Water tracing involves tagging water to see where it goes. The time the tracers take to get from one point to the other is also usually recorded. It is most commonly used in karst environments to ascertain groundwater flow rates, directions and catchment definitions (Zone of...

Bedrock outcrop polygons have been derived from digitising outcrop locations from scanned 19th Century GSI field maps. The data was derived from mapping at a scale of 1:10,560 (6 inches to one mile). Individual map sheets were geo-referenced to an index polygon and checked...

Before building new structures engineering companies carry out a site investigation to find out the quality of the ground (strength and depth of soil and to see if rock and or groundwater is present). These investigations involve digging holes such as trial pits and boreholes....
-
A borehole is any hole drilled or dug into the ground. The material (soil and or rock) from the hole is collected and tested in a laboratory to find out the structure and type of the soil and or rock beneath the ground. A borehole record or log is a written description of the...

ScienceA landslide is the movement of material down a slope. This includes rock, earth, mud and peat. Landslides in Ireland mainly occur on steep mountain slopes. A landslide susceptibility map shows areas where a landslide could occur, how likely it will occur and what causes them....

The 1:500k bedrock maps provide a simplified, smaller scale view of the bedrock geology of Ireland. The map was created in 2013 using the detailed 1:100k geology linework and polygons, which was adjusted and scaled to provide the best representation of the geology at this...
