Marine diversity is currently one of the most studied topics in ecology especially under the frame of global and regional environmental changes. In the marine realm biodiversity declines from the tropics to the Arctic (Thorson 1957, Brattegard & Holthe 1997, Roy et al. 1996, 1998, Gray 2001). Habitat and environmental heterogeneity generally favour biodiversity; additionally, intermediate physi...

In this paper, scouring shear failure theory is optimized based on the gangue slope near thermal power field in Baiguo Town, Panzhou City, Guizhou Province. Based particle flow PFC (particle code) 3D fluid–solid coupling method, mechanism of ditch no. 5 comprehensively analyzed from perspectives mode, displacement, motion track, and stress–strain. We consider respect (c, φ); dominated by two ty...

Accurately predicting scour is important for its prevention around the foundations of offshore wind turbines. Many studies on local piles have been conducted. Chen et al. (2022) conducted analysis using largescale experiments and examined maximum depth. However, relationship between depth time has not yet investigated. Furthermore, only a few comprehensively scale effects similarity laws. In th...

Abstract Bridge foundation scour is one of the major problems for bridges in Nepal. Kathmandu Valley, which main economic hub and capital Nepal lies a seismically active zone. In this study, bridge spanning over Bagmati River Valley studied as reference to assess seismic response typical affected by scouring. Modal analysis revealed becomes more flexible when depth 2 m considered. A series push...
