Abstract
This editorial presents a representative collection of 11 papers presented in the Special Issue on Seawater Intrusion into coastal aquifers. Coastal aquifers are one of the most important water resources in the world. In addition, the natural discharge of freshwater to the sea as submarine groundwater discharge (SGD) has an important role in the ecology of marine environments. The dynamics of seawater and freshwater within coastal aquifers are highly sensitive to disturbances, and their inappropriate management may lead to the deterioration of water quality. In many coastal aquifers, seawater intrusion has become the major constraint imposed on groundwater utilization. Groundwater exploitation and climate variations create dynamic conditions, which can significantly increase seawater intrusion into aquifers and may result in the salinization of wells.

El Hamidi et al [1] numerically simulate the effects of climate changes, over pumping, and sea-level rise on seawater intrusion in northern Morocco
Based on vertical pressure differences, Mor et al [2] developed a densitometer for monitoring density in hypersaline bodies
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. El Hamidi et al [1] numerically simulate the effects of climate changes, over pumping, and sea-level rise on seawater intrusion in northern Morocco. They predict that a significant part of the aquifer will be salinized by 2040. Desalination plants, recycled water, and artificial aquifer recharge are suggested to improve the predicted results.
