Discharge regime, [1] flow regime, or hydrological regime (commonly termed river regime, but that term is also used for other measurements) is the long-term pattern of annual changes to a stream's discharge at a particular point. Hence, it shows how the discharge of a stream at that point is expected to change over the year. [2]
The Atchafalaya is 137 miles long and is the fifth largest river in North America, by discharge. In The Netherlands, the IJssel is a distributary of the Rhine. With a length of around 127 kilometers, it is the longest river to start and end within The Netherlands. [13] Unlike the Rhine, which flows into the North Sea, it flows into the IJsselmeer.
The river's discharge at that location depends on the rainfall on the catchment or drainage area and the inflow or outflow of groundwater to or from the area, stream modifications such as dams and irrigation diversions, as well as evaporation and evapotranspiration from the area's land and plant surfaces. In storm hydrology, an important ...
The discharge calculation can be summarised as Q = CLH n. where Q is the volumetric flow rate of fluid (the discharge), C is the flow coefficient for the structure (on average a figure of 3.33), L is the width of the crest, H is the height of head of water over the crest, n varies with structure (e.g., 3 ⁄ 2 for horizontal weir, 5 ⁄ 2 for v ...
It is described by the fact that the discharge through a river of an approximate rectangular cross-section must, through conservation of mass, equal Q = u ¯ b h {\displaystyle Q={\bar {u}}bh} where Q {\displaystyle Q} is the volumetric discharge, u ¯ {\displaystyle {\bar {u}}} is the mean flow velocity, b {\displaystyle b} is the channel ...
Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. [2] Diagram of a river's left and right banks
Reasons for the quality being less than good include physical modification of the channel and some sewage discharge. Section
A drainage system is described as accordant if its pattern correlates to the structure and relief of the landscape over which it flows. [2]A discordant system or pattern does not correlate to the topography and geology of the area.
