Non-Hydrostatic Free Surface Flows

This book provides essential information on the higher mathematical level of approximation over the gradually varied flow theory, also referred to as the Boussinesq-type theory. In this context, it presents higher order flow equations, together with their

We would like to dedicate this work to: Oscar’s wife Elena, and his sons Jaime (7 years), Matias (6 years) and Pablo (1 year). Their lovely support, and steady smiles to Oscar every morning when all the family wakes up, constantly gave him the fresh energy to successfully convey this project. Willi’s wife Susanna and their three daughters Olivia, Mirjam, and Caren, who have contributed to this work by their support and constant encouragement. Oscar Castro-Orgaz and Willi H. Hager

Preface

The computation of unsteady free surface flows has an important place in disciplines such as civil, environmental, and coastal engineering, given the need to solve real-life problems associated with this fascinating type of hydraulic motion. During the past decades, their three-dimensional (3D) computation using RANS and LES models gained impulse, permitting an accurate numerical solution of complex hydraulic flows. These numerical solutions are usually coupled in a hybri
