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 کاملManagement of aquifer recharge in Lebanon by removing seawater intrusion from coastal aquifers.
This study investigates the feasibility of management of aquifer recharge (MAR) in Lebanon by designing well barriers to remove seawater intrusion from the fractured carbonate aquifers. Groundwater flow and saltwater/freshwater 50% sharp interface have been modeled along the coastal area using the Ghyben-Herzberg theory. The groundwater flow simulations have been supported by field transmissivi...
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 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...
