underground water

Question 1

water table

Answer 1

• The upper layer of the phreatic
  zone.
• It was a rise and fall depending
  on the amount of rainfall
  percolating downwards and
  the amount of baseflow from
  lower rocks.
• seasonally wetted and seasonally dries

Question 2

aeration zone

Answer 2

is the subsurface zone between the ground surface and the water table where the pores in soil and rock contain both air and water.

The aeration zone is seasonally wetted and seasonally dries.

Question 3

ground water recharge occurs with:

Answer 3

~ infiltration {from precipitation}
~ seepage {through banks/beds
of rivers, lakes, puddles,
ditches}
~ leakage and inflow {from
adjacent rocks and aquifers}
~ artificially from irrigation or
reservoirs.

Question 4

inflow

Answer 4

movement of water into specific area.
EG- rivers, ground water systems.

Question 5

groundwater loss occurs with:

Answer 5

~ evapotranspiration {mainly in
low areas}
~ natural discharge {seepage
and spring flow}
~ leakage and outflow {into
aquicludes from aquifers}
~ artificial abstraction

Question 6

springs

Answer 6

water reaches the surface, making a spring. can be substantial enough to be a source. usually, when percolating water reaches an impermeable layer or the saturated zone

Question 7

water budget equation

Answer 7

S = P - Q - E

S = soil storage
P = precipitation
Q = channel flow
E = evapotranspiration
