CERTIFIED FLOODPLAIN MANAGER
CERTIFICATION EVALUATION TESTED
QUESTIONS AND ANSWERS COMPLETE
REVIEW
●● Floodplain
Answer: Floodway + floodway fringe; area subject to 1% chance flood
●● floodway
Answer: Channel of river and the adjacent area that must be reserved
open space; an engineering construct; provides for discharge of base
flood
●● flood fringe
Answer: the fringe or backwater areas of a flood that store nearly still
water during a flood and gradually release it downstream after the flood;
development may be allowed here
●● 44 CFR
Answer: Parts 59, 60, 65, and 70 relate to the NFIP. "Emergency
Management & Assistance" Title 44 of the Code of Federal Regulations.
●● alluvial fan (flooding)
,Answer: A fan-shaped deposit of sediment formed when a stream's slope
is abruptly reduced (hence flow path of stream becomes unpredictable,
resulting in flooding **characterized by:** 1) high velocity flows; 2)
active erosion and sedimentation; 3) unpredictable flow paths
●● FIS
Answer: Flood Insurance Study
●● FHBM
Answer: Flood Hazard Boundary Map. An official map of a community
published by FEMA that delineates the approximate boundary of the
floodplain. An FHBM is generally the initial map provided the
community and is eventually superceded by a FIRM
●● FBFM
Answer: Flood Boundary Floodway Map. An official map of a
community, on which FEMA has delineated the regulatory floodway.
Recent FISs show the floodway on the FIRM and do not include an
FBFM.
●● Levees
Answer: An embankment designed to manage a certain amount of
floodwater and can be overtopped or fail during flood events exceeding
the level for which they were designed; typically built parallel to a
waterway to reduce the risk of flooding on the landward side.
, ●● Special Flood Hazards
Answer: Closed basin lakes, uncertain flow paths, dam breaks, ice jams,
and mudflows are the most common types found in the US.
●● Closed basin lakes
Answer: Two types: no outlets like Great Salt Lake, or irregular outlets
like the Great Lakes; either way == large fluctuations in water surface
elevation & low drainage rates. Septic fields are unusable. Waves may
be experienced. A type of special flood hazard.
●● Uncertain flow paths
Answer: Ex: *alluvial fan* = a fan-shaped area at the base of a valley
where the slope of a mountain flattens out, the high-velocity floodwater
decreases in speed and spreads out like in a **sheet flow** dropping
sediment and rock. May have multiple, undefined channels. Common in
mountainous areas with less ground cover and more opportunity for
erosion. *Poses 3 hazards: (1) velocity of water/debris, (2)
sedimentation, (3) migrating channels
Ex: *moveable stream bed* = when high velocity flood runs through an
area with loose sand or soil, the erosion and sedimentation can occur
rapidly and cause channel degradation, aggravation, and/or migration.
●● Channel degradation
Answer: When a channel is lowered/flattened. Caused by erosion and
sedimentation.
