2. Uncertain flow paths
3. Dam breaks
4. Ice jams
5. Mudflows
,What two problems result from floodplain development? Correct
Answer 1. Development alters the floodplain and the dynamics of
flooding
2. Buildings and infrastructure are damaged by periodic flooding.
What does watershed development do to flooding? Correct
Answer The increase in impervious surface results in increased
runoff and higher flood levels.
What is one of the problems with constructing seawalls to protect
buildings from flooding or erosion? Correct Answer It can
accelerate erosion on properties at the end of the wall.
What are the five main causes of flood damage? Correct Answer
1. Hydrodynamic forces
2. Debris impact
3. Hydrostatic forces
4. Soaking
5. Sediments and contaminants
Standing water as little as _____ feet deep can collapse the walls
of a frame house. Correct Answer 3 feet
,What are some of the safety and health hazards that accompany
floods? Correct Answer 1. Disruption of public utilities
2. Electrocution
3. Contamination of water supplies
4. Fire

breeding grounds for germs and mosquitoes
6. Mold, mildew, and bacteria that grow in damp, flooded areas
7. Contaminated air from dirty heating ducts

What is the Unified National Program for Floodplain
Management's definition of "floodplain management"? Correct
Answer "A decision-making process that aims to achieve the wise
use of the nation's floodplains"
What are the two primary goals of floodplain management?
Correct Answer 1. To reduce the loss of life, disruption, and
damage caused by floods
2. To preserve and restore the natural resources and functions of
floodplains
, What areas are conductive to flash flooding? Correct Answer 1.
Hilly area with steep slopes and narrow valleys
2. Urban areas with large amounts of impervious surfaces and
storm sewers
3. Area downstream of dams or subject to ice jams
Is erosion only a threat in coastal areas? Correct Answer No.
Riverine erosion can move stream channels and undercut
structures.
What is ponding? Correct Answer Where stormwater runoff
collects in depressions and cannot drain out.
Are plants and animals the only beneficiaries of the "natural and
beneficial functions" of floodplains? Correct Answer No. People
benefit from floodplains through the food they provide, the
recreational opportunities they afford, and the scientific
knowledge gained in studying them. Floodplains also recharge
groundwater supplies and their filtering actions help improve
water quality.
What does filling in a floodplain do? Correct Answer Filling
reduces the floodplain's ability to store excess water, sending
more water downstream and causing floods to rise to higher
levels.
