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

-waste disposal is a problem for the individual workers and some subcontractors, but it's
no big deal - -false
-truck washing should be done in designated area, not near the perimeter controls - -true
-storage paints, solvents, cements, pesticides, acids, or other potentially polluting
chemicals is no big deal because they are only stored temporarily and get used up quickly -
-false
-the public needs to understand that dust is just a normal part of construction - -false
