Hydrologic cycle - answer The natural cycle that circulates water throughout the
environment to maintain an overall balance between water in the air, on the surface and
in the ground. Unit 1, Section A
Floodplain - answer Any land area susceptible to being inundated by flood waters from
any source. Unit 1, Section A
Riverine, Coastal and Shallow flooding - answer What are the 3 major categories
Flood - answer Sometimes the hydrologic cycle gets out of balance, sending more
water to an area than it can normally handle. The resulting is a______?
Watershed - answerAn area that drains into a lake, stream or other body of water. Unit
1, Section A.
Channels - answerDefined landforms that carry water. They may be called rivers,
creeks, streams or ditches. They can been wet all the time or dry most of the time.
Riverine Flooding - answerWhen a channel receive too much water, the excess flows
over its banks and into the adjacent floodplain. Flooding that occurs along a channel is
called_______?
Overbank Flooding - answerThe most common type of flooding in the United States is
called_________
Section 1 page 7.
Velocity - answerThe speed of moving water, that is measured in feet per second
Units one and two - answerTo be introduced to the kinds of floods common to
communities in United States, concepts behind floodplain management and the NFIP
,Unit Three - answerIn this unit you will learn about the various types of flood data
needed to administer a floodplain management program.
Unit Four - answerIn this unit discusses how to use data provided in NFIP studies and
maps
flash flooding - answerA flood that develops in a very short time. It is usually caused by
intense and heavy rain
Coastal flooding - answerDevelopment along the coast line, Gulf of Mexico, in large
lakes are exposed to two types of flooding in riverine areas. Coastal storms and coastal
erosions.
Tsunamis - answerThe Pacific and Caribbean coast face three problems Coastal storm,
coastal erosion and _____
Nor'easter - answerHurricanes and severe storms cause most coastal flooding. These
include, "_____"which are severe storms on the Atlantic coast with winds out of the
north east.
Storm surge - answerPersistent Highwinds and changes in the air pressure push water
towards the shore, causing a ________ which can raise the level of a large body of
water by several feet. Waves can be highly destructive as they move inland, battering
structures in their path.
Protection of inland development - answerWind and waves shape sand dunes, blocks
and barrier islands. Because these landforms provide natural buffers from the effects of
a storm, their preservation is important to this?
Accrete - answerTo build up a shoreline by depositing sand, either by nature or human
actions. Unit one, section 8.
Appendix D - answerKeywords and phrases appear with underlines and they are listed
in the glossary in___________
Emergency management Institute - answerThis study guide and desk reference is
based on a home study course that was developed through FEMA's "E.M.I." dated
March 1998. what does EMI stand for?
Flash Flooding - answerWhat type of flooding ranked first as the cause of flood related
deaths in United States.?
Thalweg - answerThe bottom of a river channel. Unit one, section A
Meander - answerA curve in a river. Unit one, section A
, Riverine erosion - answerProperties on the outside of curves face a double threat of
inundation and undercutting from ________ during floods. What kind of erosion?
Coastal erosion - answerLong-term __________Is another natural process that shapes
shorelines. It is a complex process that involves natural and human-induced factors.
The natural factors include sand sources, sand size and density, changes in water level,
and the affects of waves, currents, tide and wind. These factors determine whether a
shoreline will recede or accrete.
15 feet - answerAnother hazard along the coast is a tsunami, a large wave often called
a "tidal" wave even though tides and tsunami's are not related. Caused by an
underwater earthquake or volcano, a tsunami is a pressure wave that can raise water
levels as much as______
True— unit one page 11 - answerTrue or false? Tsunamis usually occur in the Pacific
ocean, but They have caused floods in the Caribbean. Because they can happen on a
clear day and are not related to storms, they can catch many people unaware.
True unit one page 11 - answerTrue or false?
Lake shores can flood in ways similar to ocean coast. Along the Great Lakes, severe
storms came produce waves and cause shoreline erosion. FEMA is starting to map
Great Lakes flooding with the same techniques it uses for ocean coastal flooding.
Sheet flow, ponding and urban drainage. - answerShallow flooding occurs in flat areas
where a lack of channels means water cannot drain away easily. Shallow flood
problems fall into three categories. What are those three categories.
Sheet flow Unit one page 11 - answerWhere there are inadequate or no defined
channels, floodwaters spread outs over a large area at a somewhat uniform depth in
what's called_____?
Ponding ——unit one page 12 - answerIn some flat areas, run ass collects in
depressions and cannot drain out, creating a _______effect.
Urban drainage - answerA ________system comprises the ditches, storm sewers,
retention ponds, and other facilities constructed to storm runoff or carry it to a receiving
stream, lake or the ocean. Other man-made features in such a system includes yards
and swells that collect runoff and direct it to the sewers and ditches.
Man-made features or systems - answerUrban drainage is created by channels that
have been built and pumps installed to mechanically move water pass the levee often
these _________systems do not have the capacity to handle heavy rains or intent
storms.
Closed basin Lakes, uncertain flow paths, dam brakes, ice jams and mudflows -
answerThe flooding types describe so far are the more common types found in the
