Story Bridge, Brisbane, Australia
Brisbane, capital of Queensland, is a large city on the Brisbane River. The Brisbane river, runs through the CBD of Brisbane, forms a U turn in between Kangaroo point and Fortitude Valley. A famous tourist hot point with the Story bridge connecting the two area. The Story Bridge is a heritage-listed steel cantilever bridge spanning the Brisbane River that carries vehicular, bicycle and pedestrian traffic between the northern and the southern suburbs of Brisbane, Queensland, Australia. It is the longest cantilever bridge in Australia.
Site Topography
The topography section shows that the site is mostly stable in elevation. The river is slightly lower than the shore side, ensuring less flooding opportunity. A tidy, flat site allows an ordered city layout since no compromise has to be made elevation wise.

Flooding and Tide
For the vast majority of the time, they operate as estuaries, with salt water extending far up into the river reaches and the freshwater and salty water mixture sloshing back and forth with the tides.
The river flows year round and modelled mean annual flow for the entire basin is 1751 GL (NLWRA, 2001). It has a 2-2.5m rise and fall creating a tidal flow of 2-4 knots (4-8km/h).
By its very nature, the Brisbane River is brown because it's an estuary and influenced by the tide. Water flows from the catchment upstream, bringing sediment with it and as the tide comes in from the opposite direction, it causes a lot of turbulence in the water, continually stirring up the sediment.

Busy city like Brisbane would normally have bad traffic, yet Brisbane has an advantage to diffuse the traffic load. Therefore, traffic on a Monday morning would not be too bad.

Fortitude Valley Story Bridge Residential Area
Urban Plannin This area contains multiple functions, commercial, site seeing and residential. All the function areas are rationally united by convenient transportation. The area might seem clustered, yet the arrangement is rational in use.

Summer in this area has longer daytime compared to winter times. Due to the relatively short architectures, and flat topography, little shadings are created, thus the whole site has sufficient sunlight all year round.

Brisbane has four main soil types: dark alluvial soils. deep red loamy soils. gravelly red and yellow loamy top soils over clay. Fortitude Valley and Kangaroo Point's soil are mainly shallow gravelly soils.
The site has plenty city greening. Despite the drought situation in most Australian land, Brisbane has a relatively moist weather due to the costal location and the large river running through city central. Therefore, floral resourses here are rich in species and quantity, the city botanic garden especially.

Due to file size limitation on SketchFab, only the Story bridge area was kept. The cropped area was selected due to its rich information on buildings, transportation (bridge and piers), vegetation, as well as flooding.
