We concluded that the landslide dam consisting of loose deposits of the rockfall might be vulnerable for overflow, and the longevity of the dam will be short.
Seasonal time series like the fly activity data measured by the DAM consist of trend and periodic components.
The dam body consists of two layers: the top layer with mainly rock fragments (~40%) as well as large boulders and blocks (~50%); and the bottom layer with almost intact rock mass (Fig. 10d and e).
The first one is that the dam foundation consists of rock blocks, with joints and so-called 'rock bridges' and the gently dipping joints play a critical role in the foundation stability against sliding.
The bedrock and abutments of the dam site consist of Asemari and Gachsaran Formations.
Construction of the dam began on October 20 , 1961 with the placing of the dam embankment, which at least partially consists of acidic sediment dredged from Spring Creek.
These include the archive for New Zealand (Korup, 2004), which consists of 232 dams, the Swiss database (Bonnard et al., 2011), with 31 cases and the Chinese one, which has even 1239 cases (Peng and Zhang, 2012) and a database of a single regional triggering event with 828 cases during the earthquake of May 12 , 2008 in Wenchuan (Fan et al., 2012a,b,c).
This system of engineering measures is based on the main river's transport capacity and consists of five check dams with various opening sizes, a drainage channel with sidewalls constructed of prefabricated reinforced concrete boxes, and a debris flow basin at the base of the main gully.
Dams were grouped into six; each group consists of six animals.
