SECTION 1: FLOODS AND FLOODPLAIN MANAGEMENT (UNIT 1) (30 QUESTIONS)
1. What are the three most common types of flooding?
A) Riverine, coastal, and shallow
B) Flash, urban, and dam break
C) Riverine, flash, and storm surge
D) Coastal, lake, and ponding
Rationale: The three most common types of flooding are riverine, coastal, and shallow flooding.
These categories cover the majority of flood events encountered in floodplain management.
2. Which type of flooding has accounted for the most flood-related deaths in recent history?
A) Coastal flooding
B) Riverine flooding
C) Flash flooding
D) Shallow flooding
Rationale: Flash flooding has historically been responsible for the most flood-related fatalities
due to its rapid onset and high velocity.
3. What is a meander?
A) A curve or turn in a river channel
B) A type of flood control structure
C) A measure of flood velocity
D) A watershed boundary
Rationale: A meander is a curve or bend in a river channel that develops naturally over time as
the river erodes and deposits sediment.

4. What is the major cause of coastal flooding?
A) Storm surge
B) River overflow
C) Ice jams
D) Ponding
Rationale: Storm surge is the primary cause of coastal flooding, occurring when strong winds
push ocean water toward the shore.
5. What causes a tsunami?
A) Underwater earthquakes or volcanoes
B) Strong coastal winds
C) Heavy rainfall
D) Melting snowpack
Rationale: Tsunamis are typically triggered by underwater earthquakes, volcanic eruptions, or
landslides that displace large volumes of water.
6. List the five types of special flood hazards covered in FEMA 480.
A) Closed basin lakes, uncertain flow paths, dam breaks, ice jams, mudflows
B) Riverine, coastal, shallow, urban, flash
C) Storm surge, tsunami, erosion, subsidence, sinkholes
D) Floodway, flood fringe, floodplain, watershed, catchment
Rationale: The five special flood hazards are closed basin lakes, uncertain flow paths, dam
breaks, ice jams, and mudflows.
7. What is a watershed?
A) Also termed a basin or catchment area; the area that drains into a body of water
B) A flood control reservoir
C) A type of floodplain
D) A regulatory boundary
Rationale: A watershed (also called a basin or catchment area) is the land area that drains
precipitation and surface runoff into a common outlet.

8. What is a floodplain?
A) The area adjacent to a watercourse that is subject to flooding
B) A flood control structure
C) A regulatory zone
D) A type of insurance policy
Rationale: A floodplain is the land area adjacent to a river, stream, lake, or coast that is
susceptible to flooding.
9. What are natural and beneficial floodplain functions?
A) Natural flood and erosion control, biologic resources, and societal resources
B) Only flood control
C) Only habitat preservation
D) Only recreational use
Rationale: Floodplains provide natural flood and erosion control, support biologic resources,
and offer societal resources such as recreation and water quality improvement.
10. What are the two problems that result from floodplain development?
A) Sediment and contaminants
B) Increased property values and tourism
C) Reduced flood risk and improved drainage
D) Enhanced wetlands and wildlife habitat
Rationale: Floodplain development increases sediment and contaminant loads in waterways,
degrading water quality and habitat.
11. Water as little as how many feet deep can collapse the walls of a frame house?
A) 3 feet
B) 1 foot
C) 5 feet
D) 10 feet
Rationale: Water as little as 3 feet deep can exert enough pressure to collapse the walls of a
frame house.
