The evaluation of experimental protection examining of eroded waterfalls on tuff beds - example: Town Jajce

The applicable methods for technical stabilization of waterfall are conditioned by natural, architectural, historical values of the landscape. That is a reason why concrete or reinforced concrete structures should be avoided and why binders for natural tuff detritus that do not change the shape or color of naturally hardened tuff are preferred. In this paper the possibilities of technical interventions in waterfall area that are formed in heterogeneous tuff sediments are described. The rivers Pliva waterfall is a unique natural phenomenon, placed in the middle of an old town Jajce, and therefore is an ideal and unique test field. This landscape uniqueness, conditions the innovative approach to the waterfall erosion problem. As a possibility of waterfall erosion protection injection suspensions were examined. Laboratory experiments have shown good results, on a large number of samples of tuff beds, when injected with micro-cement. Also the usability of other injection suspensions was examined within the research region. The injection suspensions were adjusted according to the tuff lithological composition. Comparison of the control samples have shown acceptable results of the applied methods, both in the laboratory and on the site.
