Coastal Erosion Due to Seawater Intrusion into Groundwater Aquifers
Problem Statement: In general, the drinking water systems sourced from ground water (GW) contains chemicals at double the current maximum contaminant levels (MCL) of colloids. However, due to increasing demand of water, groundwater may be subjected to over-exploitation and the natural equilibrium is thus disturbed. A steady-state condition is established between seawater and freshwater in a coa...
متن کاملAbstraction, desalination and recharge method to control seawater intrusion into unconfined coastal aquifers
In this study, abstraction, desalination and recharge method and SEAWAT numerical model are used to investigate seawater intrusion repulsion in a hypothetical two-dimensional coastal aquifer to understand the relation of seawater intrusion with abstraction, desalination and recharge parameters (i.e. abstraction/recharge rate, wells distance and depth). Abstraction, desalination and recharge con...
متن کاملDevelopment of a groundwater quality index for seawater intrusion in coastal aquifers
Coastal aquifers are increasingly threatened by seawater intrusion due to increased urbanization, groundwater exploitation, and global sea-level rise. Pattern diagrams, which constitute the outcome of several hydro-geochemical processes, have traditionally been used to characterize vulnerability to seawater intrusion. However, the formats of such diagrams do not facilitate the geospatial analys...
متن کاملGroundwater withdrawal in randomly heterogeneous coastal aquifers
We analyze the combined effects of aquifer heterogeneity and pumping operations on seawater intrusion (SWI) in coastal aquifers, a phenomenon which is threatening Mediterranean and worldwide regions. We conceptualize the aquifer as a three-dimensional randomly heterogeneous porous medium, where the spatial distribution of permeability is uncertain. The geological setting of our study is pattern...
متن کاملPlanning groundwater development in coastal aquifers
This study examines an approach for planning groundwater development in coastal aquifers. The seawater intrusion is controlled through a series of barrier extraction wells. The multi-objective management problem is cast as a nonlinear, nonconvex combinatorial model and is solved using a coupled simulation–optimization approach. A density-dependent groundwater flow and transport model, SEAWAT is...
