All Flashcards
How does watershed size affect water volume?
Larger watershed = more runoff & greater water discharge.
How does slope affect runoff?
Steeper slope = faster runoff, increased erosion.
How does soil type impact water absorption?
Sandy soils: more infiltration. Clay soils: retain more water.
What is the role of vegetation in a watershed?
Prevents soil erosion, improves soil fertility, and helps filter water.
What happens when deforestation occurs in a watershed?
Increased erosion, faster runoff, decreased water quality.
How does watershed length affect runoff?
A longer watershed means it takes more time for runoff to reach the outlet.
What is a watershed?
Land area that drains into a specific body of water.
What are headwaters?
Starting points of a watershed, often in high elevations.
What are sub-watersheds?
Smaller streams and rivers branching off within a larger watershed.
How does watershed size affect water volume?
Larger watershed = more runoff and greater water discharge.
How does slope affect runoff?
Steeper slopes mean faster runoff and increased erosion.
How does soil type affect water absorption?
Sandy soils allow more infiltration; clay soils retain more water.
What is the role of vegetation in a watershed?
Prevent soil erosion, improve soil fertility, filter water.
How do watershed characteristics affect water quality?
Characteristics influence water flow, erosion, and filtration, impacting water quality.
What is the impact of deforestation on watersheds?
Deforestation leads to increased erosion, faster runoff, and decreased water quality.
How does urbanization impact watersheds?
Urbanization increases runoff, pollution, and reduces infiltration.
Why is watershed management important?
To manage resources and prevent pollution, ensuring water quality and ecosystem health.
