?
what is the discharge of the river?
the volume of water flowing through the river measured in cubic meters per second.
1 of 12
what is the velocity of a river?
the speed the water flows (the velocity will change throughout the course of the river)
2 of 12
what is the river depth?
how deep the river is, this will change throughout the course of the river due to material on the river bed. therefore it's best to calculate the mean depth.
3 of 12
what is the river width?
the distance between the points where water comes into contact with each river bank.
4 of 12
what is the wetter perimeter of a river?
the wetted perimeter or occupied channel width is the entire length of the bed and river (sides) in contact with water
5 of 12
how do you measure the wetter perimeter?
wetter perimeter = width + depth + depth
6 of 12
what is the cross profile?
river cross profiles show you a cross-section of a river's channel and valley at certain points in the river's course
7 of 12
what is sediment size and type?
the aim of this is to measure the size and shape of a sample of stones from each site visited in the river
8 of 12
a) how is an igneous rock made?
b) where do you find it?
c) is it a hard or soft rock?
a) is formed when hot, molten rock crystallizes and solidifies
b) by volcanoes
c) usually very hard

what does the Bradshaw model look like?
.
10 of 12
a) how is a sedimentary rock made?
b) where do you find it?
c) is it a hard or soft rock?
a) formed from pre-existing rocks or pieces of once-living organisms
b) often start as sediments carried in rivers and deposited in lakes and oceans
c) mostly soft
11 of 12
a) how is a metamorphic rock made?
b) where do you find it?
c) is it a hard or soft rock?
a) started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form.
b)deep within the Earth or where tectonic plates meet
c)mostly hard
