Assessment of the effectiveness of a rockfall ditch through 3-D probabilistic rockfall simulations and automated image processing
Rockfall ditches or catchment areas aim to collect falling blocks at the toe of a source zone by dissipating the energy of blocks in an excavated trench. The effectiveness of a rockfall ditch is simply expressed by its blo...
Assessment of damage zone thickness and wall convergence for tunnels excavated in strain-softening rock masses
Satici, Ozguer; Topal, Tamer (2021-02-01)
There are two fundamental issues in all underground excavations, which are safety and economy. To ensure safety and expedite excavations, level of tunnel wall convergences and damage zone thickness should be predicted befo...

The Anatolia (Eurasia), Arabia, and Africa tectonic plates intersect in southeast Turkey, near the Gulf of Iskenderun, forming a tectonically active and unstable triple junction (the A(3) triple junction). The plate bounda...
Implications of giant ooids for the carbonate chemistry of Early Triassic seawater
Li, Xiaowei; Trower, Elizabeth J.; Lehrmann, Daniel J.; Minzoni, Marcello; Kelley, Brian M.; Schaal, Ellen K.; Altıner, Demir; Yu, Meiyi; Payne, Jonathan L. (2021-02-01)
Lower Triassic limestones contain giant ooids (>2 mm) along with other precipitated carbonate textures more typical of Precambrian strata. These features appear to have resulted from changes in seawater chemistry associate...
