Three-dimensional numerical simulations of a flow past non-submerged diversion dike are performed for various blockage ratios (1/6 ≤ β 1/3) and Froude numbers (0.152 Fr 0.253). The instantaneous time-averaged characteristics, the evolution process mixing layers, bed shear stress analyzed. ratio plays an important role in momentum redistribution turbulent kinetic energy dike. As increases, veloc...

A depth-averaged 2-D model has been developed for simulating coastal barrier breaching processes. The model solves the generalized shallow water equations and the non-equilibrium sediment transport and bed change equations in a coupled fashion using an explicit finite volume method on a rectangular grid. It considers interactions among transient flow, strong sediment transport, and rapid bed ch...

Titanium-rich clinohumite and layered structure minerals are observed in kimberlite and as inclusions in pyropic garnets from the Moses Rock dike, a kimberlite-bearing breccia dike in San Juan County, Utah. Associated clinopyroxenes observed as inclusions within similar pyropes and also in kimberlite are estimated to have equilibrated at depths ranging from about 50 to 150 km at modest temperat...

Minimization differences on Cellular Automata approach to predict new inundated area of hot mudflow on LUSI mud eruption disaster which occurred in Sidoarjo area is proposed. There are three characteristics of hot mudflow that is unique such as sur face material changes rapidly, surface temperature changes quickly and dike is constructed to avoid spill over. There are penetrations of hot mudflo...

Although the source layer for marine magnetic anomalies has been assumed to be the extrusive basalts of uppermost ocean crust, recent studies indicate that lower crustal rocks may also contribute. Because the temperature at which magnetization of crustal rocks achieves long-term stability is crucial to any source layer contribution, we undertook hightemperature VRM (viscous remanent magnetizati...

We find a system of two polynomial equations in two unknowns, whose solution allows us to give an explicit expression of the conformal representation of a simply connected three-sheeted compact Riemann surface onto the extended complex plane. This function appears in the description of the ratio asymptotic of multiple orthogonal polynomials with respect to so-called Nikishin systems of two meas...
