Item type:Publication, A numerical computation of the non-dimensional form of a non-linear hydrodynamic model in a uniform reservoir(2009-11-01)A mathematical model is used to simulate the water current and the elevation in a uniform reservoir. A non-linear hydrodynamic model that provides the velocity field and elevation of the water flow is considered. In the simulating process, the Lax-Wendroff technique is used to approximate the solutions. The numerical solution can be the input data for a water-quality model that is applicable for the optimal control of water treatment in the system to achieve minimum cost. © 2009 Elsevier Ltd.

Item type:Publication, A numerical computation of a non-dimensional form of stream water quality model with hydrodynamic advection-dispersion-reaction equations(2009-11-01)Mathematical models of water quality assessment problems often arise in environmental science. The modelling often involves numerical methods to solve the equations. In this research, two mathematical models are used to simulate pollution due to sewage effluent in the nonuniform flow of water in a stream with varied current velocity. The first is a hydrodynamic model that provides the velocity field and elevation of the water flow. The second is a dispersion model, where the commonly used governing factor is the one-dimensional advection-dispersion-reaction equation that gives the pollutant concentration fields. In the simulation processes, we used the Crank-Nicolson method system of a hydrodynamic model and the backward time central space scheme for the dispersion model. Finally, we present a numerical simulation that confirms the results of the techniques. © 2009 Elsevier Ltd. All rights reserved. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A numerical computaion of non-linear hydrodynamic model(2009-12-01)Water pollution assessment problems arise frequently in environmental science. The hydrodynamic model is used to simulated current in the reservoir that provides the velocity and height of the water. In this research, the numerical computation of velocity and water elevation in two-dimensional non-linear hydrodynamic model is considered. The simulating processes, the Lax-Wendroff method is used to solve the model. The accuracy of the models is tested by the illustrative example.
