Abstract The main objective of this paper is to analyze the impact climate change on water resources management and groundwater quantity quality in coastal agricultural Almyros Basin, Greece. Intensive abstractions for irrigation nitrogen fertilization crop production maximization, have caused a large deficit, nitrate pollution, as well seawater intrusion aquifer system. Multi-model projections...

Coastal delta plains are areas with high agricultural potential for the Mediterranean region because of their soil fertility, but they also constitute fragile systems in terms water resources management interaction underlying aquifers sea. Such a case is Pinios River plain located central Greece, which constitutes significant ecosystem. Soil and Water Assessment Tool (SWAT) SEAWAT models were c...

Abstract A large tank (1.4 m x 4.0 1.3 m) filled with medium-coarse sand was employed to measure evaporation rates from shallow groundwater at controlled laboratory conditions, determine drivers and mechanisms. To monitor the level drawdown 12 piezometers were installed in a semi regular grid equipped high precision water level, temperature, electrical conductivity (EC) probes. In each piezomet...

Groundwater contamination due to saltwater intrusion (SWI) has an extreme effect on freshwater quality. Analytical and numerical models could be used investigate SWI. This study aims develop analytical solution SWI into coastal aquifers which was applied a real case at the Middle Nile Delta aquifer (MNDA). The presented new formula predict difference in depth of seawater interface change bounda...

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...

Nanotechnologies have been proposed for a variety of environmental applications, including subsurface characterization, enhanced oil recovery, and in situ contaminant remediation. For such applications, quantitative predictive models will be of great utility for system design and implementation. Electrolyte chemistry, which can vary substantially within subsurface pore waters, has been shown to...

freshwater lens on small islands may easily be overexploited or polluted due to overdrafts of fresh water by pumping which causes drawdown of the water table a rise or up-coning of the saltwater interface. present study is concerned with using a three-dimensional finite-difference numerical model to simulate the groundwater flow and transport model to predict the behavior of groundwater system ...

Laura Island, which is located about 50 km away from downtown, is a source of water supply in Majuro atoll, which is the capital of the Republic of the Marshall Islands. Low and flat Majuro atoll has neither river nor lake. It is very important for Majuro atoll to ensure the conservation of its water resources. However, upconing, which is the process of partial rising of the freshwater-saltwate...

Salt wedges divide coastal groundwater flow regime into two distinct regions that include a freshwater region above the saltwater-freshwater interface and a saltwater region below the interface. Several recent studies have investigated saltwater transport in coastal aquifers and the associated flow and mixing processes. Most of these studies, however, have either focused on studying the movemen...
