The Hjulström curve, named after Filip Hjulström (1902–1982), is a graph used by hydrologists and geologists to determine whether a river will erode, transport, or deposit sediment. It was originally published in his doctoral thesis "Studies of the morphological activity of rivers as illustrated by the river Fyris. [1]" in 1935. The graph ...

Nassi-Shneiderman diagrams and Drakon-charts are an alternative notation for process flow. Common alternative names include: flow chart, process flowchart, functional flowchart, process map, process chart, functional process chart, business process model, process model, process flow diagram, work flow diagram, business flow diagram. The terms ...
A classified sample was the one measured by the Chinese researchers from the University of Chinese Academy of Sciences. As an essential symbol of the river formation environment, the river source needs an objective and straightforward and effective method of judging [clarification needed]. A calculation model of river source catchment area ...
Stream gradient may change along the stream course. An average gradient can be defined, known as the relief ratio, which gives the average drop in elevation per unit length of river. [4] The calculation is the difference in elevation between the river's source and the river terminus (confluence or mouth) divided by the total length of the river ...
Diagram showing the Strahler stream order In mathematics , the Strahler number or Horton–Strahler number of a mathematical tree is a numerical measure of its branching complexity. These numbers were first developed in hydrology , as a way of measuring the complexity of rivers and streams, by Robert E. Horton ( 1945 ) and Arthur Newell ...

In practice, the River Continuum Concept is used today mainly for environmental assessment of rivers. River studies that assess riverine biological communities and have determined the species composition of an area can then be compared with the ideal species composition from the River Continuum Concept. From there, any variations in species ...
