Ees 101 Ii--3Rd Set

Front 1

Fluvial deposits

Back 1

A sedimentary deposit of material transported by or suspended in a river.

Front 2

alluvium

Back 2

Sediment originating from stream, deposited along floodplain

Front 3

bars

Back 3

A shoal that develops at the mouth of a river as sediment carried by the river is deposited as the current slows or is impedded by wave action.

Front 4

deltas

Back 4

sedimentary deposit that is formed when a stream flows into standing water (base level) and deposits its load of sediment.

Front 5

headwaters

Back 5

Headwaters are the source of a river or stream, the literal waters which feed the river.

Front 6

mouth(of stream)

Back 6

The point at which the stream discharges, possibly via an estuary or delta, into a static body of water such as a lake or ocean

Front 7

base level

Back 7

the elevation in whih a stream can no longer erode the land

Front 8

stream gradient

Back 8

determined by base level

Front 9

v-shaped valley

Back 9

caused by rapid stream flow

Front 10

rapids

Back 10

A rapid is a section of a river where the river bed has a relatively steep gradient causing an increase in water velocity and turbulence.

Front 11

waterfalls

Back 11

where flowing water rapidly drops in elevation as it flows over a steep region or a cliff.

Front 12

alluvial fans

Back 12

deposition of stream sediment in an arid environment. high gradient stream leaves a narrow canyon or gulley and enters a flat plain.

Front 13

braided stream

Back 13

characterized by bars, islands, and a lot of channels. Braided streams develop because the stream contains more sediment than it can transport

Front 14

meandering streams

Back 14

develop on low-gradeint slopes composed of easily eroded sediment

Front 15

oxbow lake

Back 15

a highly sinuous meander will eventually cut across the neck between two meanders and for a more efficient lake forming an oxbow lake.

Front 16

meanders

Back 16

moving water in a stream erodes the outer banks and widens its valley

Front 17

flood plain

Back 17

flat area adjacent to a river channel. where excess water flows outside of the channel on the adjoining and.

Front 18

natural levees

Back 18

coarse sediment deposited along riverbank--increase height of bank.

Front 19

waterfalls

Back 19

where flowing water rapidly drops in elevation as it flows over a steep region or a cliff.

Front 20

alluvial fans

Back 20

deposition of stream sediment in an arid environment. high gradient stream leaves a narrow canyon or gulley and enters a flat plain.

Front 21

braided stream

Back 21

characterized by bars, islands, and a lot of channels. Braided streams develop because the stream contains more sediment than it can transport

Front 22

meandering streams

Back 22

develop on low-gradeint slopes composed of easily eroded sediment

Front 23

oxbow lake

Back 23

a highly sinuous meander will eventually cut across the neck between two meanders and for a more efficient lake forming an oxbow lake.

Front 24

meanders

Back 24

moving water in a stream erodes the outer banks and widens its valley

Front 25

flood plain

Back 25

flat area adjacent to a river channel. where excess water flows outside of the channel on the adjoining and.

Front 26

natural levees

Back 26

coarse sediment deposited along riverbank--increase height of bank.

Front 27

Distributaries

Back 27

is a stream that branches off and flows away from a main stream channel.
