1. A coastal construction project in a high-wave energy environment
requires selection of foundation systems. Which option best minimizes
lateral load damage from wave impact and scour in a FEMA V-zone?
A. Shallow strip footing with masonry wall
B. Slab-on-grade foundation with compacted fill
C. Elevated pile foundation embedded deep into stable strata
D. Floating slab foundation without anchorage
Answer: C
Pile foundations transfer loads to deeper, more stable soil layers and
reduce exposure to scour and wave forces, making them most
suitable for V-zone coastal conditions.
2. Which phenomenon most directly causes structural undermining of
coastal foundations during storm surge events?
A. Capillary rise in soil
B. Hydraulic scour around foundation elements
C. Thermal expansion of concrete
, D. Wind-driven rain infiltration
Answer: B
Scour removes supporting soil around foundations due to fast-
moving water, significantly reducing structural stability during storm
surge conditions.
3. In coastal engineering, what is the primary function of riprap placed
along shorelines?
A. Increase soil salinity for vegetation growth
B. Absorb and dissipate wave energy to reduce erosion
C. Increase hydrostatic pressure on retaining walls
D. Accelerate sediment transport offshore
Answer: B
Riprap consists of large stones that break wave energy and reduce
shoreline erosion by dissipating hydraulic forces.
4. Which building code consideration is most critical when designing
structures in coastal flood hazard areas?
A. Interior room layout efficiency
B. Resistance to termite infestation
C. Base flood elevation (BFE) compliance
D. Paint color durability in salt air
Answer: C
Base Flood Elevation determines the minimum height above
expected flood levels, ensuring structures are protected from
inundation.
5. What is the primary purpose of geotextile fabric in coastal
construction applications?
A. Increase concrete curing speed
B. Provide filtration and soil stabilization while allowing water flow
C. Act as primary load-bearing structural support
, D. Replace drainage systems entirely
Answer: B
Geotextiles separate soil layers while permitting water movement,
reducing erosion and improving soil stability.
6. Which coastal zone is most vulnerable to wave velocity and breaking
wave forces?
A. Inland floodplain zone
B. A-zone
C. V-zone (Velocity zone)
D. Non-hazard upland zone
Answer: C
V-zones experience direct wave impact and high-velocity flood forces,
requiring specialized structural design requirements.
7. What is the primary environmental risk associated with seawall
construction?
A. Increased groundwater recharge inland
B. Down-drift shoreline erosion due to wave reflection
C. Reduction of tidal amplitude
D. Increased vegetation growth at shoreline
Answer: B
Seawalls reflect wave energy, often intensifying erosion on adjacent
shorelines by altering sediment transport patterns.
8. Which soil condition presents the greatest risk for coastal foundation
settlement?
A. Dense gravel with low moisture content
B. Overconsolidated clay with low permeability
C. Loose, saturated sandy soil
D. Cement-stabilized fill
Answer: C
, Loose saturated sand is highly susceptible to liquefaction and
settlement under wave and seismic loading.
9. What is the main objective of a breakwater structure?
A. Increase tidal currents near shoreline
B. Reduce wave energy before it reaches the shore
C. Accelerate sediment erosion offshore
D. Increase saltwater intrusion inland
Answer: B
Breakwaters are offshore structures designed to absorb wave energy
and protect coastal areas from direct wave impact.
10. Which force is most responsible for uplift on coastal buildings
during storm surge?
A. Hydrostatic buoyancy pressure
B. Gravitational soil compaction
C. Capillary adhesion
D. Thermal convection currents
Answer: A
Floodwater creates buoyant uplift forces that can lift or displace
improperly anchored structures.
11. In coastal construction, what is the purpose of pile driving
deeper than estimated scour depth?
A. Reduce construction cost
B. Ensure foundation stability after erosion occurs
C. Increase soil permeability
D. Promote vegetation growth
Answer: B
Driving piles below predicted scour depth ensures the foundation
remains stable even after surrounding soil is eroded.
