This data article presents a rich original experimental video sources and wide collections of laboratory on water levels, sediment depths wave front celerity values arose from different multiphase dam-break scenarios. The required shock waves in highly silted-up reservoirs with various initial up- down-stream hydraulic conditions is obtained directly high-quality videos. multi-layer were record...

Near the critical point, isothermal interfacial zones are investigated starting from a non-local density of energy. From the equations of motion of thermocapillary fluids [1], we point out a new kind of adiabatic waves propagating along the interfacial layers. The waves are associated with the second derivatives of densities and propagate with a celerity depending on the proximity of the critic...

Abstract The water saving lock layout plays a key role in addressing the navigation hydraulic problems with high dams. However, study of propagation and development nonlinear long waves induced by ship-lock operation basin has received less attention so far. Specially, mechanisms governing formation secondary impact these on impoundments are still not fully understood. In present entire evoluti...

Abstract In part 1 (Gouin, [13]), we proposed a model of dynamics of wetting for slow movements near a contact line formed at the interface of two immiscible fluids and a solid when viscous dissipation remains bounded. The contact line is not a material line and a Young-Dupré equation for the apparent dynamic contact angle taking into account the line celerity was proposed. In this paper we con...

In 1805, Young was the first who introduced an expression for contact angle in static, but today, the motion of the contact-line formed at the intersection of two immiscible fluids and a solid is still subject to dispute. By means of the new physical concept of line viscosity, the equations of motions and boundary conditions for fluids in contact on a solid surface together with interface and c...

[1] Tidal wave propagation can be described analytically by a set of four implicit equations, i.e., the phase lag equation, the scaling equation, the damping equation, and the celerity equation. It is demonstrated that this system of equations has an asymptotic solution for an infinite channel, reflecting the balance between friction and channel convergence. Subsequently, explicit expressions f...

Negative surges can be caused by a sudden change in flow resulting from a decrease in water depth. In the present study, some physical experiments were conducted in a rectangular channel to characterize the unsteady free-surface profile and longitudinal velocity beneath a negative surge propagating upstream. The physical observations showed that, during the first initial instants, the celerity ...

In an estuary, a tidal bore may be generated at the leading edge of the flood tidal wave during the early flood tide under spring tide conditions into a narrow funnelled channel. For Froude numbers greater than 1.4–1.6, the leading edge of the bore is characterised by a breaking roller. The roller is characterised by a sudden increase in water depth, a highly turbulent flow with large-scale vor...

Over the last 200 years, streams throughout Australia have been channelised to increase their hydraulic conveyance, and so reduce flood peaks and durations. One of the main channelisation activities has been to remove large woody debris (LWD) and bank vegetation. Ironically, the major stream rehabilitation activity in Australia, and in many countries, over the last two decades, has been to reve...
