tributary
|
A stream or river that flows into a main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean.
|
|
|
confluence
|
A confluence is the meeting of two or more bodies of water. Also known as a conflux, it refers either to the point where a tributary joins a larger river, called the main stem, or where two streams meet to become the source of a river of a new name.
|
|
|
river
|
A river is a natural watercourse, usually freshwater, flowing towards an ocean, a lake, a sea, or another river.
|
|
|
catchment
|
The area drained by a river or body of water. Also called catchment basin.
|
|
|
riparian fringe
|
The riparian zone---also called riparian area, strip, fringe or buffer---is the area directly along the edge of a river or stream.
|
|
|
channel
|
A type of landform consisting of the outline of a path of relatively shallow and narrow body of fluid, most commonly the confine of a river, river delta or strait.
|
|
|
Delta
|
a landform that is formed at the mouth of a river, where the river flows into an ocean, sea, estuary, lake, or reservoir. Deltas are formed from the deposition of the sediment carried by the river as the flow leaves the mouth of the river.
|
|
|
Estuary
|
An estuary is a partly enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea.[1]
|
|
|
Levee
|
embankment, floodbank or stopbank is an elongated naturally occurring ridge or artificially constructed fill or wall, which regulates water levels. It is usually earthen and often parallel to the course of a river in its floodplain or along low-lying coastlines.[1]
|
|
|
sediment
|
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice.
|
|
|
Alluvial soil
|
a fine-grained fertile soil deposited by water flowing over flood plains or in river beds.
|
|
|
Alluvial plains
|
An alluvial plain is a largely flat landform created by the deposition of sediment over a long period of time by one or more rivers coming from highland regions, from which alluvial soil forms
|
|
|
river basins
|
A river basin is an area of land drained by a river and its tributaries.
|
|
|
water shed
|
is the area of land where all of the water that is under it or drains off of it goes into the same place.
|
|
|
meander
|
To follow a winding and turning course: Streams tend to meander through level land.
|
|
|
bed load
|
the sand, gravel, boulders, or other debris transported by rolling or sliding along the bottom of a stream.
|
|
|
erosion
|
is the process by which soil and rock are removed from the Earth's surface by wind or water flow,
|
|
|
distributaries
|
a stream that branches off and flows away from a main stream channel.
|
|
|
oxbow lake
|
a U-shaped body of water formed when a wide meander from the main stem of a river is cut off to create a lake.
|
|
|
silt
|
Silt is a solid, dust-like sediment that water, ice, and wind transport and deposit. Silt is made up of rock and mineral particles
|
|
|
pH
|
The pH of river water is the measure of how acidic or basic the water is on a scale of 0-14.
|
|
|
dissolved oxygen
|
(DO) is the amount of oxygen that is present in the water. It is measured in milligrams per liter (mg/L),
|
|
|
turbidity
|
Turbidity is a measure of water clarity how much the material suspended in water decreases the passage of light through the water.
|
|
|
water temperature
|
a measure of the warmth or coldness of water.
|
|
|
displacement
|
A displacement is the shortest distance from the initial to the final position of a point. it is the length of an imaginary straight line between the start and the finish.
