EROSION, SEDIMENTATION AND SOIL
MANAGEMENT EXAM QUESTIONS AND
100% VERIFIED ANSWERS!!
What is erosion?
The process by which the land surface is worn away by the action of wind, water, and gravity.
What is sedimentation?
The settling out of soil particles transported by water and wind.
What are the two types of soil erosion?
Wind erosion and water erosion.
How can water erosion be classified?
Overland erosion and stream and channel erosion.
What are the four processes of overland erosion?
Splash or raindrop erosion, sheet erosion, rill erosion, and gully erosion.
What are the four principal factors influencing soil erosion?
Soil characteristics, vegetative cover, topography, and climate.
List three physical effects of erosion and sedimentation.
Increased flooding, reduced hydraulic capacity in rivers, and increased water treatment costs.
List three biological effects of erosion and sedimentation.
Reduced light for aquatic plants, clogs fish gills, and disrupts food chain.
What should be considered when planning development to fit the terrain?
Topography, soils, drainage patterns, and natural vegetation.
What practices should be applied to protect disturbed areas from runoff?
Perimeter control practices.
, What is the importance of stabilizing disturbed areas immediately after grading?
To prevent raindrop impacts from causing erosion.
What is the rainfall erosion index?
The only factor in the Universal Soil Loss Equation that is beyond the developer's control.
What are the factors most easily manipulated by developers in erosion control?
Slope length & gradient, and cover factor.
What is the RUSLE used for?
To predict soil loss on construction sites.
Who can you contact for soil survey information?
FDOT, FDEP, Water Management District, Mayor's Office, or NRCS.
What are the five soil forming factors?
Climate, topography, organisms, parent material, and time.
What is the requirement for a temporary gravel construction entrance?
Must extend the full width of the entrance, be at least 50 feet long, and at least 6 inches thick.
What is the maximum drainage area for a silt fence under sheet flow conditions?
¼ acre per 100 feet of barrier length.
What is the average usable life of a silt fence?
6 months.
What should be done with truck washing during construction?
It should be done in a designated area, not near the perimeter controls.
Is waste disposal a problem for workers and subcontractors?
True, it is a problem.
Is the public's understanding of dust during construction important?
