Abstract: The motion of conservative 2D thermals on beds with slope angles θ ranging from 5 to 90° is investigated theoretically and experimentally. Using a large number of experimental data, important flow characteristics, including ...

Abstract: Experiments are conducted in a horizontal laboratory channel with slightly diverging walls to simulate buoyancy driven plunging flow. A temperature difference between inflow and downstream ambient provides the density ...

Abstract: The flow considered herein is a two‐dimensional negatively buoyant flow from a shallow channel over a sloping bottom (mild or steep) into a well‐mixed reservoir. For the analysis, a set of integral equations, in particular ...

Abstract: The behavior of two-dimensional (2D) flood flows and the hydrodynamic force acting on structures are investigated numerically and experimentally. Numerical simulations are performed using a model based on the finite-volume ...

Abstract: Meander bends of high amplitude in alluvial rivers often display a high degree of coherency. The only analytical equation heretofore available to describe such bends is the sine‐generated curve, which has no rigorous ...

Abstract: Layer‐averaged equations describing the characteristics of a two‐dimensional unsteady inclined starting plume, which consists of two parts, i.e. a front part and a body part, are derived. A numerical model is formulated ...

Abstract: Two numerical models for 2D flood flows are presented. One model is first-order accurate and another is second-order accurate. Roe's numerical flux is used to develop the first-order accurate model, while second-order ...
