Water-surface oscillations in channels with axi-symetric cavities

Transverse or longitudinal movements of a water body are observed for flows along cavities, river embayments, groyne fields or harbours. They are significant for certain flow conditions and geometrical properties. To study the effect of large-scale roughne ...

LSPIV implementation for environmental flow in various laboratory and field cases

Anton Schleiss, Sameh Ahmad Kantoush

Large-Scale Particle Image Velocimetry (LSPIV) is an extension of a quantitative imaging technique to measure water surface velocities using simple and inexpensive equipment. This paper describes the implementation of imaged-based LSPIV in eight different ...

Effects of wave characteristics and beach groundwater table on the nearshore morphology and aquifer dynamics

David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar

A Navier-Stokes hydrodynamic model with a VOF method and a turbulence closure solver was used to simulate wave motion on permeable beaches. Coastal aquifer dynamics, the interactions between the groundwater and the seawater, and the effects of wave motions ...

Cross-shore sediment transport estimation using fuzzy inference system in the swash zone

Roham Bakhtyar

The interactions between fluid and sediment in the swash zone dominate the erosion or accretion of the beach, and they act as boundary conditions for nearshore hydrodynamic and morphodynamic models. Thus, the evaluation of sediment transport is of particul ...

Modern comprehensive approach to monitor the morphodynamic evolution of a restored river corridor

Paolo Perona

River restoration has become a common measure to repair anthropogenically-induced alteration of fluvial ecosystems. The inherent complexity of ecohydrologic systems leads to limitations in understanding the response of such systems to restoration over time ...

Air-water two-phase flow modeling of turbulent surf and swash zone wave motions

David Andrew Barry, Roham Bakhtyar, Amir Mehdi Razmi

Wave breaking and wave runup/rundown have a major influence on nearshore hydrodynamics, morphodynamics and beach evolution. In the case of wave breaking, there is significant mixing of air and water at the wave crest, along with relatively high kinetic ene ...

Flow exchange between a channel and a rectangular embayment equipped with a diverting structure

Anton Schleiss, Jean-Marc Ribi

In the framework of a research project focusing on mitigation measures for hydropeaking, a lateral embayment in riverbank is studied as a fish shelter. With the goal to find attractive configurations of shelter, systematic experiments with wild juvenile br ...

Process-based model for nearshore hydrodynamics, sediment transport and morphological evolution in the surf and swash zones

David Andrew Barry, Roham Bakhtyar

Nearshore hydrodynamics and sediment transport in the nearshore zone were modeled numerically taking into account turbulent unsteady flow. The flow field was computed using the Reynolds Av-eraged Navier-Stokes equations with a k-ε turbulence closure model, ...

Modeling sediment transport in the swash zone: A review

David Andrew Barry, Roham Bakhtyar

A critical review of conceptual and mathematical models developed in recent decades on sediment transport in the swash zone is presented. Numerous studies of the hydrodynamics and sediment transport in the swash zone in recent years have pointed out the im ...

Numerical simulation of surf-swash zone motions and turbulent flow

David Andrew Barry, Roham Bakhtyar

A two-dimensional numerical model was presented for the simulation of wave breaking, runup and turbulence in the surf and swash zones. The main components of the model are the Reynolds-Averaged Navier-Stokes equations describing the average motion of a tur ...
