Water Cycle
Process of the water cycle in which water vapor in the atmosphere cools and changes back into liquid form.
Condensation
The name for the type of sediment transport where large particles are shoved along the channel bed, like a digger pushing dirt.
traction
Which 2 variables do I need to calculate the area of a stream cross section?
AVERAGE depth and width
What is the name for the flat area on either side of a stream channel called?
Flood plain
Name our case study stream (spelling must be correct)
Okiritoto Stream
Which river has the greatest discharge @ 209,000 cubic meters per second.
Remember Okiritoto Stream was only up to about 0.3cm3/s
The Amazon
Process of the water cycle in which the sun warms water on Earth’s surface. It causes liquid water to change into a gas.
Evaporation
Stream load
If I had to measure the depth of a stream, but I didn't have a 1m ruler, what would I do?

What is a meander?
A bend or curve in a stream
Name the forest that our stream flowed through
Woodhill forest
There are around 170,000 rivers in the world.
What characteristic do (only) 276 of them share?
They flow across more than one country,
What is the driving force of the water cycle?
The sun
The method of transport where sediment bounces along the stream bed.
Saltation
Calculate the discharge of a stream with a width of 8m, an average depth of 2m and an average velocity of 0.5 m/s
Please include units! No units, no points!
8 m3/s
Name the lake that is formed when a meander is cut off. it looks a bit like a long jelly bean - and this word will never be relevant to your life, but everyone seems to want to teach it to students....

Which African river is the World's deepest?
Congo River in Central Africa. Whilst its true depth remains a mystery, scientists believe the waters run at least 230m deep in parts.
Process of the water cycle in which water seeps into groundwater stores (aka aquifers)
Infiltration
The method of transport for all particles small enough to be held up by the turbulence of a stream’s moving water
Suspension
How many students did it take to have a fanstastic field trip to Okiritoto Stream?
45
Name one sediment deposition feature that may occur at the end of a stream/river?
Alluvial fans, deltas, bar
To the nearest kilometre, how long is Okiritoto Stream?
9km
Which river flows through or touches the most countries in Europe?
The Danube - passing through or bordering 10 European nations: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Romania, Moldova, and Ukraine.
Process of the water cycle in which the sun warms plants, it causes water to evaporate out of the leaves through the small openings
Transpiration
Sediment that is too large or heavy to be held up by turbulent water is transported by streamsalong the bottom of the channel.
Bed load
What calculation do I conduct to convert a number from cubic centemeters to cubic metres?
Divide by 1 million
