spanning across the Murrumbidgee River located near Gundagai. Through the use of hydrological data and hydraulic analysis we will determine the required height of the bridge corresponding to a specific frequency of flood. To design a bridge capable of spanning the Murrumbidgee River and flood plain will require hydrological analysis which takes into account all upstream data that is required for the catchment area of the river that will pass Gundagai. Once the hydrological data has been found we can

Does river engineering have the potential to make floods worse? This essay will involve explaining whether or not different types of hard and soft engineering make floods worse. I will go through each type of engineering and explain their advantages and disadvantages to see if they are each capable of making a flood worse or not. Levees Levees are an example of hard engineering and are basically just big piles of either concrete‚ rocks or soil that have been piled up to increase the height of
