9) Fens

Question 13

lacustrine wetland

Answer 13

• wetland associated with standing water bodies such as ponds lakes and reservoirs. - low salt content
• plant cover less than 30%

Question 14

Riparian wetland

Answer 14

• Adjacent to rivers
• Periodic and often have short inundation
• Common in braided rivers
• dominated by plant material

Question 15

Estuarine wetland

Answer 15

• tidal wetlands, low-wave energy environments
• 0.5-30 ppt salinity
• persistant emergent vegetation

Question 16

Palustrine wetland

Answer 16

Palustrine comes from the Latin word palus or marsh . Wetlands within this category include inland marshes and swamps as well as bogs , fens , tundra and floodplains . Palustrine systems include any inland wetland which lacks flowing water, contains ocean-derived salts in concentrations of less than 0.05%, and is non- tidal .

Question 17

palustrine wetland

Answer 17

• relating to a system of inland, non tidal wetlands characterized by the presence of trees, shrubs, and emergent vegetation (rooted below water but growing above surface)
• range from permanently saturated or flooded land (as in marshes, swamps, and lake shores) to land that is wet only seasonally (as in vernal pools)

Question 18

Palustrine

Answer 18

Wetlands dominated by vegetation (marsh, swamp, bog, fen, prairie wetlands)

Question 19

Lacustrine

Answer 19

Of or related to lakes

Question 20

fen

Answer 20

• groundwater fed, dominated by peat moss, rich in mineral salts, alkaline
• low land covered wholly or partially with water; marsh; boggy land

Question 21

bog

Answer 21

• wet, spongy ground with soil composed mainly of decayed vegetable matter
• same as fen but acidic

Question 22

salt marsh

Answer 22

transitional intertidal habitats that occupy the interface between land and either brackish or slaty water sediment

Question 23

magrove swamps

Answer 23

• roots submerged in water

* saltwater or brackish

Question 24

brackish

Answer 24

1. made up of a mixture of fresh water and seawater

2. having an unpleasant taste

Question 25

meadow

Answer 25

• field primarily vegetated with grasses

* wet only part of the year

Question 26

Urban sprawl

Answer 26

follows a linear path from city to suburbs usually popping up off one main linear highway

Question 27

Traffic Calming Measures

Answer 27

1. speed bumps
2. chicanes
3. narrowing of the road
4. small corner radii
5. related street elements like lighting/traffic circles

Question 28

traffic calming

Answer 28

create an environment that signals (consciously and subconsciously) drivers to slow down and drive as if they are in downtown/pedestrian walkways

Question 29

planting strip

Answer 29

• area of the streets cape that provides ped/car buffer
• beautifies street
• allows for utility corridor

Question 30

Noise Mitigation

Answer 30

• Vegetation
• Solid barriers (walls, builings, earth berms, hills)
• Land use controls (most effective)

Question 31

nuisance

Answer 31

• interferes w/ ones right to quiet enjoyment

* may include airports, lots of billboards, power lines, water towers

Question 32

angle of incidence

Answer 32

angle at which the suns rays strike the earth

Question 33

Azimuth

Answer 33

Direction around the horizon from due north, measured clockwise in degrees. For example, the azimuth of due north is 0 degrees, due east is 90 degrees, due south is 180 degrees, and due west is 270 degrees

Question 34

Albedo

Answer 34

• a measurement used to determine the reflectivity of an objects surface; it states how much solar energy is reflected from the object back into space.
• n. the proportion of incident radiation reflected by a surface

Question 35

bioretention pond

Answer 35

• structural stormwater control designed to filter pollutants from water using vegetation
• only allow for overflow water to drain into pipes
• best for smaller sites with a gentle slope and a low water table to prevent contamination
