Exam 3 Practice

Front

What is the expected dewatering time for a sedimentation basin with a volume of 2,000 ft³ and a perforated riser with 0.2-inch diameter perforations spaced 0.5 feet apart?

Back

5 days

Front

Define AMCrz in the context of soil series.

Back

AMCrz is a measure of the available moisture capacity for a specific soil series, indicating its ability to retain water for plant use.

Front

True or False: There can be no runoff from a developed site for rain events smaller than a 100-year return period.

Back

False

Front

What irrigation soil group does the Wooster series belong to?

Back

Group 2

Front

Given an irrigation system with a 20 x 30 spacing, what is the wetted diameter?

Back

40 feet

Front

What is the purpose of a sedimentation basin in water management?

Back

To remove suspended solids from water through gravitational settling.

Front

Explain the significance of rooting depth in soil series classification.

Back

Rooting depth affects the soil's ability to support plant growth by determining how much moisture and nutrients can be accessed.

Front

What factors influence the dewatering time of a sedimentation basin?

Back

Factors include basin volume, perforation size, spacing, and inflow rate.

Front

Define runoff in the context of site development.

Back

Runoff is the flow of water that occurs when excess rainwater, meltwater, or other sources flows over the ground.

Front

What is the role of perforated risers in sedimentation basins?

Back

Perforated risers facilitate the controlled release of water while allowing sediment to settle.
