The London Borough of Camden is situated on the northern side of the City of London within the Ceremonial county of Greater London. Being the capital of United Kingdom, London is the most developed region of the country. It comprises an area of 609 square miles or 1,579 square km and lies besides the River Thames. Thames is a navigable river, therefore giving London the status of a port. The expansion of the city mainly started on the northern part of the river and continued. For many years, London Bridge was the only connecting point to the other parts of the town. After 18th century the city started expanding in all directions.
The River Thames is by far the largest river of the London area. River Thames and its tributaries which is the lifeline of London flow from west to east across the London Basin. In spite of constantly being the largest river in London, over the time it has choked up due to the considerable city expansion. A number of rivers and streams flow into Thames, which has had a significant influence on London’s geography. But due to infrastructure build up, most of the tributaries now flow underground.
Most of London lies within the bowl of London Basin, while a small part of it, especially Southern London lies on the back slope of the North Downs. The valley of River Thames forms the centre part of the basin, running from east to west. The modern floodplain of Greater London lies half a mile to the west and two miles wide to the east. Certain importance terraces run for miles from the floodplain such as in Hounslow and Southwark. Other noteworthy valleys and floodplains include those of Colne, Crane, Brent, Lea, Wandle and Ravensbourne running north and south of Thames. Some of these floodplains are more than mile wide in some places.
London experiences a temperate nautical climate throughout the year with no extreme changes in the temperature. While the summers are warm, winters are cold, but not freezing. Spring is the most favorite season with Londoners experiencing an atmosphere of mild sunlight and cool evenings. Temperatures during the summer season range between 23 °C to 14 °C, while in winters it can get cold as 2 °C to 8 °C.
