A Modified Groundwater Flow Model Using the Space Time Riemann-Liouville Fractional Derivatives Approximation

open access: yesAbstract and Applied Analysis, 2014
The notion of uncertainty in groundwater hydrology is of great importance as it is known to result in misleading output when neglected or not properly accounted for. In this paper we examine this effect in groundwater flow models.

Numerical Algorithms for the Fractional Diffusion-Wave Equation with Reaction Term

open access: yesAbstract and Applied Analysis, 2013
Two numerical algorithms are derived to compute the fractional diffusion-wave equation with a reaction term. Firstly, using the relations between Caputo and Riemann-Liouville derivatives, we get two equivalent forms of the original equation, where we ...
