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 ...
The New York State Department of Environmental Conservation has created an Accessible Recreation Destinations Map for over 200 ADA accessible education centers, campgrounds and day use areas ...
The reference water levels are used on inland waterways to define a range of water levels allowing the full use of the waterway for navigation. [1] Ship passage can be limited by the water levels that are too low, when the fairway might become too shallow for large ("target", "design") ships, or too high, when it might become impossible for the target ships to pass under the bridges.

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
Water level elevation in the lake is maintained at a maximum of 280 feet (85 m) above sea level, 35 feet (11 m) lower than the dam's maximum of 315 feet (96 m) spillway to ensure safe operations. [3] The lake level can fluctuate significantly, depending upon the amount of runoff received from the San Dieguito River drainage basin. [ 4 ]
