Discussion of 'Diagnostic curve for confined aquifer parameters from early drawdowns' by Sushil K. Singh

The determination of aquifer parameters is fundamental to groundwater resources assessment. This important topic has received much attention in the literature over many years. Singh (2008) presented a method for determination of parameters for an ideal con ...

Buffering soil-water acidity in chlorinated solvent bioremediation schemes

Christof Holliger, David Andrew Barry, Alessandro Brovelli, Clare Robinson, Elsa Marina Lacroix

Chlorinated solvents form a significant part of groundwater contamination worldwide. They are difficult to remove via physical means, and anaerobic source-zone remediation based on provision of fermentable e-donor is an attractive clean-up dechlorination o ...

Effect of raindrop splash and transversal width on soil erosion: Laboratory flume experiments and analysis with the Hairsine-Rose model

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

The parameter consistency of the one-dimensional Hairsine-Rose (H-R) erosion model under conditions of significant rainfall splash was examined. To account for the splash characteristic length scale and its interaction with the transverse erosion width, ex ...

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 ...

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 ...

Comment on 'An analytic solution of capillary rise restrained by gravity' by N. Fries and M. Dreyer

David Andrew Barry, Laurin Wissmeier

The porous medium model of Green and Ampt, describing flow in porous media, appeared earlier than the capillary model of Washburn, although both lead to the mathematically identical models. The model of Green and Ampt is related to the Washburn model by an ...

Optimization of cascade stilling basins using GA and PSO approaches

David Andrew Barry, Roham Bakhtyar

In high head dams, the kinetic energy at the spillway toe is very high and the tail-water depth available for energy dissipation is relatively small. Cascade stilling basins are energy dissipation systems for high head dams, the design of which is based on ...

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 ...

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, ...

Effects of crab burrows on pore water flows in salt marshes

David Andrew Barry

Macro-pores such as crab burrows are found commonly distributed in salt marsh sediments. Their disturbance on the soil structure is likely to influence both pore water flows and solute transport in salt marshes; however, the effects of crab burrows are not ...

Comment on 'The effect of evaporation on the wicking of liquids into a metallic weave' by N. Fries, K. Odic, M. Conrath and M. Dreyer

David Andrew Barry, Laurin Wissmeier

A recent paper reported capillary rise and evaporation experiments in metallic wicks, as well as a mathematical model. The authors found a consistent discrepancy between the model predictions and data: The model over-predicted the capillary height rise by ...

Euler–Euler coupled two-phase flow modeling of sheet flow sediment motion in the nearshore

David Andrew Barry, Roham Bakhtyar

A two-dimensional numerical model was presented for the simulation of sediment transport under oscillatory sheet flow conditions in the nearshre zone. Most existing mathematical models for predicting sediment transport in this area are based on the governi ...

Design tool for estimation of buffer requirement for enhanced reductive dechlorination of chlorinated solvents in groundwater

David Andrew Barry, Clare Robinson

To assist in the design of enhanced reductive dechlorination systems for in situ remediation of chlorinated solvent source zones, the software BUCHLORAC (BUffering of deCHLORination ACidity) was developed to predict the amount of buffer required to maintai ...

Effect of mineral reactions on the hydraulic properties of unsaturated soils: Model development and application

David Andrew Barry, Laurin Wissmeier

The selective radius shift model was used to relate changes in mineral volume due to precipitation/dissolution reactions to changes in hydraulic properties affecting flow in porous media. The model accounts for (i) precipitation/dissolution taking place on ...

Bioclogging in porous media: Model development and sensitivity to initial conditions

Flavio Malaguerra, David Andrew Barry, Alessandro Brovelli

This work presents a numerical model able to simulate the effect of biomass growth on the hydraulic properties of saturated porous media, i.e., bioclogging. A new module for an existing coupled flow and reactive-transport code -- PHWAT -- was implemented. ...
