To feet of water can lift and Cary a car or bus down stream?

Generally, it takes about 2 feet of water to lift and carry a small car downstream, while a larger vehicle like a bus may require at least 3 to 4 feet of water. The force of the current, along with the vehicle's weight and buoyancy, plays a crucial role in determining whether it can be moved. Additionally, factors such as water density, debris, and the slope of the riverbed can also impact the ability of water to transport vehicles.
