| Zusammenfassung |
| Landslide-induced wave in lakes or offshore is a natural hazard of
significant concern throughout the world. In Turkey, several dam reservoir
areas suffer from this problem, motivating for the exploration of this phenomenon.
In this study, the potential for landslide-induced wave generation and the
possible adverse effects of such an event were investigated for the Kurtun
Dam reservoir area. This area is prone to translational debris-type
landslides, and such slides represent a threat with respect to wave
generation. To investigate this problem, a potential landslide was initially
inspected with respect to key geometrical and index parameters, such as
the internal friction angle and unit weight of the landslide material. After
obtaining these data, the potential of sub-aerial landslide-induced wave
characteristics such as wave height, wave run-up on the opposite slope and
wave velocity were calculated using existing empirical relationships. Based
on the obtained wave properties, a potential damage assessment was performed
for vulnerable areas in recognition of the fact that the Kurtun Dam and
Kurtun district are threatened by potential wave occurrence. According to
the findings obtained from the potential damage assessment, it was
determined that the Kurtun district and the Kurtun portion of the
Kurtun-Gumushane highway are located within the run-up impact area. However,
the Kurtun Dam was determined to be relatively safe due to the distance
between the landslide area and the dam. |
