Is the River Lea a typical river?

No, the River Lea is not a typical river. It is a relatively small river, with a length of only 69 miles. It is also fairly shallow, with an average depth of only 1.5 meters. Additionally, the River Lea is heavily urbanised, with much of its course flowing through the suburbs of London. This has resulted in the river being polluted and its natural habitats being disrupted. As such, the River Lea is not a typical example of a river.
