Flow at an Ogee Crest Axis for a Wide Range of Head Ratios: Theoretical Model

The discharge coefficient of an ogee crest is a function of the ratio of the effective head to the design head. The purpose of the present study is to derive a theoretical model of this relation,

On the Fluid Mechanics of Self-Aeration in Open Channel Flows

This dissertation is organized in five parts and a historic analysis of air-water flow research in open channel flows is presented, jointly with a detailed discussion on research trends.

Vertically Averaged and Moment Equations for Dam-Break Wave Modeling: Shallow Water Hypotheses

The dam-break wave modeling technology relies upon the so-called shallow water equations (SWE), i.e., mass and momentum vertically averaged equations by implementing the shallow water hypotheses,

Depth-averaged modelling of granular dike overtopping

Failure of river dikes due to overtopping is a dangerous phenomenon to be avoided, and a complex unsteady sediment transport problem that is under intense scientific consideration. Mathematical

Near-critical turbulent free-surface flow over a wavy bottom

Steady plane turbulent free-surface flow over a slightly wavy bottom is considered for very large Reynolds numbers, very small bottom slopes, and Froude numbers close to the critical value 1. As in

Shallow fluid flow over an obstacle: higher-order non-hydrostatic modeling and breaking waves

The simulation of shallow flows over obstacles is an important problem in environmental fluid dynamics, including exchange flows over seabed sills, atmospheric flows past steep mountains and water

Oblique stationary solitary waves in turbulent free-surface flow

It is shown that an oblique solitary wave may be caused by an oblique strip of enlarged bottom roughness. The analysis is valid for very large Reynolds numbers and very small slopes. Considered are
