Water On The Land

Front 1

Deposition

Back 1

Sand and silt being dropped on a bank by the river, mostly in high flow

Front 2

Meander

Back 2

A loop in the river where erosion occurs on the outside bend where there is a fast flow and deposition on the inside bend where there is a slow flow. A river cliff is formed on the outside bend and a river beach onthe inside bend.

Front 3

Ox-Bow lake

Back 3

Formed when a meander cuts through the land and the river then straightens out.

Front 4

Traction

Back 4

Large boulders rolling along the river bed

Front 5

Saltation

Back 5

Small stones and pebbles bouncing along the river bed

Front 6

Suspention

Back 6

Mud and silt suspended in the river

Front 7

Solution

Back 7

Minerals dissolved in the river water

Front 8

Hydraulic Action

Back 8

The sheer force of the water against the river banks

Front 9

Attrition

Back 9

Stones banging against each other, making them smaller, rounder and more smooth

Front 10

Corrosion

Back 10

Acid in the water disolves stones containing calcium e.g. limestone

Front 11

Corrasion

Back 11

Rocks and pebbles wearing away the beds and banks - sand paper effect

Front 12

Hard Engineering

Back 12

Making something to protect areas around the river. Less environmentally friendly (Human) e.g. dams

Front 13

Soft Engineering

Back 13

using more environmentally friendly methods to protect areas around the river (physical/natural) e.g. flood plain zoning
