Types of floodplains - answerRiverine, coastal, and shallow
Watershed - answerarea that drains into a lake, stream, or body of water. Also
called basin or catchment area.
Channel - answerGround features that carry water through and out of a watershed
Riverine Flooding - answerflooding that occurs along a channel
Flash flooding - answerflooding that occurs in hilly and mountainous areas that
may come scant minutes after a heavy rainfall. One can also occur in urban areas
where pavements and drainage improvements speed runoff to a stream.
Overbank Flooding - answerThe most common type flooding in the US. It occurs
when downstream channels receive more rain or snowmelt than normal, or a
channel is blocked by ice or debris. Excess water overloads the channels and flows
out onto the floodplain
Velocity - answerOne measure of a flood is the speed of moving water. Measured
in feet per second
,Thalweg - answerThe channel bottom
Meander - answera curve in the channel. The outside bank of the meander is
subject to erosion, the inside bank is subject to deposits
Accrete - answerto build up a shoreline by depositing sand, either by nature or
human actions
Actual Cash Value - answerThe replacement cost for a building, minus a
depreciation percentage based on age and condition.
Alluvial Fan - answerAn area at the base of a valley where the slope flattens out,
allowing the floodwater to decrease in speed and spread out, dropping sediment
and rock over a fan-shaped area.
Amendment - answerA change to a FEMA floodplain map that removes an area
that was inadvertently included in the Special Flood Hazard Area
Approximate studies - answerFlood hazard mapping done using approximate study
methods that show the approximate outline of the base floodplain. An approximate
study does not produce a base flood elevation.

used for shallow flooding
, Basement - answerAny area of the building having its flood subgrade (below
ground level) on all sides
Base floodplain - answerthe area of water and land inundated by the base flood

Bench marks - answerMonuments on the ground that show the elevation of the
spot above sea level. Also called Elevation Reference Marks.
Building - answerA walled and roofed structure including a gas or liquid storage
tank that is principally above ground as well as a manufactured home. Also known
as structure
Building Condition Survey - answerA windshield survey conducted to obtain a
preliminary evaluation of the extent and severity of damage to buildings after a
disaster
CAP - answerCommunity Assistance Program
Cfs - answercubic feet per second, the unit by which discharges are measured (A
cubic foot of water is about 7.5 gallons)
CLOMA - answerConditional Letter of Map Amendment
