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 & 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 are headwaters?
Starting points of a watershed, often in high elevations.
What are sub-watersheds?
Smaller streams and rivers branching from the main watershed.
