FDEP Certification Program Study Guide
With 100% Verified Solutions
Chapter 1
Erosion CORRECT ANSWERS The process by which the land surface is worn away by
the action of wind, water, and gravity
Sedimentation CORRECT ANSWERS Is the settling out of soil particles transported by
water and wind
Two classifications of soil erosion CORRECT ANSWERS 1. Wind erosion 2. Water
erosion
Two classifications of water erosion CORRECT ANSWERS 1. Overland 2. Stream
Overland erosion CORRECT ANSWERS Occurs on denuded slopes when raindrops
splash and run off
Stream channel erosion CORRECT ANSWERS Occurs as the volume and velocity of
flow increases sufficiently to cause the movement of the streambed and bank materials.
Four proccesses of Overland erosion CORRECT ANSWERS 1. Splash or raindrop -
results when raindrops dislodge soil particles as splash them into the air.
2. Sheet erosion - caused by shallow sheets of water flowing off the land.
3. Rill erosion - develops as the shallow surface flow begins to concentrate in low spots
4. Gully erosion - occurs as the flow in rolls comes together in larger and larger
channels.
The major difference between gully and rill erosion CORRECT ANSWERS Size
Physical effects of erosion and sedimentation: CORRECT ANSWERS 1. Increased
flooding
2.reduced hydraulic capacity in rivers streams channelS reservoirs
3. Increased maintenance of storm water system
4 increased water treatment costs
5. Decreased recreational value
Biological effects of erosion and sedimentation: CORRECT ANSWERS 1. Reduces light
for aquatic plants
2. Clogs fish gills
3. Impairs spawning
4. Disrupts food chains
5. Blankets bottom, suppresses aquatic life
6. Disrupts ecosystem
, Planning the development to fit the terrain using particulars of the site: CORRECT
ANSWERS 1. Topography
2. Soils
3. Drainage patterns
4. Natural vegetation
Minimize the [EXTENT] of the area exposed at one time and the [DURATION] of
exposure CORRECT ANSWERS [extent, duration]
Apply [PERIMETER CONTROL]practices to protect the disturbed area from off site run
off and to protect off site areas from sediment damage CORRECT ANSWERS
[perimeter control]
Apply [EROSION CONTROL] practices to prevent excessive on site damage
CORRECT ANSWERS [erosion control]
Stabilize disturbed areas [IMMEDIATELY] after final grading CORRECT ANSWERS
[immediately]
Keep runoff velocities [LOW] and [RETAIN] runoff on the site CORRECT ANSWERS
[Low, retain]
Implement a thorough [MAINTENANCE] and [FOLLOW UP] (inspection) program.
CORRECT ANSWERS [maintenance, follow up]
Chapter 2
Soil particles smaller than .002 mm are classified as [CLAY] and [MUCK]and are two of
the soil types that cause the most erosion/turbidity problems in Florida CORRECT
ANSWERS [clay, muck]
Soils in the TYPE A hydrologic group have [HIGH] infiltration rates and [LOW] runoff
potential even when thoroughly wetted CORRECT ANSWERS [high, low]
[THE RAINFALL EROSION INDEX] is the only factor in the Universal Soil Loss
Equation which is beyond the developer's control. CORRECT ANSWERS [the rainfall
erosion index]
[SLOPE LENGTH and GRADIENT] and [COVER FACTOR] are the factors most easily
manipulated by the developer. CORRECT ANSWERS [slope length & gradient, cover
factor]
Chapter 3
Florida's ERP (Environmental Resource Permit) integrate [STORMWATER QUANTITY
& Quality , as well as Wetland Preservation requirements into a single permit.]
