Hydrus is a small constellation in the deep southern sky. It was one of twelve constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm (14 in) diameter celestial globe published in late 1597 (or early 1598) in Amsterdam by Plancius and Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. The French explorer and astronomer Nicolas Louis de Lacaille charted the brighter stars and gave their Bayer designations in 1756. Its name means "male water snake", as opposed to Hydra, a much larger constellation that represents a female water snake.

Hydrus (disambiguation) | Introduction
The Hydrus (also known as "Enhydros, Enidros, Hildris, Hydra, Idra, Idres, Ydre, Ydris", and "Ydrus") is a creature from Medieval bestiaries. They were said to be found in the Nile River. While in the Nile, a crocodile would roll the hydrus in the mud before eating the smaller creature. However, once inside the crocodile's stomach, the hydrus would burst free from the stomach lining. In medieval Christian tradition, this bursting free from the crocodile became an emblem of the resurrection of Christ bursting free from Hell. There is considerable confusion in applying the name hydrus and its variations to beasts.
Hydrus (legendary creature) | Introduction
The root of the word itself refers to water, and this led to several beasts, mostly serpents, being so labeled. Isidore of Seville lists the hydros, a water snake that causes those bitten to swell up, the cure for which is the dung of an ox. The hydrus was also confused with the Hydra of the Hercules legend, some texts saying that it was a many-headed water dragon, living in the swamp of Lerna, that could grow new heads.
Hydrus (legendary creature) | Introduction
A hydrus has no set appearance. Normally it is considered to be a water snake, although Pliny the Elder believed that it was an otter. Other animals the hydrus has been thought of as include a bird, a dragon, and a mongoose.

Hydrus (software) | Applications
Hydrus was one of the twelve constellations established by the Dutch astronomer Petrus Plancius from the observations of the southern sky by the Dutch explorers Pieter Dirkszoon Keyser and Frederick de Houtman, who had sailed on the first Dutch trading expedition, known as the "Eerste Schipvaart", to the East Indies. It first appeared on a 35-cm (14 in) diameter celestial globe published in 1598 in Amsterdam by Plancius with Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in the German cartographer Johann Bayer's "Uranometria" of 1603. De Houtman included it in his southern star catalogue the same year under the Dutch name "De Waterslang", "The Water Snake", it representing a type of snake encountered on the expedition rather than a mythical creature.

HYDRUS-1D traces its roots to the early work of van Genuchten and his SUMATRA and WORM models, as well as later work by Vogel (1987) and Kool and van Genuchten (1989) and their SWMI and HYDRUS models, respectively. While Hermitian cubic finite element numerical schemes were used in SUMATRA and linear finite elements in WORM and the older HYDRUS code for solution of both the water flow and solute transport equations, SWMI used finite differences to solve the flow equation. Various features of these four early models were combined first in the DOS-based SWMI_ST model (Šimůnek et al., 1993), and later in the Windows-based HYDRUS-1D simulator (Šimůnek et al., 1998).

The current HYDRUS (2D/3D) suite of software and their predecessors have a long history. The origin of these models can be traced back to the early work of Dr. Shlomo Neuman and collaborators (e.g., Neuman, 1972) who developed their UNSAT model at the Hydraulic Engineering Laboratory of Technion – Israel Institute of Technology, in Haifa, Israel, long before the introduction of personal computers. UNSAT was a finite element model simulating water flow in two-dimensional variably-saturated domains as described with the Richards equation. The model additionally considered root water uptake as well as a range of pertinent boundary conditions required to ensure wide applicability of the model.

The temperature dependence of the soil hydraulic properties was included by considering the effects of temperature on surface tension, dynamic viscosity and the density of water. The heat transport equation in CHAIN_2D considered transport due to conduction and advection with flowing water. The solute transport equations considered advective-dispersive transport in the liquid phase, as well as diffusion in the gaseous phase. The transport equations also included provisions for nonlinear nonequilibrium reactions between the solid and liquid phases, linear equilibrium reactions between the liquid and gaseous phase, zero-order production and two first-order degradation reactions: one which was independent of other solutes, and one which provided the coupling between solutes involved in the sequential first-order decay reactions.

The SWMS_2D and CHAIN_2D models formed the bases of versions 1.0 (for 16-bit Windows 3.1) and 2.0 (for 32-bit Windows 95) of HYDRUS-2D (Šimůnek et al., 1999). A unique feature of HYDRUS-2D was that it used a Microsoft Windows based Graphics User Interface (GUI) to manage the input data required to run the program, as well as for nodal discretization and editing, parameter allocation, problem execution, and visualization of results. It could handle flow regions delineated by irregular boundaries, as well as three-dimensional regions exhibiting radial symmetry about the vertical axis. The code includes the MeshGen2D mesh generator, which was specifically designed for variably-saturated subsurface flow and transport problems.

The hydria (; plural hydriai) is a form of Greek pottery that existed between the Late Geometric Period (7th century BC) and the Hellenistic period (3rd century BC). The etymology of the word hydria was first noted when it was stamped on a hydria itself, its direct translation meaning ‘jug’. It is a type of water-carrying vessel, but it had many other purposes. As time progressed the hydria developed into many forms, some of which were smaller or of a different material. These variants were decorated with detailed figures to represent Greek mythological stories, as well as scenes of daily life, providing extensive insight into Ancient Greek culture and society.

Also included is a small catalog of unsaturated soil hydraulic properties, as well as pedotransfer functions based on neural networks. Both HYDRUS models also consider various provisions for simulating non-equilibrium flow and transport. The flow equation for the latter purpose can consider dual-porosity-type flow with a fraction of the water content being mobile, and a fraction immobile. The transport equations additionally were modified to allow consideration of kinetic attachment/detachment processes of solutes to the solid phase, and hence of solutes having a finite size. This attachment/detachment feature has been used by many recently to simulate the transport of viruses, colloids, and bacteria.

The hydria has three handles, two horizontal ones at its sides and a vertical one on its back. The horizontal handles were pulled from balls of clay which were then attached below the shoulder on the hydria. The handles were cylindrical and upturned. The vertical handle was also pulled from a ball of clay but it was centre-ridged and oval shaped. It was attached at the lip and shoulder of the hydria. The handles were then burnished by hand rather than on the potter's wheel.

Giraffids are represented in the late Miocene of the Siwaliks by large Sivatheriinae such as "Sivatherium", "Bramatherium", "Helladotherium", and "Hydaspitherium". "Hydapitherium" has been proposed to be synonymous with "Bramatherium". "H. megacephalum" is restricted to the Dhok Pathan Formation (, paleocoordinates ) in northern Pakistan. Four separate species of "Hydaspitherium" were described more than a century ago, but concluded that their differences can be explained as sexual dimorphism and intraspecific variability: "H. birmanicum" () is based on a single right upper molar.
