Vodyanoy by Ivan Bilibin, 1934. In Slavic mythology, vodyanoy (Russian: водяной, IPA: [vədʲɪˈnoj]; lit. '[he] from the water' or 'watery') is a water spirit.In Czech and Slovak fairy tales, he is called vodník (or in Germanized form: Hastrman), and often referred to as Wassermann in German sources.
The above groundwater flow equations are valid for three dimensional flow. In unconfined aquifers, the solution to the 3D form of the equation is complicated by the presence of a free surface water table boundary condition: in addition to solving for the spatial distribution of heads, the location of this surface is also an unknown. This is a ...
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
This equation and notation works in much the same way as the temperature equation. This equation describes the motion of water from one place to another at a point without taking into account water that changes form. Inside a given system, the total change in water with time is zero. However, concentrations are allowed to move with the wind.
In geology, a rock composed of different minerals may be a compositional data point in a sample of rocks; a rock of which 10% is the first mineral, 30% is the second, and the remaining 60% is the third would correspond to the triple [0.1, 0.3, 0.6]. A data set would contain one such triple for each rock in a sample of rocks.
A Stiff diagram, or Stiff pattern, is a graphical representation of chemical analyses, first developed by H.A. Stiff in 1951.It is widely used by hydrogeologists and geochemists to display the major ion composition of a water sample.
In fisheries and conservation biology, the catch per unit effort (CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance. A decreasing CPUE indicates overexploitation, while an unchanging CPUE indicates sustainable harvesting. [1]
A jengu (pl. miengu) is a water spirit in the traditional beliefs of the Sawabantu groups of Cameroon, like the Duala, Bakweri, Malimba, Subu, Bakoko, Oroko people. Among the Bakweri, the term used is liengu (plural: maengu). [1] Miengu are similar to bisimbi (singular: simbi) in the Bakongo spirituality and Mami Wata.
