Article
Riverbank filtration system is a technique used for surface water treatment that is based on biological activities to attenuate the contamination in water through its movement from the river to the adjacent pumping well. Hydraulic conductivity is a critical parameter that affects the efficiency of riverbank filtration systems. In this study, an ana...

Modeling three-dimensional contaminant transport released from arbitrary shape source geometries is useful in hydrological and environmental sciences. This article produces several analytical solutions for three-dimensional contaminant transport in a homogeneous and isotropic aquifer by using Green’s function with the groundwater flow which is assu...
Article
Full-text available
Riverbank filtration system is considered one of the economic and sustainable solutions to river water pollution especially in tropical countries such as Malaysia. In this work, an analytical model is developed to simulate the contaminant attenuation in riverbank filtration systems by using the separation of variables method. The basic aim of the m...

This study consider the development of three dimensional analytical solutions for contaminant transport induced by a pumping well near a stream. The solutions were derived for both line-width and finite-width streams based on Green’s function approach. These solutions were implemented in an aquifer that was partially penetrated by the stream and we...
Article
This article provides an analytical solute transport model to investigate the potential of groundwater contamination by polluted surface water in a two dimensional domain. The clogging of streambed which makes the aquifer partially penetrated by the stream, is considered in the model. The impacts of pumping process, hydraulic conductivity and clogg...
Article
The present study investigates the characteristics of calcium hardness removal from water using a continuous flow microwave (MW) radiation system with heat exchange. The effects of initial calcium concentration, detention time, and initial temperature were investigated by the study. About 97% of calcium hardness removal was achieved at a detention...

The presence of different sorts of nutrients in wastewater raises the concern on adopting effective treatment techniques, to prevent potential adverse impacts on the environment’s components, as well as to recycle nutrients for useful applications. Nitrogen is a popular nutrient that often existed abundantly in landfill leachate. Struvite (MgNH4PO4...
Article
A mathematical model is presented for the thin-film flow of Johnson-Segalman fluid through porous medium down an inclined plate under steady-state flow. The developed model is based on modified Darcy's law for viscoelastic fluid. The nonlinear equation derived from the model is solved using the Adomian decomposition method to obtain an approximate...

Riverbank filtration (RBF) system is a surface water technology that is based on the natural treatment of filtration instead of the use of chemicals, to pretreat surface water and provides public water supplies. Hydraulic conductivity value is one of the significant factors affecting the water quality in RBF systems.In this article, an analytical m...

Subsea cable laying process is a difficult task for an engineer due to many uncertain situations which occur during the operation. It is very often that the cable being laid out is not perfectly fit on the route being planned, which results in the formation of slack. In order to control wastages during installation, the slack needs to be minimized...

In this article, the non-linear equation of unsteady flow of Powell-Eyring fluid is solved by using Adomian Decomposition Method (ADM). The fluid is assumed to be flowing under the effect of magnetic field. The model is developed for the case of constant accelerated plate. Sensitivity analysis is performed to show the effects of material parameters...

Riverbank filtration (RBF) is a surface water technology that is based on the natural treatment of filtration instead of the use of chemicals, to pre-treat surface water and provides public water supplies. Hydraulic conductivity value is one of the significant factors affecting the water quality in RBF systems. In this article, an analytical modell...
Conference Paper
Riverbank filtration system is river water treatment approach based on natural removal of contaminants due to physical, chemical and biological processes. In this article, an analytical model is developed by using Green’s function method to simulate the effects of pumping well and microbial activity that occurs in riverbed sediments on contaminant...
Article
Analytical study of the influence of both the pumping well discharge rate and pumping time on contaminant transport and attenuation is significant for hydrological and environmental science applications. This article provides an analytical solution for investigating the influence of both pumping time and travelling time together for one-dimensional...
Conference Paper

Riverbank filtration (RBF) is a natural technique for surface water treatment, based on the natural removal of pollutants from water during its transfer through the aquifer to pumping well. In this report a mathematical model is used to simulate three major processes related to RBF which are: (1) Groundwater flow and contaminants transport from riv...

Full-text available
Riverbank filtration (RBF) technology is applied in several countries around the world as one of the main sources of drinking water supply both from quantitative and qualitative point of view. Consequently, several analytical modelling methods, mostly based on the transformation techniques, are developed in literature to describe different processe...
