In this work, we present a review of the GILTT (Generalized Integral Laplace Transform
Technique) solutions for the one and two-dimensional, time-dependent, advection–diffusion …

Atmospheric air pollution turbulent fluxes can be assumed to be proportional to the mean
concentration gradient. This assumption, along with the equation of continuity, leads to the …

Sudden water pollution accidents in surface waters occur with increasing frequency. These
accidents significantly threaten people's health and lives. To prevent the diffusion of …

Transient mass-transfer phenomena occurring in natural and engineered systems consist of
convection, diffusion, and reaction processes. The coupled phenomena can be described by …

According to the hydrodynamic dispersion theories, the dispersion parameter is proportional
to a power n of the velocity; the power ranges between 1 and 2. Based on the value n= 1 …

All numerical codes developed to solve the advection–diffusion-reaction (ADR) equation
need to be verified before they are moved to the operational phase. In this paper, we initially …

One-dimensional model describing contaminant concentration pattern, governed by
advective-diffusive process, is discussed in the present chapter. Solute mass dispersion …

This paper presents a new semianalytical approach for the solution of suspended sediment
transport in channels under uniform conditions using generalized integral transform …

In atmospheric environments, traditional differential equations do not adequately describe
the problem of turbulent diffusion because the usual derivatives are not well defined in the …

An advection-diffusion equation for a ground-level finite area source is solved analytically in
a closed form using the superposition method. Power laws are assumed for height …
