Project Title

Cliffs of Moher Geohazard Assessment | Arup

Date

2019/2020

Location

Cliffs of Moher, Co. Clare

Client

Cliffs of Moher Visitor Centre & Clare County Council

Services (Technical Disciplines)

Arup undertook a geohazard identification and risk assessment of the 200m high cliffs at the Cliffs of Moher, at the Burren and Cliffs of Moher UNESCO Global Geopark.

Following on from a series of visual inspections and field mapping, a baseline 3D digital model comprised of over 37 million data points was developed using a combination of remote data capture from drone, geophysical and topographical surveys and subsequently interpreted to undertake a rockmass assessment along the cliff top and face. You can view the drone footage here.

Project Outcomes/Objectives

This digital baseline model can be updated through ongoing monitoring along with feeding into any design considerations at the Cliffs.

Further applications of the model and this important dataset, include the measurement and monitoring of the potential impacts of climate change from increased storm events at the Cliffs along with providing a visual aid for tourists to the Visitor Centre.
