How deep can a flood go?

The depth of a flood can vary significantly depending on factors such as terrain, rainfall intensity, and existing water levels. In extreme cases, floods can reach depths of several feet, with flash floods potentially exceeding 10 feet in urban areas and rivers overflowing their banks. Coastal and tidal floods can also inundate low-lying areas to substantial depths. Ultimately, the specific depth of a flood can vary widely based on local conditions and circumstances.
