ECOL 1000 EXAM 2 - UGA
CONNELLY
where is much of GA getting their water? - ANSWERS-ACT and
ACF River Basins in GA
how to solve water shortage in GA? - ANSWERS-damming rivers
and creating reservoirs (lake lanier)
benefits of dams - ANSWERS--source of freshwater
-flood control
-electricity production
-boating, fishing, recreation
downsides of dams - ANSWERS--enormous potential for
evaporation, especially during summer when we need water the most
tri-state war - ANSWERS-georgia, alabama, and florida fight over
water
tri-state war: GA - ANSWERS-upstream user
-wants to have enough water to continue growing around Atlanta
,tri-state war: BAMA - ANSWERS-downstream user
-concerned that GA increasing need for water will limit their use for
power generating and fisheries
tri-state war: FL - ANSWERS-downstream user
-wants enough freshwater to reach the Apalachicola bay to support its
multimillion dollar shellfish industry
conserving water - ANSWERS-new technology and behavior change
-ex. shower, tech: low flow shower head, behavior: water doesn't
always have to be running
Balancing our Water Budget in Georgia - ANSWERS-Increase
reserves?
Reduce withdrawals
Conservation
Recycling (grey water)
Landscape architecture
point source pollution - ANSWERS-some industrial and agricultural
sources of discharge pollutants directly
non-point source pollution - ANSWERS-a variety of sources
contributes pollutants that can run off the surface of land during
rainfall and enter water
, deadzone - ANSWERS-excess nitrogen from any rivers and streams
within the watershed will eventually flow to a larger body of water
(Gulf of Mexico)
-excess nutrients
-hypoxic (water contains less than two parts per million of dissolved
oxygen)
-organisms unable to survive
riparian area - ANSWERS-plot of land adjacent to a body of water
that is affected by the water's presence and that affect the water itself
conservation of riparian areas - ANSWERS--plants are nutrient sinks:
they store nutrients in their tissues, reducing the amount free to enter
the water
-plant roots stabilize banks and prevent erosion and the deepening of
the channel, which can speed water flow and lead to further erosion
-ground vegetation slows runoff and allows water to soak into ground.
this keeps the water and any pollutants it may carry out of the stream
and increases infiltration, which replenishes groundwater
-shade provided by overhanging trees cools the water, important
because cooler water can hold more oxygen
-trees provide food: leaf litter that falls in the water is a main nutrient
source for aquatic organisms
clean water act in 1972 - ANSWERS-established pollution standards
and set in motion establishment of best management practices to
reduce aquatic pollution
