All Flashcards
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.
Effect of deforestation on soil erosion?
Increased soil erosion and loss of topsoil.
Effect of deforestation on runoff rate?
Faster runoff and increased flooding.
Effect of deforestation on water quality?
Increased sediment and decreased filtration.
Effect of steep slopes on erosion?
Steeper slopes lead to more severe erosion.
Effect of clay soils on runoff?
Clay soils lead to more runoff.
Effect of sandy soils on runoff?
Sandy soils lead to less runoff due to higher infiltration.
Effect of increased vegetation on soil erosion?
Reduced soil erosion due to root systems holding soil together.
Effect of pollution on water quality?
Decreased water quality, harming aquatic life and human health.
Effect of urbanization on runoff?
Increased runoff due to impermeable surfaces.
Effect of urbanization on water infiltration?
Reduced water infiltration due to more concrete and less vegetation.
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.
