Free surface problems occur in many aspects of science and of everyday life such as the
waves on a beach, bubbles rising in a glass of champagne, melting ice, pouring flows from a …

Hydraulic engineering of dams and their appurtenant structures counts among the essential
tasks to successfully design safe water-retaining reservoirs for hydroelectric power …

Free-surface flows past a submerged triangular obstacle at the bottom of a channel are
considered. The flow is assumed to be steady, two-dimensional and irrotational; the fluid is …

Two-dimensional free-surface flow past disturbances in an open channel is a classical
problem in hydrodynamics—a problem that has received considerable attention over the last …

Nonlinear waves in a forced channel flow are considered. The forcing is due to a bottom
obstruction. The study is restricted to steady flows. A weakly nonlinear analysis shows that …

This paper focuses on the temporal and spatial evolutions of critical flow under unsteady
rapidly varied flow conditions, which is defined based on different viewpoints under steady …

Free-surface flows past submerged obstacles in a channel are considered. The fluid is
assumed to be inviscid and incompressible and the flow to be irrotational. In previous work …

Free-surface flows past submerged obstacles in a channel are considered. The fluid is
assumed to be inviscid and incompressible and the flow to be irrotational. The first-order …

The inverse problem of steady two-dimensional open channel free-surface flow is
considered, with the focus on determining two types of disturbances: a surface pressure …

Long nonlinear waves in the two-layer flow of an inviscid, incompressible fluid are
considered. Both the free surface and the interface of the two fluids are unknown free …
