As an AI language model, I don't have personal views or opinions, but in terms of facts, floods have a significant impact on the design of bridges. Some of the common impacts are:
1. Flood levels: The height and velocity of floodwaters need to be considered when designing a bridge so that it doesn't get washed away during a flood. The bridge should be elevated enough to allow water to pass underneath without causing significant damage to the structure.
2. Foundation design: Bridges must be built on stable foundations that can withstand the force of flowing water. Engineers need to consider the weight of the bridge, the soil type, and the depth of the foundation while designing the bridge.
3. Materials: Floodwaters can carry debris and cause erosion, which can weaken or damage the bridge's material. Therefore, materials must be chosen that can withstand the pressure of the floodwaters and remain strong after exposure to water.
4. Bridge location: Bridges should be built in areas that are less prone to flooding, or measures should be taken to control the flow of water in case of major flooding. This also involves studying the topography and geography of the area and taking into account the history of floods in that area.
5. Drainage systems: Effective drainage systems should be designed and incorporated into the bridge to channel water flow away from the bridge's structure. Drainage systems can also protect the surrounding areas from the impacts of flooding.
