Describe and analyse the biophysical interactions that impact on the Madden’s Creek ecosystem. The Madden’s Creek ecosystem is located at the beginning of George’s River and is found 60km south west of Sydney at an elevation of 350 meters above sea level. About 45% of the catchment contains large tracts of natural bush land. It is home to many species of flora and fauna creating a wide range of biodiversity that interlink and affect each other significantly. In this ecosystem there is a mixture

There was a pontoon bridge across the river and carts‚ trucks‚ and men‚ women and children were crossing it.

Truss bridges are recognizable because of their numerous‚ relatively small interconnected triangles. This framework of triangles is used for is strength to withstand tension and compression forces. They are considered a light-weight yet a very stiff form of construction. At first they were built of wood‚ then with the discovery of welding they began to build then using iron‚ then steel. Occasionally‚ a combination of the materials may be used. There are actually 30 different kinds of truss bridges
