DESIGNING AND EXECUTING ENVIRONMENTAL-FRIENDLY REINFORCEMENT SYSTEM TO STABILIZE A PROGRESSIVELY FAILED HISTORICAL WATERFALL

This paper presents the techniques applied to stabilize a progressively toppling steep rock slope (waterfall) situated about 20m downstream from an intake dam. First, using a distinct element analytical model of the slope a suitable rock reinforcement system is designed and analyzed so as to prevent the instabilities of the slope. In addition, a rigorous process of construction works is followed while installing the rock reinforcement elements in order to protect and enhance the geoenvironment of the site. Completion of the construction works has convincingly resulted the original aesthetic of the waterfall assuring its stability during flooding, the commonest natural event of the area, with reasonable cost.
