The entrainment assumption, relating the inflow velocity to the local mean velocity of a
turbulent flow, has been used successfully to describe natural phenomena over a wide …

The literature on the structure and behaviour of gravity currents is reviewed, with emphasis
on some recent studies, and with particular attention to turbidity currents, though reference is …

The complexity of flow and wide variety of depositional processes operating in subaqueous
density flows, combined with post‐depositional consolidation and soft‐sediment …

Ignimbrites are vast, landscape-modifying deposits composed mainly of pumice fragments
and ash. They derive from the most. hazardous types of explosive volcanic eruptions and …

Hyperpycnal flows originate when sediment-laden fluvial discharges enter standing, lower-
density water. Because of their excess density, the flows plunge near the river mouth and …

This paper describes experiments and numerical simulations of a gravity current flowing
down a ramp in a tank stratified in two layers. We study the dynamics of the configuration for …

In this study, simple analysis, numerical simulations and verified experiments are conducted
to investigate the smoke backlayering length in inclined tunnel fires under natural …

Two-dimensional buoyant clouds moving along inclined boundaries under a gravitational
force are investigated theoretically and experimentally. It is found that the 'thermal …

Prominent among the pyroclastic deposits of Santorini are several thick, widespread lithic
breccia deposits, which are found in intimate association with ignimbrite. At least three of …

The creation of river dams and the storage of water have been a strategy for survival for
many centuries. Reservoirs have diverse functions, providing irrigation, water supply …
