The Oder (/ ˈ oʊ d ər / OH-dər, German: ⓘ; Czech, Lower Sorbian and Polish: Odra; [a] Upper Sorbian: Wódra) is a river in Central Europe. It is Poland's second-longest river and third-longest within its borders after the Vistula and its largest tributary the Warta . [ 1 ]
The stream order or waterbody order is a positive whole number used in geomorphology and hydrology to indicate the level of branching in a river system.. There are various approaches [1] to the topological ordering of rivers or sections of rivers based on their distance from the source ("top down" [2]) or from the confluence (the point where two rivers merge) or river mouth ("bottom up" [3 ...
The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...
A diagram of a possible river with the Strahler number of each tributary labeled. In hydrology, a stream order is a positive integer used to describe the level of river branching in a drainage basin. [18] Several systems of stream order exist, one of which is the Strahler number. In this system, the first tributaries of a river are 1st order ...
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The Oder–Neisse line (German: Oder-Neiße-Grenze, Polish: granica na Odrze i Nysie Łużyckiej) is an unofficial term for the modern border between Germany and Poland. The line generally follows the Oder and Lusatian Neisse rivers, meeting the Baltic Sea in the north.

The water in this stream forms varying currents as it makes its way downhill. In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry.
