The application of landslide potential hazard zonation mapping in the Ebbw Valley , Gwent, Wales , United Kingdom

The application of landslide potential hazard zonation mapping in the study area is based on the successful application of this method used in the Rhondda Valley which is also facing landsliding problems. This method involves dividing of the study area into square grids 100 ´ 100 m2 representing bas...
