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...

Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock map shows what the land surface of the North East, Midlands, Cork and Dublin would be made up of if these materials were...

Karst is a type of landscape where the bedrock has dissolved and created features such as caves, enclosed depressions (sinkholes), disappearing streams, springs and turloughs (seasonal lakes). Limestone is the most common type of soluble rock. As rain falls it picks up carbon...

Public Water Supplies (PWSs) are managed by Irish Water, Ireland's national water utility, since 2013. Before this, public water supplies were managed by Local Authorities. More than 70% of public supplies take groundwater from boreholes, springs and infiltration galleries....

This dataset is the GSI’s legacy borehole database, compiled over many years from many sources. This dataset is available while we make significant improvements to our borehole holdings.

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....

In terms of time scale in geology, Quaternary is the present-day time and it began 2.6 million years ago. A lot of this time period relates to the Ice Age. Quaternary Geomorphology shows features left on the earth’s surface during this time. Glaciers and ice sheets, which are...

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...
