The Association of Drainage Authorities (ADA) is a membership body for internal drainage boards and other stakeholders in water level management in the United Kingdom.. ADA obtains and disseminates information on matters of importance and interest to members, and provides assistance on technical and administrative problems.
In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. [3] Bathymetry has various uses including the production of bathymetric charts to guide vessels and identify underwater hazards, the study of marine life near the floor of water bodies , coastline analysis and ocean dynamics , including ...
Map of the Earth with a long-term 6-metre (20 ft) sea level rise represented in red (uniform distribution, actual sea level rise will vary regionally and local adaptation measures will also have an effect on local sea levels). After 500 years, sea level rise from thermal expansion alone may have reached only half of its eventual level - likely ...
Between 1873 and 1874, he had daily measurements taken of the water level of the adjacent sea arm, Het IJ, during high tide. The calculated averaged was called the Amsterdams Peil ("Amsterdam level", AP) and used to calculate the minimum height of the sea dykes, which he set at "9 feet and 5 inches" (2.67 m) above AP. [2]

Tunnel datum is a datum based on an ordnance datum and used in designing tunnels which pass below sea level. for the London Underground, a tunnel datum of ODN −100 m is used; [7] thus a depth of −60 m AOD is 40 m ATD (above tunnel datum) for the Channel Tunnel, a tunnel datum of ODN −200 m is used; [8] thus a depth of −60 m is 140 m ATD
