Watersheds Flashcards
What happens when you reduce the discharge of a river
Sedimentation increases and turbidity decreases
Do changes upstream affect locations downstream
Yes, whatever happens upstream gets carried downstream
How do you know when water discharge has increased in a river?
- velocity increased
- volume of water increases
- sedimentation decreases
- turbidity increases
How does velocity affect a river’s discharge?
Increases in velocity increases discharge
What are some characteristics of water systems that have high turbidity?
Low sedimentation
high oxygen levels
low clarity
high velocity
The relationship between turbidity and sedimentation?
As one decreases the other increases
What is the relationship between water temperature and the amount of dissolved oxygen?
The colder the water, the higher the dissolved oxygen
What is the relationship between turbidity and the amount of light transmitted
The higher the turbidity the less light can transmit
Estuary
The part of the ocean where fresh and salt water meet
What is the relationship between velocity and the amount of dissolved oxygen
As one increases, the other does as well
What is the relationship between dissolved oxygen and the amount of fish in the water
The more the dissolved oxygen, the larger the fish a water system can support
