The River Thames has numerous industry and urban areas along its length raising interest among researchers, industry and the environmental regulatory community.

The River Thames is a river that flows through southern England. With a total length of 346 km (215 miles), it is the longest river entirely in England and the second longest in the United Kingdom, after the River Severn. While it is best known for flowing through London, the river also flows alongside other towns and cities, including Oxford, Reading, Henley-on-Thames and Windsor. In an alternative name, derived from its long tidal reach up to Teddington Lock in south west London, the lower reaches of the river are called the Tideway. The section of the river running through Oxford is traditionally called the Isis (Wikipedia).
