Ogee spillway is the most important structure used to get rid of excess water during flood. Scouring phenomenon occurring in downstream region due high energy dissapation an envitable. This study aims reduce amount scour occurred at stilling basin ogee by using three dissipation blocks namely as baffle, triangle and stepped blocks. A new distribution was proposed for each type dissipated block,...

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...

In single-bend channels or meandering channels, groynes are widely used as a river-training structure. Geometric factor is an important principle of groyne design. this paper, the numerical method based on Renormalization Group (RNG) k-ε turbulence model to study effects with different lengths and orientations mean flow pattern characteristics in mildly channel. The analysis shows that compared...

I . Piglets were left to suckle their dam for about z days after birth to obtain colostrum and were then divided into four groups. One group was left with the sow, the second was given a standard liquid diet based on cow’s milk, the third the standard diet with lactic acid added to give a pH of 4.8, and the fourth the standard diet with the casein content increased by 50 yo. Stomach samples wer...

Physical models have suggested a large reduction in bearing capacity of simple foundations due to overtopping tsunami scour. We use the results these tests create scoured foundation geometries for breakwater-type structures and investigate change system’s scour through two-dimensional (2D) numerical analysis using an advanced constitutive model. The particular aspects construction such general ...
