Numerical reconstruction and remediation of soil acidity on a one dimensional flow domain where the diffusion coefficient and advection velocity are exponentially dependent on time

Munene, Catherine M.; Onyango, Thomas T. M.; Muhavini, Cleophas (2019)

A one dimensional mass transport equation in porous medium whose solution is ill-posed is considered. Appropriate flow parameters that are consistent to flow of solutes are determined. Solutes diffusion coefficient and ...
Numerical reconstruction and remediation of soil acidity on a one dimensional flow domain with constant and linear temporally dependent flow parameters

Munene, Catherine M.; Onyango, Thomas T. M.; Muhavini, Cleophas (SCIENCEDOMAIN International, 2018)

A mathematical backward problem which involves solving a mathematical model based on a one dimensional advection - diffusion process of solute transport in a homogeneous soil structure is considered. The diffusion ...
Numerical reconstruction and remediation of soil acidity on a one dimensional flow domain with constant and linear temporally dependent flow parameters

Munene, Catherine M.; Onyango, Thomas T. M.; Muhavini, Cleophas (2018)

A one dimensional mass transport equation whose solution is ill-posed is considered to model flow of solutes in porous medium. The diffusion coefficient and advection velocity in the governing partial differential equation ...
