A civil engineering firm has been contracted to design and construct a steel bridge over a river in a remote region of Australia. The site is located in an area with rugged terrain, and the river is prone to flooding during the wet season. The client has requested that the bridge be designed to withstand the worst-case scenario flood conditions, and the project team must evaluate potential site hazards, constraints, and conditions to ensure the safety and success of the project. Briefly explain the different techniques that the project team can use to evaluate potential site hazards, constraints, and conditions. (100-150 words)
