HYDROGEOLOGY EXAM 1 STUDY
GUIDE GROUNDWATER FLOW
AQUIFERS DARCYS LAW PRACTICE
QUESTIONS AND ANSWERS
how can we determine the temperature of shallow
groundwater? - CORRECT ANSWERS -look at mean
annual air temperature above land; variation is
minimal
,polarity - CORRECT ANSWERS -uneven distribution
of charges within a molecule resulting in slight
charges on either side of the structure
7 results of polarity on water - CORRECT ANSWERS -
High density
Thermal expansion ability (volume varies with
temperature)
High surface tension
High heat capacity
Low viscosity - flows easily
Low compressibility - not easily compressed
Strong solvent capability
,pressure head - CORRECT ANSWERS -height to
which a column of liquid with a density r will rise in
a piezometer (or manometer) as a result of a given
pressure at the measurement point
piezometric surface - CORRECT ANSWERS -
equipotential height to which water would rise in a
well
In life, why doesn't the water rise to the elevation of
head at the recharge area (like what happens in a u-
tube)? - CORRECT ANSWERS -frictional energy loss
, consolidation - CORRECT ANSWERS -when the
weight of an object increases pore fluid pressure,
then the water flows to an area of lower head and the
grains rearrange and settle
consolidation mag and rate in sand vs clay -
CORRECT ANSWERS -sand = less overall settlement,
quick
clay = more overall settlement, slow
settlement in deltas - CORRECT ANSWERS -layers of
sediment add weight to layers below and compact
them
