U.S. civil and maritime uses of tidal data. A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1]
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]
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.

Water level, also known as gauge height or stage, is the elevation of the free surface of a sea, stream, lake or reservoir relative to a specified vertical datum. [1]
European Union of Water Management Associations (EUWMA) members are (umbrella) organizations in the EU member states representing organizations based on public law responsible for regional and local water management (flood protection, land drainage, water level management, irrigation) such as internal drainage boards or Waterschappen.
European Union (EU) concepts, acronyms, and jargon are a terminology set that has developed as a form of shorthand, to quickly express a (formal) EU process, an (informal) institutional working practice, or an EU body, function or decision, and which is commonly understood among EU officials or external people who regularly deal with EU institutions.
The European Union needs to make extra investments of €90 billion in the water and waste sector to meet its 2030 climate and energy goals. However, wastewater resources can be useful. In the European Union, an estimated 60–70% of wastewater's potential value is still untapped (in heat, energy, nutrients, minerals, metals, chemicals). [10 ...
The European Atomic Energy Community (EAEC or Euratom) is an international organisation established by the Euratom Treaty on 25 March 1957 with the original purpose of creating a specialist market for nuclear power in Europe, by developing nuclear energy and distributing it to its member states while selling the surplus to non-member states.
