Key Terms: Rivers
Abrasion –The pebbles being transported wear away the bed and banks of the river channel.
Attrition – The particles are knocked about as they are transported, and they gradually become more rounded and reduced in size.
Condensation – When water turns from a gas to a liquid
Confluence – The point at which rivers meet.
Dam – Large concrete structure built to hold back flood water (Hard engineering)
Deposition – The river drops small pebbles and sand on the river bed
Discharge – The amount of water passing a specific point at a given time (Cross Section x Velocity)
Economic sustainability – Ensuring that future generations and businesses will have enough money to keep running
Environmental sustainability – The preservation of resources to maintain biodiversity
Erosion – The wearing away of the bed and banks of the river channel by abrasion, hydraulic action, solution and attrition.
Estuary – The tidal mouth of a river, with large, flat expanses of mud exposed at low tide.
Evaporation – When water turns from a liquid to a gas
Falling limb – When the discharge of a river is decreasing after its peak flow on a hydrograph
Groundwater stores – Water that’s stored in the ground
Hard engineering – Controlled disruption of natural processes using man-made structures
Hydraulic…
