are factors that highly influence the direction and flow of rainwater, forcing it to flow from the north-eastern peak of the city down the slope towards the Yarra river.
Where are the most impermeable surfaces?
Grade 2 Grade 3 Grade 4
Steepness of Slope (in approximate degrees):
This exercise has identified the transect’s pervious and impervious surfaces by analyzing the existing surrounding stormwater drainage network. As a result, the city contains a more integrated drainage network as opposed to areas outside the city.

This is significant since the increased built form affects the perviousness of the surface, which needs better drainage system to drain rainwater. However, the transect’s top areas of open green spaces, such as Lincoln Square and Argyle Square, act as a catchment to compensate the surrounding area’s impermeability. Therefore, a less integrated drainage network is needed and by mapping this, we are able to plan for a better water management in the transect.

ADAPTATION
Analysis: The urban form of barcelona Barcelona have retain its urban organic form due to the construction of its city walls during the middle ages. However, in 1859, when the Spanish urban planner, Ildefons Cerda’s city expansion plan was approved, the urban development was planned using an extensive grid-iron pattern. Trends in urban planning have changed over time from free form to a grid-like system and it becomes a present challenge to connect the past and present.

So why Georgetown?
Carnarvon Street
Georgetown, the capital city of Penang, Malaysia, is recognized as one of the UNESCO’s World Heritage Sites since 2008. The city itself has an organic and loosely planned urban grid form that comprises notable architectural styles, diversity and cultural influences.

Interesting and diverse sections, such as the laneways and curving streets within the urban form of Georgetown have been captured and mapped into the Russell Street Transect. As a result, they are placed within areas of impermeability and uniform functions within the transect. The juxtaposition between these two distinguishable urban morphologies pushes the boundaries of the transect’s laneways, diversity and form in terms of its pedestrian experience as well as the reclamation of urban space.
