Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root brak. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment.
The Port of London Authority (PLA) is a self-funding public trust established on 31 March 1909 in accordance with the Port of London Act 1908 to govern the Port of London. Its responsibility extends over the Tideway of the River Thames and its continuation. It maintains and supervises navigation, and protects the river's environment.
The Thames Estuary is where the River Thames meets the waters of the North Sea, in the south-east of Great Britain.
Orford Ness is a cuspate foreland shingle spit on the Suffolk coast in Great Britain, linked to the mainland at Aldeburgh and stretching along the coast to Orford and down to North Weir Point, opposite Shingle Street. It is divided from the mainland by the River Alde, and was formed by longshore drift along the coast. The material of the spit comes from places further north, such as Dunwich. Near the middle point of its length, at the foreland point or 'Ness', once stood Orfordness Lighthouse, demolished in summer 2020 owing to the encroaching sea. In the name of the lighthouse, 'Orfordness' is written as one word.
The River Yar on the Isle of Wight, England, rises near the beach at Freshwater Bay, on the south coast, and flows only a few miles north to Yarmouth where it meets the Solent. Most of the river is a tidal estuary. Its headwaters have been truncated by erosion of the south coast.
The River Yar on the Isle of Wight, England, rises in a chalk coomb in St. Catherine's Down near Niton, close to the southern tip of the island. It flows across the Lower Cretaceous rocks of the eastern side of the island, through the gap in the central Upper Cretaceous chalk ridge of the Island at Yarbridge, then across the now drained Brading Haven to Bembridge Harbour in the northeast.
Miramichi Bay is an estuary located on the west coast of the Gulf of St. Lawrence in New Brunswick, at the mouth of the Miramichi River. Miramichi Bay is separated into the "inner bay" and the "outer bay", with the division being a line of uninhabited barrier islands which are continually reshaped by ocean storms. The largest of these islands is the uninhabited Portage Island, which was broken in two during a violent storm in the 1950s. The islands provide some protection to the inner bay from ocean storms in the Gulf of St. Lawrence.
The River Alde and River Ore form a river system in Suffolk, England passing by Snape and Aldeburgh. The River Alde and River Ore meet northwest of Blaxhall. From there downriver the combined river is known as the River Alde past Snape and Aldeburgh, and then again as the River Ore as it approaches Orford and flows by a shingle spit before emptying into the North Sea.

Havergate Island is the only island in the county of Suffolk, England. It is found at the confluence of the River Ore and the Butley River near the village of Orford. It is a marshy nature reserve run by the Royal Society for the Protection of Birds (RSPB) and is known for its population of pied avocets and terns. It is part of the ecologically important Alde-Ore Estuary and has protected conservation status as part of a national nature reserve, SSSI, SAC, SPA, Ramsar Site and is also a part of the Suffolk Coast and Heaths AONB.
The Lydney Canal is a one-mile canal in Gloucestershire that runs inland from the River Severn to Lydney. It was opened in 1813 to trans-ship iron and coal from the Forest of Dean. It was once connected by a horse-drawn tramroad to Pidcock's Canal which brought materials down to the wharves by tub-boat.
This is a list of the longest rivers of the United Kingdom.

The coastal part of the site is Orfordness-Havergate, a National Nature Reserve, and Orford Ness is managed by the National Trust, while Havergate Island is managed by the Royal Society for the Protection of Birds.
Alde Mudflats is a 22 hectare nature reserve west of Iken in Suffolk. It is owned by the Crown Estate and managed by the Suffolk Wildlife Trust. It is in the Suffolk Coast and Heaths Area of Outstanding Natural Beauty, and part of the Alde-Ore Estuary Site of Special Scientific Interest, Ramsar internationally important wetland site, Special Area of Conservation, Special Protection Area under the European Union Directive on the Conservation of Wild Birds, and Grade I Nature Conservation Review site,
Simpson's Saltings is a 25 hectare nature reserve on the Suffolk coast east of Hollesley. It is managed by the Suffolk Wildlife Trust. It is in the Suffolk Coast and Heaths Area of Outstanding Natural Beauty, and part of the Alde-Ore Estuary Site of Special Scientific Interest, Ramsar internationally important wetland site, Special Area of Conservation, Special Protection Area under the European Union Directive on the Conservation of Wild Birds, and Grade I Nature Conservation Review site,
Hazlewood Marshes is a 64 hectare nature reserve west of Aldeburgh in Suffolk. It is managed by the Suffolk Wildlife Trust. It is in the Alde-Ore Estuary biological Site of Special Scientific Interest.
Nanaimo Harbour, also known as the Port of Nanaimo, is a natural harbour on the east coast of Vancouver Island in the Canadian province of British Columbia. The city of Nanaimo runs along the west side of the harbour. Three islands, Newcastle, Protection, and Gabriola, along with Duke Point, form the eastern edge. The Port of Nanaimo includes the Inner Harbour, Nanaimo River estuary, Departure Bay, the waters on the east side of Newcastle and Protection Islands, and Northumberland Channel. The port is under the management of the Nanaimo Port Authority.
Powerline river crossings comprise both overhead lines and cable tunnels beneath rivers and estuaries. Overhead power lines are supported on towers which are usually significantly taller than overland pylons and are more widely spaced to cross the river in a single span. Tall pylons ensure that the electricity cables which they support provide an adequate safety clearance for river traffic.
