Development of the brackish karstic spring Almyros in Greece


  • Marko Breznik


In karstic massifs of anisotropic permeability groundvvater circulates practically, only through zones of high permeability called veins. Coastal springs are contaminated by sea-water either at the mouth of a submarine spring or inside the karstic massif in a branching of veins. The methods to desalinate brackish karstic spring are: - isolation of the karstic aquifer from sea-water intrusion by a dam at the spring or by a grout-curtain that seals the lower vein with sea-water; - interception of fresh-water by boreholes, wells or drainage galleries within the karstic massif, inland of the sea-water influence; - rise of the spring level by a dam. In that case, fresh-water accumulates in the karstic massif and prevents the intrusion of sea-water. There are already numerous cases of successful development of brackish springs. A more detailed analysis discusses the development possibilities of the important brackish spring Almyros with a mean discharge of 7 m3/s on Crete island in Greece.
