In hydrology, the discharge of a river is the volume of water transported by it in a certain amount of time. The unit used is usually m³/s (cubic meters per second). For example, the average discharge of the Rhine river is 2200 m³/s. Water covers 70% of the Earths surface. ...
A river is a large natural waterway. ...
Water is a tasteless, odorless substance that is essential to all known forms of life and is known as the universal solvent. ...
The definition, agreement and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. ...
Loreley At 1,320 kilometres (820 miles) and an average discharge of more than 2,000 cubic meters per second, the Rhine (Dutch Rijn, French Rhin, German Rhein, Italian: Reno, Romansch: Rein, ) is one of the longest and most important rivers in Europe. ...
The discharge of a river can be estimated by taking the area of a cross-section of the river and multiplying it by the river's average velocity. Area is a physical quantity expressing the size of a part of a surface. ...
The velocity of an object is simply its speed in a particular direction. ...
In absolute terms, the greater the discharge of a river, the more sediment it may carry. In relative terms the ability to carry sediments depends on the settling velocity, the speed of the flow. Look up absolute in Wiktionary, the free dictionary. ...
Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid. ...
Speed is the rate of motion, or equivalently the rate of change of position, many times expressed as distance d moved per unit of time t. ...
CALCULATING DISCHARGE To calculate discharge you need to work out the average velocity, the average depth and the width and times them by each other. The velocity of an object is simply its speed in a particular direction. ...
