TRANSPORT

THE MOVMENT OF EROSION MATRAIL BY THE RIVER.

Floatation

MATERIAL MAY FLOAT IN A RIVER.

​SALTATION

when material is bounced along the river bed.

Dragged


{TRACTION}

MATERAIL MAY BE DRAGGED ACROSS THE RIVER BED.

SUSPENSION

WHEN MATERIAL IS HELD UP BY WATER.

DEPOSITION

WHEN THE RIVER DROPS MATERIAL IT HAS CARRIED

DISSOLVED

WHEN MATERIAL ARE NO LONGER VISABLE IN THE WATER

EROSION

IS A MATERIAL WEARING AWAY ROCKS

River



a natural stream of water of fairly large size flowing in a definitecourse or channel or series of diverging and converging channels.


2.a similar stream of something other than water:


a river of lava; a river of ice.

Drainage basin


Is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point at a lower elevation, usually the exit of the basin, where the waters join another waterbody, such as a river, lake, reservoir, estuary, wetland, sea, or ocean.

Resistant Rock

A hard rock which resists being worn down and stands out as hills

Non-Resistant Rock

IS A HARD ROCK THAT HAS COME LOOSE

Hydraulic Action

Is erosion that occurs when the motion of water against a rock surface produces mechanical weathering. Most generally, it is the ability of moving water (flowing or waves) to dislodge and transport rock particles.

Abrasion

The process of scraping or wearing something away.

Plunge Pool

A deep basin excavated at the foot of a waterfall by the action of the falling water.

Undercut

1. To cut away the under part of (something)

Collapse

when something brakes and the falls.

Ledge Waterfall

Water descends vertically over a vertical cliff, maintaining partial contact with the bedrock.

Block/Sheet

Water descends from a relatively wide stream or river.

Classical

Ledge waterfalls where fall height is nearly equal to stream width, forming a vertical square shape.

Curtain

Ledge waterfalls which descend over a height larger than the width of falling water stream.

Plunge

Fast moving water descends vertically, losing complete contact with the bedrock surface. The contact is typically lost due to horizontal thrust of the water before it falls. It always starts from a narrow stream.

Punchbowl

Water descends in a constricted form and then spreads out in a wider pool
