Tidal Effects on Coasts
How does coastal tidal action affect the water levels in
surficial aquifer wells close to the seashore?
Is there any literature
this subject available?
In my area there is a 5-8 foot difference
low and high tides depending upon the month. Would this make the surface
of water in shallow wells respond up and down in a corresponding manner?
Thanks for your help, Rebekah
There would be a change in the hydrostatic head pressure if the aquifer and
the sea water were connected somehow underground and that could cause the
water level in surface wells. However, since the well water is not salty
[presumably] there must be impermeable strata of some kind of rock
separating the well water from the sea water.
