It formed the backbone of a waterway stretching some 382 miles ( 614 km ), linking a number of lakes and rivers to provide a route from Gothenburg ( Swedish: Göteborg ) on the west coast to Söderköping on the Baltic Sea via the river Göta älv and the Trollhätte kanal, through the large lakes Vänern and Vättern.

An upper limit of 750 BC is indicated by a number of considerations, such as the probability that his work was written down, the fact that he mentions a sanctuary at Delphi that was of little national significance before c. 750 BC ( Theogony l. 499 ), and he lists rivers that flow into the Euxine, a region explored and developed by Greek colonists beginning in the 8th century BC.

Both the Tigris and the Euphrates break into a number of channels in the marshland area, and the flow of the rivers is substantially reduced by the time they come together at Al Qurnah.

Luxembourg has a number of minor rivers, such as the Eisch, the Alzette, and the Pétrusse, but the main river is the Moselle with its tributaries-the Sûre and the Our.

* Mayo River ( disambiguation ), a number of rivers called " Mayo "

The Ohio River as a whole is ranked as the most polluted river in the US based on 2009 and 2010 data although the more industrial and regional Ohio tributary, Monongahela River, which the data names as home to the biggest polluter in the state, ranked behind 16 other American rivers for pollution at number 17, while the Allegheny is not cited as a polluted river.

The few remaining salt marshes now represent most of California's remaining salt marsh, supporting a number of endangered species and providing key ecosystem services such as filtering pollutants and sediments from the rivers.

Aulus Plautius lands with four legions ( 20, 000 men ) and the same number of auxiliaries at Rutupiae ( modern Richborough, on the east coast of Kent ) and defeats the Britons, led by Caratacus and Togodumnus, in battles on the rivers Medway and Thames.

Departments were created in 1790 as a rational replacement of Ancien Régime provinces in view of strengthening national unity ; almost all of them are therefore named after rivers, mountains or coasts rather than after historical or cultural territories, unlike regions, and some of them are commonly referred to by their two-digit postal code number, which was until recently used for all vehicle registration plates.

Marked trails lead to a number of peaks, sites and fishing lakes and rivers.

A large number of rivers, all direct or indirect tributaries of the Po, cross the plains of Lombardy.

This carbonate aquifer has historically been providing high quality water for nearly 2 million people, and even today, is full because of tremendous recharge from a number of area streams, rivers and lakes.

A number of large rivers – the Ganges and its distributaries such as Padma and Hooghly, Brahmaputra and its distributaries such as Jamuna, Meghna, Irrawaddy River, Godavari, Mahanadi, Krishna and Kaveri – flow into the Bay of Bengal.

The principal area of settlement in the 5th century has been identified as between the lower Ouse and Cuckmere rivers in East Sussex, based on the number of Anglo-Saxon cemeteries there.

Underwater Archaeology now has a number of branches including, after it became broadly accepted in the late 1980s maritime archaeology: the scientifically based study of past human life, behaviours and cultures and their activities in, on, around and ( lately ) under the sea, estuaries and rivers.

A number of rivers in the western part of the country, however, flow eastward into the Essequibo River, draining the Kaieteur Plateau.

Water resources are relatively plentiful and the country is traversed by a number of perennial rivers and enjoys considerable mineral reserves.

A number of low rivers cross the city, including the Vladaiska and the Perlovska.

The area is drained by a large number of rivers and has formed a characteristic vegetation known as muskeg.

A number of rivers cross the plateau — notably the Blue Nile rising from Lake Tana.

Several other permanent rivers and streams also drain into the Persian Gulf, while a number of small rivers that originate in the northwestern Zagros or Alborz drain into the Caspian Sea.

The Drechtsteden ( Dutch for " Drecht cities ") are a number of towns and cities bordering each other in the delta area of the rivers Oude Maas, Noord, and Beneden-Merwede in the province of South Holland, the Netherlands.

To provide the continuous flow of information basic to administrative decisions, a number of institutions have established offices of institutional research.

In this way, amperes can be viewed as a flow rate, i. e. number of particles ( charged ) transiting per unit time, and coulombs simply as the number of particles.

The proposed change would define 1 A as being the current in the direction of flow of a particular number of elementary charges per second.

The ratio of the flow speed to the speed of sound was named the Mach number after Ernst Mach, who was one of the first to investigate the properties of supersonic flow which included Schlieren photography techniques to visualize the changes in density.

The Mach number is used to evaluate whether the incompressibility can be assumed or the flow must be solved as compressible.

In air, compressibility effects are usually ignored when the Mach number in the flow does not exceed 0. 3 ( about 335 feet ( 102m ) per second or 228 miles ( 366 km ) per hour at 60 ° F ).

In general, this is the case where the Mach number in part or all of the flow exceeds 0. 3.

* There are a small, fixed number of keywords, including a full set of flow of control primitives:,,,, and.

Reflux is a flow from the condenser back to the column, which generates a recycle that allows a better separation with a given number of trays.

Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each springtime in a lake.

For flow of gases, to determine whether to use compressible or incompressible fluid dynamics, the Mach number of the flow is to be evaluated.

Hall effect sensors are readily available from a number of different manufacturers, and may be used in various sensors such as rotating speed sensors ( bicycle wheels, gear-teeth, automotive speedometers, electronic ignition systems ), fluid flow sensors, current sensors, and pressure sensors.

Vorticity is measured by a number called the circulation, so an airfoil in a steady flow will develop sufficient circulation to satisfy the Kutta condition.

The Kutta condition allows for the correct choice among an infinite number of flow solutions that otherwise obey the laws of conservation of mass and conservation of momentum.

The lift force frequency is characterised by the dimensionless Strouhal number, which depends ( among others ) on the Reynolds number of the flow.

Shown is a sphere in Stokes flow, at very low Reynolds number.

The dimensionless Reynolds number is an important parameter in the equations that describe whether flow conditions lead to laminar or turbulent flow.

In the case of flow through a straight pipe with a circular cross-section, at a Reynolds number below the critical value of approximately 2040 fluid motion will ultimately be laminar, whereas at larger Reynolds number the flow can be turbulent.
