Two infinitely long rivers flow north-south and are connected in the subsurface by a confined aquifer. The distance between the rivers is 250 m. The aquifer is 10 m thick (b) with permeability of 1x10-11 m2 . The aquifer is overlain and underlain by clay layers that have a permeability of 1x10-19 m2. The average elevation of the western river is 200 m above sea level and the average elevation of the eastern river is 150 m above sea level. a. derive an equation for the water table elevation in the aquifer b. make a plot (in excel or on paper) of the water table elevation between the two rivers

Transcribed Image Text:Two infinitely long rivers flow north-south
and are connected in the subsurface by a
confined aquifer. The distance between the
rivers is 250 m. The aquifer is 10 m thick (b)
with permeability of 1x10-11 m2. The
aquifer is overlain and underlain by clay
layers that have a permeability of 1x10-19
m2. The average elevation of the western
river is 200 m above sea level and the
average elevation of the eastern river is 150
m above sea level.
a. derive an equation for the water table
elevation in the aquifer
b. make a plot (in excel or on paper) of the
water table elevation between the two
rivers
C. what is the flux from the western river to
the eastern river?
d. list any assumptions/approximations that
you make
