Numerous landslides and landslide restorations – an example
Abstract
Numerous landslides appeared in a smaller area of north-western Croatia during a short span of time; in a large number of casesthese landslides infringed upon local roads, public objects and other landscape. As is well known, the phenomenon of multiplelandslides is connected to specific hydrometeorological features of the period, but also with geotechnical sensibilities of the terrain,which has a bearing on destabilizing factors. As this high number of landslides was previously unheard of, the action of preparingdocumentation for their restorations was also quick and arduous. A high level of systematization and a plan involving the approachto solving the problem as a whole and in phases is necessary for any mass-restoration/reconstruction approach. The paper deals withthe characteristics of landslides in the examined area, with cause(s) of appearance of these numerous landslides, with investigationsand restorations of landslides, and with additional notes to keep in mind when examining the problem and constructing the solution.Geometry, geological content, frequent geotechnical characteristics, etc. will be described as landslide characteristics. Thesehydrometeorological causes will be examined more closely through time. Familiarizing with multi-landslide locations, i.e. makingthe correct diagnosis is then followed by mass restoration. In order for restoration to be successful, one must set a good conceptof effectiveness - which is arrived at through correct analysis of area characteristics. The paper also describes the chosen waysof restoration/reconstruction, emphasizing that these were solutions minimizing possibilities of errors in mass restoration.
