Erosion is usually a slow and gradual process that takes thousands or even millions of years. But man's activities such a farming, boating, and urban development can speed up the erosion process.

This is also the spot where boats from the Thames and Severn canal
join the river on the right.

The house, in the photograph above, marks the end of the navigable part of the River Thames. The river continues on in front of the house and to the left.

Erosion caused by boats

The erosion in the photograph above, could have been the result of boats turning around because they can not go any further up the river.

The wash from boats crashes into the banks.
