FSESCI Comprehensive Review
Chapter 1
Erosion - ✔✔ correct answer is the process by which the land surface is wornaway by the action of
wind, water, and gravity
Sedimentation - ✔✔ correct answer is the settling out of soil particlestransported by water and wind
Soil erosion can be classified as ..... erosion or ...... erosion, and the sources can be ether ...... or ........
- ✔✔ correct answer wind; water; natural; manmade
Water erosion can be classified as either ...... erosion or ....... and ....... erosion - ✔✔ correct answer
overland; stream; channel
Four processes of overland erosion are: - ✔✔ correct answer Splash or rain drop erosion, sheet
erosion, rill erosion, and gully erosion.
Four principle factors influencing soil erosion are: - ✔✔ correct answer Soil characteristics;
Vegetative cover; Topography; Climate
List three physical effects of erosion and sedimentation: - ✔✔ correct answer Increased flooding.•
Reduced hydraulic capacity in rivers, streams, channels,reservoirs.• Increased maintenance of
stormwater systems.• Increased water treatment costs.• Decreased recreational value.Chapter 1 -
Review
List three biological effects of erosion and sedimentation: - ✔✔ correct answer Reduced light for
aquaticplants; Clogs fish gills; Impairs spawning; Disrupts food chain
Planning the development to fit the terrain using the particular: - ✔✔ correct answer Topography;
Soils; Drainage patterns; Natural vegetation of the site; Minimize the extent of the area exposed at
one time andthe duration of exposure
Apply ........ practices to protect the disturbed area from off-site runoff and to protect off-site areas
from sediment damage - ✔✔ correct answer Perimeter control
Apply ........ practices to prevent excessive on-site damage - ✔✔ correct answer Erosion control
