Erosion and Sediment Control Plan Test
With Complete Solutions
Soil Erosion CORRECT ANSWERS process of detachment and transport of sediment
particles caused by wind, rain, ice, and gravity
Erosion rates directly correspond to? CORRECT ANSWERS the percentage of bare soil
on a site
What are potential problems arising from construction related activities? CORRECT
ANSWERS -degradation to downstream properties and waterways
-damage to new and existing infrastructure
