A fractional dispersion model for overland solute transport
(American Geophysical Union, 2006-03-18)
Using the kinematic-wave overland flow equation and a fractional dispersion-advection equation, a process-oriented, physically-based model is developed for overland solute transport. Two scenarios, one consisting of downslope ...
Downstream hydraulic geometry relations: 2. Calibration and testing
(American Geophysical Union, 2003-12-04)
Using 456 data sets under bank-full conditions obtained from various sources, the geometric relations, derived in part 1 [ Singh et al., 2003 ], are calibrated and verified using the split sampling approach. The calibration ...
Longitudinal Dispersion Coeffiient in Straight Rivers
(2001-11)
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 ...
Numerical Solution of Fractional Advection-Dispersion Equation
(2004-05-01)
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 ...
