Abstract

Excessive exploration of groundwater causes Seawater Intrusion (SWI) in coastal aquifers. The purpose of this study is to investigate the effect of aquifer bed slope on SWI characteristics including salt wedge Toe Position, thickness of mixing zone and seawater volume in the aquifer. Different scenarios under various bed slopes and directions were defined and numerical dispersive SEAWAT code was used for modeling. Two different boundary conditions (i. e. constant head and constant flux) were also applied to freshwater inflow at landside. The simulation results demonstrated that in the confined aquifers with landside constant flux, the SWI extent and thickness of mixing zone have increased when the slope changes from a positive value (i. e. longitudinal slope toward the sea) to negative amount (i. e. longitudinal slope toward the land). The results of this study showed that when the aquifer bed is considered flat, the SWI specifications including salt wedge Toe Position, Mixing Zone Thickness at bed and saline water volume were lower than in cases with negative slope and higher than in cases with positive slope. Type of freshwater inflow at land boundary also influenced the results. In confined aquifers, when land boundary condition was changed from constant flux to constant head, salt wedge characteristics were not significantly changed. Finally, variation in the aquifer bed slope affect the gravity factor (potential head) in the related equations accompanied with pressure head. This plays a key role on SWI specifications in Confined Coastal Aquifers.
