Article
The Gort Lowlands is an extensively karstified lowland limestone catchment located in Co. Galway, on the western coast of Ireland. The hydrogeomorphological history of the Gort Lowlands is complex; recurrent karstification and glaciation of the Carboniferous limestone formations has created an extensive conduit and cave system that dominates ground...

Almost a half of the Republic of Ireland is underlain by Carboniferous limestone, most of which is sufficiently pure to be karstified. Upland outcrops of limestone are largely confined to plateaux in the west and NW such as the Burren but the great majority of the limestone underlies the undulating lowland of central Ireland, which only locally exc...
Article
Almost seven hundred caves are known to exist in the Republic of Ireland and they are a significant component of the physical and cultural environment. However, the value of caves is largely unappreciated except by those with specialist interests. A database has been compiled, available in a searchable on‐line format, of all caves in the Republic....

In order to achieve some consistency in the establishment of groundwater intrinsic vulnerability maps in Europe, a new approach is proposed by Working Group 1 of the European COST Action 620 on "Vulnerability mapping for the protection of carbonate (karst) aquifers". A general procedure is offered which provides consistency while allowing the requi...
Article
In lowland karsts, both surface and groundwater systems are often present. This is the case over large areas of limestone in the west of Ireland where gaining and losing streams and seasonal lakes (turloughs) are common and where much of the surface river system consists of artificial channels. A case study from County Clare illustrates the problem...
Article
The Burren plateau of County Clare is a classic example of a plateau karst characterised by patchy, thin soils, a lack of defined surface drainage, and in the instance of the Burren, a rich floristic, archaeological and landscape heritage. Since accession to the European Union and, in particular, as a result of Common Agricultural Policy initiativ...
Article
Lisdoonvarna is a small town with a resident population of ca. 700, which is seasonally increased several-fold by tourists. It is located in the northwest of County Clare, western Ireland about 10 km from the Atlantic seaboard and adjacent to the karstic Burren plateau. Lisdoonvarna has two claims to fame: it is the only currently operative spa in...
Article
Between 1981–1991, 4% of the Burren area (1371ha) was reclaimed under the Programme for Western Development. Most of the reclamation was intensive and the land is being used to produce silage. Although more efficient and intensive agriculture is now possible, there has been a corresponding loss of environmental variety as scrub, semi-natural grassl...
Article
The paper describes the hydrology, both relict and modern, of the Geevagh and Bricklieve upland karsts in Co. Sligo. The Geevagh karst is characterised by point recharge via sinking streams running off juxtaposed non-carbonate rocks. The flow mechanism in the karst. as determined by water tracing and hydrochemical analysis, is both conduit and fiss...
Article
The Burren plateau of northwest Co. Clare is extensively karstified, surface water being confined to short reaches of ephemeral streams, seasonal turloughs and drainage from adjacent non-carbonate rocks. Annual precipitation is c. 1500mm of which c.980mm is not evapotranspired. Recharge is rapid, either via concentrated inputs from sinking streams...

The impact of land drainage on groundwater resources is particularly acute in karst areas because of the unique characteristics of karstic aquifers. Arterial drainage of karst lowlands in Ireland, involving the construction of artificial river channels, has resulted in losses of recharge,lowering of water tables, drying up of seasonal lakes (turlou...
Article
The W part of the central lowland of Ireland in E County Galway, E County Mayo and County Roscommon, is an area of subdued topography rarely rising over 60m. The landforms are in part of glacial origin and in part karstic, and include many turloughs (seasonal lakes). Techniques from karst hydrology (eg dye tracing) and from conventional geohydrolog...
Article
The Burren is a plateau karst on the west coast of Ireland. It is characterized by thin soils, patchy vegetation and large areas of bare rock, supposedly a legacy of glacial erosion. Archeological and palynological evidence suggest that the area was well populated and forested in prehistoric times, though now it is a marginal area agriculturally. I...
