SAF Water Quality & Management 2

Question 1

Which forestry practice is most effective at reducing peak stream flows during storm events?

Accepted Answer

Maintaining forested riparian buffers

Answer

Forested riparian buffers intercept runoff, promote infiltration, and slow water movement, significantly reducing peak flows during storms.

Question 2

What is the primary function of a settling pond in forest road drainage systems?

Accepted Answer

To allow suspended sediment to settle before discharge

Answer

Settling ponds trap sediment from road runoff by slowing water flow and allowing particles to settle before water enters streams.

Question 3

The term 'hyporheic zone' refers to which area in a stream ecosystem?

Accepted Answer

The subsurface area where stream and groundwater mix

Answer

The hyporheic zone is the saturated subsurface region beneath and beside streams where surface water and groundwater exchange occurs.

Question 4

Best Management Practices (BMPs) for forestry are primarily designed to:

Accepted Answer

Prevent water quality degradation during and after forestry operations

Answer

Forestry BMPs are site-specific practices developed to protect water quality by minimizing nonpoint source pollution from logging activities.

Question 5

Which soil texture class has the greatest potential for surface runoff and erosion?

Accepted Answer

Clay loam

Answer

Clay loam soils have low permeability due to fine particles, promoting surface runoff and making them highly susceptible to erosion when disturbed.
