Thames Walk

I write about River Thames. The river is running in South England. The length is 346 km. River Thames  was polluted by sewage or industrial wastewater in 19th century. But now, it become to clean because of different cleaning projects. In England many places have "ford" in their names. For example, we know Oxford and Stafford. The "Ford" means the shallow place in the river or lake. People crossed River Thames by walking on the ford when they had no bridges. From this background, people gather near the ford and it became the big city.
