Preface: Saltwater and freshwater interactions in coastal aquifers

Freshwater-saltwater motion in a coastal karstic aquifer -

The case study of the brackish spring of "Almyros of Heraklio" in Crete (Greece) and its vast carbonate coastal aquifer is presented, showing the consequence of preferential flows of continental fresh water and saline sea water in karst galleries in a coastal area. Flow heterogeneity generates unexpected upconing in boreholes, and permits the spring of Almyros not to be directly connected with ...

Laboratory study of the simultaneous effect of discharge well and cut of wall on reducing saltwater intrusion in coastal aquifers

These days, the sea level rising and excessive harvesting of coastal aquifers has caused the intrusion of saltwater into underground water sources. In this study, the performance of the use of cut of wall, discharge well, and their simultaneous use in preventing saltwater intrusion has been evaluated in a laboratory model and under different scenarios. The results show that the appropriate use ...

Stochastic Optimization for an Analytical Model of Saltwater Intrusion in Coastal Aquifers

The present study implements a stochastic optimization technique to optimally manage freshwater pumping from coastal aquifers. Our simulations utilize the well-known sharp interface model for saltwater intrusion in coastal aquifers together with its known analytical solution. The objective is to maximize the total volume of freshwater pumped by the wells from the aquifer while, at the same time...

Iron Reduction in Freshwater and Saltwater Environments

assessment of urmia lake water interactions and saltwater intrusion to surrounding aquifers

in the last decade, the water level of urmia lake has experienced a dramatically drop. although the causes of this lose have been investigated, the significance of groundwater supplies had not been concerned so much. in the present research, groundwater resources around the lake were explored as its water supplier. the number of wells and groundwater withdrawal has been increased because of cul...
