Incipient Motion of Sediment Particles over Loose
New experimentals work were conducted to study the effects of sediment deposits’ thickness on the incipient motion of particles in a rigid rectangular channel. The results show that the deposits’ thickness significantly affects the channel’s ability to erode the sediment deposits. New equations were derived taking into account the effects of deposits’ thickness.

15 صفحه اولNumerical Simulation of Free Seepage Flow on Non-matching Grids
A new domain decomposition technique on non-matching grids for free boundary problems is considered. An iterative DD scheme is used to reduce the original free boundary problem to a sequence of problems on two sub-domains, one of which includes the free boundary and is described by a variational inequality and the other includes the remainder of the problem and is described by a second order pa...
متن کاملOn the Number of Incipient Spanning Clusters
In critical percolation models, in a large cube there will typically be more than one cluster of comparable diameter. In 2D, the probability of k >> 1 spanning clusters is of the order e k 2 . In dimensions d > 6, when η = 0 the spanning clusters proliferate: for L → ∞ the spanning probability tends to one, and there typically are ≈ L spanning clusters of size comparable to |Cmax| ≈ L. The rigo...
