All Flashcards
Effect of deforestation on soil erosion?
Increased soil erosion and loss of topsoil.
Effect of deforestation on runoff rate?
Faster runoff and increased flooding potential.
Effect of deforestation on water quality?
Increased sediment and decreased water filtration.
How does urbanization affect watersheds?
Increases runoff, pollution, and habitat destruction.
Define watershed.
Land area that drains into a specific body of water.
What are headwaters?
The starting points of a watershed, often in high elevations.
What are sub-watersheds?
Smaller streams and rivers that branch off within a larger watershed, all flowing to the same discharge point.
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.
Why are watershed characteristics interconnected?
Changes in one area can affect the entire watershed system.
How does length of a watershed impact runoff?
A longer watershed means it takes more time for runoff to reach the outlet.
