Certified Floodplain Manager | Exam Set 3 Questions and Answers
with 100% Correct Answers | Latest Version
Question 1.
The 1% chance/year flood. The base or min. flood elevation standard that commu- nities
must adopt in their local programs.
Correct Answer: Base Flood
Question 2.
Floodplain
Correct Answer: Floodway + floodway fringe; area subject to 1% chance flood
Question 3.
Channel of river and the adjacent area that must be reserved open space; an engineering
construct; provides for discharge of base flood
Correct Answer: floodway
Question 4.
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
Correct Answer: flood fringe
Question 5.
Parts 59, 60, 65, and 70 relate to the NFIP. "Emergency Management & Assistance" Title
44 of the Code of Federal Regulations.
Correct Answer: 44 CFR
Question 6.
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
Correct Answer: alluvial fan (flooding)
Question 7.
FIS
Correct Answer: Flood Insurance Study
, Question 8.
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map provided the community and is eventually superceded by a FIRM
Correct Answer: FHBM
Question 9.
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.
Correct Answer: FBFM
Question 10.
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.
Correct Answer: Levees
Question 11.
Closed basin lakes, uncertain flow paths, dam breaks, ice jams, and mudflows are the most
common types found in the US.
Correct Answer: Special Flood Hazards
Question 12.
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.
Correct Answer: Closed basin lakes
Question 13.
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.
Correct Answer: Uncertain flow paths
Question 14.
When a channel is lowered/flattened. Caused by erosion and sedimentation.
