Landslides Workshop 2009


Geological Survey of Ireland

Landslides Workshop 21 April 2009

The GSI Landslides Workshop was held in GSI on Tuesday 21 April last. There were 86 delegates for the day and was thus considered a great success, and indicated the degree of concern held by people from around the country about landslide geohazard. The objects of the meeting were to introduce a wide range of stakeholders to the GSI Landslides Susceptibility Mapping Project and to consider landslide geohazard issues in Ireland today.

The Workshop contained a series of presentations covering a wide range of topics including susceptibility mapping methods and geotechnologies, geotechnical engineering of landslide materials, landslides and the planning process, remote sensing and GIS, as well as a number of case studies.

The multi-disciplinary nature of these talks was reflected in the delegates who attended. They included geologists, geomorphologists, geophysicists, engineers, planners, and a range of environmental scientists. This is an indication that landslide study very much demands a multi-disciplinary approach as landslides can have considerable societal impacts. The delegates came from central and local government, state and semi-state agencies, universities, and private consultancy companies.

The impact of future climate change was a major theme running through the day with the likelihood of more landslides in the future with higher and more intense rainfall in certain parts of western and northwest Ireland as well as increased coastal erosion due to sea level rise.

The great interest shown in this meeting would suggest that another one could be held next year to give an update on all the research that is going on.
