Erosion and
sediment control
quiz 1 (45
questions and
answers)
Erosion - answer Process by which the land's
surface is worn away by the action of wind, water,
ice, or gravity.
Splash Erosion - answer Dislodging of soil particles
by raindrop impacts, resulting in dispersal and
mobilization of soil particles.
Sheet-flow Erosion - answer Uniform removal of
saturated soil particles.
, Rill Erosion - answer Long, narrow depression or
soil inclusion caused by increase in slopes and
runoff velocities
Gully erosion - answer Deep and wide depression
caused by concentrated flows.
Streambank Erosion - answer Removal of soil by a
natural drainage pattern.
Shoreline Erosion - answer Removal of soil by high-
energy wave action.
Sedimentation - answer Settling and deposition of
soil particles transported by wind & water.
Physical implications of erosion - answer Reduced
capacity
Increased flooding
increased maintenance
increased water treatment costs
Erosion - answer action of soil particles being
physically removed from surface and transported
away
