Abstraction, 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 کاملCoastal 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 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 کاملSeawater intrusion in coastal aquifers: Effects of seasonal variations in extraction and recharge rates
Over-exploitation of coastal aquifers causes seawater intrusion and eventually contamination of groundwater wells in many parts of the world. Artificial recharge of treated wastewater can be used to avoid or control seawater intrusion. A common characteristic of many coastal areas in Southern Europe is that most of the annual water demand, and hence the amount of water that can be used for arti...
متن کاملMonitoring of Seawater Intrusion in Coastal Aquifers: Basics and Local Concerns
Monitoring of seawater intrusion is essential to determine and predict groundwater deterioration, and assess other managerial activities in coastal aquifers. Monitoring involves designing strategy and methodology of field surveys for choosing the most effective means towards obtaining the most reliable possible data. The monitoring of seawater intrusion may consist of direct and indirect method...
