QUESTIONS AND 100% VERIFIED
ANSWERS!!
Chapter 1 - Erosion and Sedimentation
___________ is the process by which the land surface is worn away by the action of wind,
water, and gravity.
erosion
___________ is the settling out of soil particles transported by water and wind.
sedimentation
soil erosion can be classified as either _________ erosion or ________ erosion, and the
sources can be either __________ or ____________
wind; water; natural; manmade
water erosion can be classified as either ______ erosion or _____________ and
____________ erosion.
overland; stream; 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
*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
it is very important to stabilize disturbed areas ________________ after final grading to
prevent raindrop impacts from causing erosion
immediately
implement a thorough ______________ and _____________ program as required in the
Construction Generic Permit (CGP).
maintenance; follow up
