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 ...
3D view. HEC-RAS is simulation software used in computational fluid dynamics – specifically, to model the hydraulics of water flow through natural rivers and other channels.. The program was developed by the United States Army Corps of Engineers in order to manage the rivers, harbors, and other public works under their jurisdiction; it has found wide acceptance by many others since its ...
Stream power, originally derived by R. A. Bagnold in the 1960s, is the amount of energy the water in a river or stream is exerting on the sides and bottom of the river. [1] Stream power is the result of multiplying the density of the water, the acceleration of the water due to gravity, the volume of water flowing through the river, and the ...
To widen the metaphorical river banks, OTs may work with clients to implement universal design methods into their daily lives and/or find other ways to alter the physical environment to make it less of a barrier. Lastly, OTs can work with clients to better utilize existing skill sets and attributes and/or develop new ones to help address barriers.
A WRS, such as a river, an aquifer or a lake, must obey water balance. For example, the volume of water that goes into an aquifer must be equal to the amount that leaves it plus its change in storage. Under various drivers, such as, climate change, population increase, and bad management, water storage of many WRS is decreasing, say per decade ...

In the first step the relationship between stage and discharge is established by measuring the stage and corresponding discharge in the river. And in the second part, stage of river is measured and discharge is calculated by using the relationship established in the first part. Stage is measured by reading a gauge installed in the river.
