A New Method for Laboratory Estimation of the Transverse Dispersion Coefficient

Abstract: We introduce a method for identifying the transverse dispersion coefficient in laboratory experiments based on the analytical solution of a pulse injection of a nonreactive solute in a soil column (cylindrical geometry) packed with a homogeneous porous medium. This method takes into account the effect of boundary conditions such as no flux on the column perimeter, and it does not need a priori knowledge of the longitudinal dispersion coefficient. Numerical applications of the method show that it is stable and … Show more

“…Massabò et al (2007) introduced a quick method for estimating the transverse dispersion coefficient in laboratory experiments without a priori knowledge of the longitudinal dispersion coefficient. The method is based on the analytical solution of the advective‐dispersion equation (ADE) given in Massabò et al (2006) for a pulse injection of a nonreactive solute in a soil column.…”

“…Gracias a ello, se han podido realizar investigaciones sobre las desviaciones del comportamiento real de solutos frente al modelo teóri-co (Rovey y Niemann, 2005) o como forma de proporcionar datos a los que enfrentar nuevos modelos matemáticos de flujo y transporte que adopten enfoques más integrales (Massabò y Catania, 2007). La posibilidad de realizar pruebas en laboratorio de nuevos dispositivos y estrategias de remediación de acuíferos contaminados son también una aplicación habitual para la que se construyen estos modelos (Christ, Abriola, 2006).…”

“…An infinite transport system enables the upward movement of the tracer mass and causes a backward dispersion at the inlet boundary. Commenting on the work of Massabò et al (2007) and Chen et al (2012a) argued that their analytical solution is unsuitable for interpreting their two-dimensional radial column experiment because it inadequately describes the actual solute transport process in the soil column. Zhang et al (2006) described an in-situ infiltration tracer test for simultaneously estimating the longitudinal and transverse dispersion coefficients and derived an analytical solution to a 2D ADE in cylindrical coordinates.…”

“…Recently, various field and laboratory methods have been developed for simultaneously determining the longitudinal and transverse dispersion coefficients in unsaturated soil. Massabò et al (2007) proposed a technique for determining the longitudinal and transverse dispersion coefficients from the BTCs of a laboratory-scale column experiment. Massabò et al (2006) developed an analytical solution for twodimensional advective-dispersive transport in a radial geometry for interpreting the results of laboratory-scale column experiments.…”
