On the angles of dry granular heaps

Web29 de abr. de 2024 · The slope of the top heap is close to 0° with respect to the horizontal direction, and the slope around the bottom is close to constant, depending on the coefficient of friction between blocks. These properties are challenging to apply to granular heaps. Web14 de abr. de 2024 · The passivation on rock granules in the coated cover increased the water entry value (WEV) of the CGS layer to −0.56 kPa. This led to a 15 mm water storage increment in the overlain FGS layer as compared to that in the uncoated cover, and induced lateral drainage (5% of the precipitation) in the FGS layer, which was not overserved in …
