Where are flood plains of the river Thames?

Flood plains of the river Thames are located in England, specifically in the southern and eastern parts of the country. They stretch along the river's course from its source in the Cotswold Hills to its mouth at the North Sea. The flood plains are formed by the sediment deposited by the river over thousands of years and are typically low-lying areas adjacent to the river channel. These areas are prone to flooding during periods of heavy rainfall or when the river overflows its banks, resulting in the inundation of surrounding land.
