Impact of Floods

An additional difficulty facing the colonial engineers arose from the lack of adequate information on extreme floods. Unable even to adopt the time-worn rule of thumb that set the maximum flood at the level of the ferryman's doorstep, they were required to extend their judgment into the realms of guesswork. Thus, for instance, the Albert Street Railway Bridge in Brisbane, built in 1875 with a clearance of 30 feet above the highest known flood, was washed away a mere eighteen years later. Floodwaters rose close to the girders, carrying large masses of debris (including numerous houses and other buildings) and scoured the river bed to a depth of 40 feet. Time was to show that such violent floods were characteristic of many Queensland rivers, and that deep and strong foundations were essential.
