摘要

This study is an effort to trace the implication of tidal fluctuation on coastal groundwater quality for different
aquifers in case of Saijo plain, western Japan, through major ion, heavy metal and isotopic chemistry as well
as to estimate aquifer parameters by tidal response method. Time series analysis for chemical characteristics
depicts that tidal fluctuation at diurnal basis significantly affects ionic signature of groundwater along with
piezometric level for unconfined aquifer whereas effect is less prominent for confined aquifer. Different
plots (e.g. 87Sr/86Sr vs 1/Sr and BEX vs Cl) were drawn in order to deduce mechanisms responsible for
water quality change with tidal phase and it was found that cations exchange and local sea water–fresh
water (SW–FW) mixing along with oxidation–reduction are likely to be main processes responsible for
water quality changes. Using tide aquifer interaction technique, calculated hydraulic conductivities for different
monitoring sites were 0.01 and 2.8×10−6 m/s which appropriately address geological properties of aquifers,
and thus it can be concluded that tide aquifer technique is a reliable technique to estimate aquifer
properties.
