Numerical Solution of Fractional Advection-Dispersion Equation
Publisher: American Society of Civil Engineers
Abstract: Numerical schemes and stability criteria are developed for solution of the one-dimensional fractional advection-dispersion equation (FRADE) derived by revising Fick’s first law. Employing 74 sets of dye test data measured ...
Diffusion-Based Semi-Infinite Fourier Probability Distribution
Publisher: American Society of Civil Engineers
Abstract: A multitude of natural processes occurring in environmental and water resources are diffusive processes, and their observations exhibit a natural lower bound of zero and practically no upper bound. Such processes can be ...
Longitudinal Dispersion Coefficient in Straight Rivers
Publisher: American Society of Civil Engineers
Abstract: An analytical method is developed to determine the longitudinal dispersion coefficient in Fischer's triple integral expression for natural rivers. The method is based on the hydraulic geometry relationship for stable rivers ...
Environmental Factors Influencing the Abundance of Enterococci in Gulf Coast Beach Waters
Publisher: American Society of Civil Engineers
Abstract: Enterococci concentrations in seawater samples collected in 2010 at a Gulf Coast beach in the afternoon were significantly lower (
Fractional Kinetic Model for First Flush of Stormwater Pollutants
Publisher: American Society of Civil Engineers
Abstract: By generalizing the urban ground as a fractal surface and revising the classical Fick’s formula as a law of dispersion with a fractional-order derivative, a fractional kinetic model is developed for simulation of the first ...
