Latest Update
Soil erosion can be classified as either _____ erosion or _____ erosion, and the sources can be
either _____ or ____ wind or water; natural or manmade
Water erosion can be classified as either _____ erosion or _____ and ____ erosion overland
(sheet) ; stream and channel
Four processes of overland erosion are? Splash or rain drop erosion, sheet erosion, rill
erosion, and gully erosion
Four principle factors influencing soil erosion are? Soil characteristics, vegetative cover,
topography, and climate
List three physical effects of erosion and sedimentation: Increased flooding reduced
hydraulic capacity in rivers, streams, channels, reservoirs; increased maintenance of
stormwater systems; increased water treatment costs; and decreased recreational value
List three biological effects 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
Apply ________ practices to protect the disturbed area from off-site runoff and to protect off-
site areas from sediment damage perimeter control
Apply _____ practices to prevent excessive on-site damage erosion control
, Keep runoff velocities ____ and ____ runoff on the site low;retain
