The Hydrology and Caves of the Geevagh and Bricklieve Karsts, Co. Sligo

Richard Thorn, David Drew, Catherine Coxon


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 fissure and there is extensive cave development. The Bricklieve karst lacks an impermeable cover to concentrate flow and recharge is largely diffuse. Flow in this karst appears to be predominantly through a network of solutionally widened fissures and cave development is limited.
