Monitoring of Steel Lined Pressure Shafts Considering Water-Hammer Wave Signals and Fluid-Structure Interaction
In the past, the safety margin for dynamic water pressure loads in steel-lined pressure tunnels and shafts was considered as acceptable by using conventional design safety factors. Due to high peak energy demands, existing plants are operating nowadays und ...
EPFL2011Impacts of 3D wave and tidal forcing on nearshore hydrodynamics
David Andrew Barry, Roham Bakhtyar
Numerical investigations covering all the physical processes occurring in the surf and swash zones, including the cross-shore and longshore flows, have not been fully developed, although considerable work in 2D has appeared in recent years. However, given ...
2011Unsteady flow in a channel with large scale bank roughness
Systematic investigations on positive and negative surge waves from upstream have been conducted in a 40 m long channel with a mean bed slope of 1.14? and non-prismatic bank geometries. The channel banks included macro-roughness elements, namely various ca ...
Ed. Dittrich, Koll, Aeberle & Geisenhainer (eds)2010Numerical simulation of two-phase flow for sediment transport in the inner-surf and swash zones
David Andrew Barry, Roham Bakhtyar
A two-dimensional two-phase flow framework for fluid- sediment flow simulation in the surf and swash zones was described. Propagation, breaking, uprush and backwash of waves on sloping beaches were studied numerically with an emphasis on fluid hydrodynamic ...
Elsevier2010Competition between kinematic and dynamic waves in floods on steep slopes
We present a theoretical stability analysis of the flow after the sudden release of a fixed mass of fluid on an inclined plane formally restricted to relatively long time scales, for which the kinematic regime is valid. Shallow-water equations for steep sl ...
Cambridge University Press2010Numerical 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 ...
2009Numerical simulation of wave motion and its interaction with groundwater flow in coastal aquifers
David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar
Groundwater regime has an important role in coastal sediment transport near the coast and beach profile changes. Hitherto, accurate and complete nature of the interaction between wave motions, underground water and beach sediment transport is not yet known ...
2009Process-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, ...
2009Modeling 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 ...
2009Longshore sediment transport estimation using fuzzy inference system
Accurate prediction of longshore sediment transport in the nearshore is essential for the control of shoreline erosion and beach evolution. In this paper, the abilities of an hybrid Adaptive-Network-Based Fuzzy Inference System (ANFIS), a Fuzzy Inference S ...
