Velocity increases as more water is added to rivers via tributary rivers. This means that less of the water is in contact with the bed of the river and the mouth so there is less energy used to overcome friction.]]> 2021-01-13 04:44:36 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081530002 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081530528 Upper Course:
- A stream with fast velocity, eroding the ground vertically and forming V-shaped valleys, it can also form waterfalls and gorges.

Middle Course:
- The gradient of the river flattens and the river winds through the earth, forming meanders. When these meanders get eroded through, an oxbow lake can form. The velocity of the river is the fastest on the outer bends of the meander and slowest on the insides of the meander. There is also more lateral erosion instead of vertical erosion.

Lower Course:
- Near the mouth of the river, deltas can form with distributaries and braiding rivers.]]> 2021-01-13 04:44:57 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081530528 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081530675 - fast moving streams will continue to erode bank and eventually create an oxbow lake
- meanders with high velocity cut into landscape forming a cliff. Low velocity areas deposit rocks
- dischare incre

2nd task
i think discharge increases as the river goes down because more smaller rivers join the main channel.]]> 2021-01-13 04:45:03 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081530675 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081531225 Upper course - fast moving streams, v-shaped valleys, waterfalls forges, more vertical erosion

Middle course - meanders, decrease in gradient, decrease in vertical erosion, more lateral erosion.

Lower course - flat land, decrease in gradient, floodplains, as river reaches body of water, more deposition occurs.

Discharge increases from upper course to lower course

Velocity increases from upper course to lower course, but upper course more turbulent]]> 2021-01-13 04:45:26 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081531225 anbr22 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081532469 Upper course - this is where the river is very fast flowing which is assisted by gravity as it is steep. Heavy rainfall fall onto the landscape and collects into a stream starting the source. Vertical erosion is present also forming waterfalls by the water cutting back at the water fall, eroding it.

Middle Course - flattens out and flows through agricultural land
Meanders are present and ox bow lakes form.

Lower course -  ]]> 2021-01-13 04:46:13 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081532469 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081534748 Upper Course
- V-shape valley
- slow flowing (high velocity)
- waterfalls - form gorges
- thin width
- more discharge

Middle Course
- river is flatter
- meanders
- outside of the bend eroded
- inside of the bend - materials are deposited
- ox-bow lakes
- flate lands -threat of floods

Lower Course
- more discharge

- V shape valley
- fast velocity
- More erosion of bed (vertical erosion)
- Rapids
- waterfalls

High velocity meanders cause erosion, oxbow lakes
 
Interlocking Spurs

Lower course
- Gradient flattens
- Discharge and velocity increase due to tributaries meeting the main channel at the points of confluence, increasing the amount of water in the main channel. 
- in the lower course, PE is converted to KE, therefore increasing the velocity]]> 2021-01-13 04:48:15 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081535581 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081537044 upper course: 
- streams increase in size by the power of rivulets that are feeding into it.
- v shaped valleys are formes
fast flowing water means high capacity ]]> 2021-01-13 04:49:13 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081537044 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081548844 Discharge: the number of tributaries which have joined the river is higher at the lower course, thus, the volumes add up, so the volume of water at a given point will be higher

Velocity: GPE converted to KE]]> 2021-01-13 04:56:18 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081548844 anbr22 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081548930 I think the discharge increases as we go down the river as it has had more tributaries connecting to the large channel increases, increasing the amount of water entry. 

Low velocity in upper course because there are lots of rocks causing friction - thus making it difficult for the water to move quickly. In the lower course of the river there is less friction, increasing velocity.]]> 2021-01-13 04:56:21 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081548930 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081549027 The upper course is has less velocity as it has a steep gradient which means lots of potential energy. In the middle course the potential energy is converted into kinetic energy which causes an increase in velocity. The lower course has very little potential energy and lots of kinetic energy which means it has the highest velocity. 

Discharge, increases as we move into the lower course of the river as there is more water entering into the river through tributaries by the time we reach the mouth of the river, and there is higher velocity.]]> 2021-01-13 04:56:25 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081549027 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081549359 Discharge increases along the course of the river because more and more tributaries join into the main channel, increasing the amount of discharge in a river.

As discharge increases, the velocity also increases because there is an increase in energy. With a shallower gradient, there is less gravitational potential energy so there is more kinetic energy and a faster velocity.]]> 2021-01-13 04:56:40 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081549359 https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081551317 i think it will increase as the smaller rivers connecting to the river will put more water into the main river ]]> 2021-01-13 04:58:02 UTC https://padlet.com/list4/21avrqd6ei6yqtnv/wish/1081551317
