A borehole is any hole drilled or dug into the ground. The hole is usually deep, narrow and round. 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...

ScienceGroundwater is the water that soaks into the ground from rain and can be stored beneath the ground. Groundwater floods occur when the water stored beneath the ground rises above the land surface. The Groundwater Flooding Medium Probability map shows the expected flood extent...

This Hydrostratigraphic Rock Unit Groups map is a reclassification of the 1:100,000 bedrock geology map, created by grouping bedrock formations and members into 27 Rock Unit Group categories based on their hydrogeological properties and other factors.

Karst is a landscape with distinctive landforms that develop on rock types that are readily dissolved by water. In Ireland, karstification mostly occurs in limestone regions. This karst dataset contains mapped karst landforms in Ireland including: boreholes, caves, dry...

The groundwater vulnerability concept is based largely on the question “can water and contaminants move in the subsurface materials (soil and subsoil) and/get down to groundwater easily?” Groundwater is most at risk where the subsoils are absent or thin and in areas of karstic...

This database contains records of boreholes, dug wells, springs, and site investigations. Data are derived from GSI drilling, fieldwork and surveys, Local Authorities and other state bodies, Private Well Grants, Drillers, Consultants, Group Water Schemes and Academia. It is...

The Groundwater Subsoil Permeability map classifies how easy water can infiltrate subsoils downwards at any point in the land surface. Permeability across the country is classified as either ‘High’, ‘Moderate’ or ‘Low’. This map is used to determine groundwater vulnerability...

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....

The term Physiography can be described as a blending of “physical" and "geography". Physiographic Units show Ireland’s physical landscape divided into categories such as ‘Bedrock plain’ and ‘Flat to undulating sediments’. Areas are grouped based on bedrock geology (solid rock...

Landslide locations and extents help us locate where landslides have occurred. Ireland's location, terrain and climate result in landslides occurring mainly in areas with steep slopes where rock meets the surface and peat covers the terrain. Landslides have the potential to...

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....
