Erosion
is the process by which the land surface is worn away by the action of wind, water, and gravity.
Sedimentation
is the settling out of soil particles transported by water and wind.
Soil erosion can be classified as 2 types. What are they?
Wind and Water.
What are the two sources of Soil erosion.
Natural and Manmade
Water erosion can be classified as two type of erosions. What are they?
Overland and Stream/Channel erosion.
,Four process of overland erosion are?
Splash, sheet, rill, and gully erosion.
Four principle factors influencing soil erosion are?
Soil characteristics, vegetative cover, topography, and climate.
List three physical effect of erosion and sedimentation:
Increased flooding reduced hydraulic capacity in rivers, and streams; increased maintenance of
stormwater systems.; increased water treatments cost; and decreased recreational value.
List three biological effect of erosion and sedimentation:
Reduced light for aquatic plants; clogs fish gills; impairs spawning; disrupts food chain; blankets bottom,
suppresses aquatic life; and disrupts ecosystem.
Planning the development to fit the terrain using the particular:
Topography; soils; drainage patterns; natural vegetation of the site; and minimize the extent of the area
exposed at one time and the duration of exposure.
Perimeter Control Practices
What you apply to protect the disturbed area from off-site runoff and to protect off-site areas from
sediment damage.
, Erosion Control Practices
What you apply to prevent excessive on-site damage.
Keep runoff velocities _____ and _______ runoff on the site
Low and retain
When do you stabilize disturbed areas after final grading to prevent raindrop impacts from causing
erosion.
Immediately
Implement a thorough _____ and _____(inspection) program as required in the Construction Generic
Permit (CGP).
maintenance and follow up
Soil particles smaller than 0.002 mm are classified as ____ and along with ____ are the two soil types
that cause the most erosion/turbidity problems in Florida and the World.
clay and muck
Soils in the Type A hydrologic group have ____ infiltration rates and ____ runoff potential even when
thoroughly wetted.
high and low
