Unsteady two-dimensional distribution of suspended sediment transport in open channels
The current work presents a two-dimensional (2D) unsteady suspended sediment transport model for an open channel turbulent flow. Unlike most of the...

Different physics but similar dependence of runout distance with discharge rate: the duality of pyroclastic density currents
We address emplacement mechanisms of pyroclastic density currents (PDCs) through relationships between their runout distance and mass discharge rate...

Semi-analytical study on environmental dispersion of settling particles in a width-independent wetland flow
Predicting the evolution of environmental dispersion of settling particles in wetland flows has a wide range of applications in ecological...

Experimental settling, floatation and compaction of plagioclase in basaltic melt and a revision of melt density
Centrifuge-assisted piston cylinder experiments were conducted on plagioclase in basaltic melt at 1140–1250 °C, 0.42–0.84 GPa and mostly 1000 g. One...

Unsteady numerical simulation of suspended load in relation to grain-size distribution
A theoretical model is presented here for the transient grain-size distribution of non-uniform sediments in suspension over erodible sediment beds...

Validation and Application of a Three-Dimensional Model for Simulating Proppant Transport and Fracture Conductivity
Hydraulically fractured well productivity greatly depends on fracture conductivity, which itself is dictated by proppant transport and placement. To...

The strongly peraluminous, garnet-bearing norite–quartz jotunite–charnockite suite: products of crystal accumulation in the felsic magma reservoir
Fractionation of felsic magma has been critical for the formation of high-silica rhyolites, chemical differentiation of the continental crust, and...

Analytical expression for predicting the reduced settling velocity of small particles in turbulence
The influence of turbulence on the settling velocity of small particles remains an inconclusive research subject. Both enhanced and retarded particle...

Cohesional behaviours in pyroclastic material and the implications for deposit architecture
Pyroclastic density currents (PDCs) are hazardous, multiphase currents of heterogeneous volcanic material and gas. Moisture (as liquid or gas) can...

The hyperturbid state of the water column in estuaries and rivers: the importance of hindered settling
Over the last few decades, some estuaries have undergone a transition to a hyperturbid state, characterised by suspended sediment concentrations of...
