River Darent

The Mardyke (sometimes, but less frequently, Mar Dyke, occasionally Mardike) is a small river, mainly in Thurrock, that flows into the River Thames at Purfleet, close to the Queen Elizabeth II Bridge. In part, it forms the boundary between the Essex hundreds of Barstable and Chafford. The river gives its name to the Mardyke Valley—a project aimed at increasing appreciation and usage of recreational land around the Mardyke.

Rainham Marshes is an RSPB nature reserve in the east of London, adjacent to the Thames Estuary in Purfleet, Thurrock and the London Borough of Havering. In 2000, the area of land was bought from the Ministry of Defence, who used it as a test firing range. With no activity for several years, the nature reserve was officially opened to the public in 2006. It has maintained much of its medieval landscape, and is the largest area of wetland on the upper parts of the Thames Estuary. The reserve is home to a diverse range of bird species, wetland plants and insects. It also has one of the densest water vole populations in the country. In December 2005, the site was visited by a sociable lapwing; over 1,700 people visited the reserve to see this bird. Late in the bird's stay, four penduline tits were also found at the site. Entrance to the site is free to residents of Thurrock and the London Borough of Havering.The site is home to an environmentally friendly visitor centre which features solar panels, rainwater harvesting, natural light and ventilation and a ground heat exchange system. This visitor centre, completed in 2006 at a cost £2 million, was designed by van Heyningen and Haward Architects The building won six awards for its BREEAM sustainable design, including a Green Apple Award, Regeneration and Renewal Award and a Royal Institute of British Architects National Award.The site is part (77% according to a BBC article) of a Site of Special Scientific Interest (SSSI) called Inner Thames Marshes, and the part which is in the London Borough of Havering has been designated by the council as a Site of Metropolitan Importance for Nature Conservation called Wennington, Aveley and Rainham Marshes. The area west of a drain running south from Brookway is a Local Nature Reserve (LNR), as well as being part of the SSSI. South of the A13 road the LNR is part of the RSPB reserve, while the northern part is managed by Havering Council. Before the site was protected as a nature reserve, it was considered as a candidate location for a Universal theme park in the 1990s, but a site in Paris was eventually chosen. This project failed to materialize

The River Cray is the largest tributary of the Darent. It is the prime river of outer, south-east Greater London, rising in Priory Gardens, Orpington, where rainwater percolates through the chalk bedrock of the Downs to form a pond where the eroded ground elevation gives way to impermeable clay. Initially it flows true to form northwards, past industrial and residential St Mary Cray, through St Paul's Cray (where it once powered a paper mill) and through Foots Cray, where it enters the parkland Foots Cray Meadows, flowing under by Five Arches bridge (built in 1781 as part of their designs by Capability Brown). It then flows by restored Loring Hall (c.1760), home of the Lord Castlereagh who killed himself there in 1822. It continues through North Cray and Bexley. It neighbours a restored Gothic (architecture) cold plunge bath house, built around 1766 as part of Vale Mascal Estate. It is then joined by the River Shuttle (a small brook) and then continues through the parkland of Hall Place, which was built for John Champneys in 1540. The Cray turns eastward through Crayford and Barnes Cray to join the Darent in Dartford Creek. The Creek is a well-watered partly tidal inlet (of the Tideway) between Crayford Marshes and Dartford Marshes by a slight projection of land, Crayford Ness. The villages through which the Cray flows are collectively known as "The Crays".

It is described by Natural England as a "site of national importance for the study of Quaternary environments and climates".There is access to the site from Purfleet Road, but no geology is visible as the excavations have been filled in.
