In hilly and mountainous locations, it is difficult to control geohazards. Rockfalls, landslides, mudslides or avalanches are sporadic and unpredictable phenomena. It is frequently not possible to guarantee the security of people and structures using scientific methods. Reconnaissance surveying of the territory is required to identify all geohazards, followed by continuous monitoring, careful calculation of the required parameters and the necessary engineering calculations, with the subsequent professional installation of protective structures. An integrated approach to resolving the task will be most effective and reduce loss of life and material damage to a minimum.
Solutions to prevent geohazards can be both permanent and large-scale (retaining walls, mudslide diversion structures, galleries) which involve a long production time, large capital expenditure and changes to the relief of the slope, or on the other hand less expensive and time-consuming (mudslide barriers, anchoring, dowels), which are often a more effective means of protection.
