A good first approximation for the longitudinal dispersivity is to use a value of 10% of the transport distance [ 47 ], while Mallants et al. [ 48 ] provide the best estimate for the longitudinal dispersivity based on a few experimental ... evernote how to use

WebDispersive erosion depends on the chemistry of the clay on the one hand, and the dissolved salts in the pore and eroding water on the other. The presence of exchangeable sodium on clay mineral surfaces is one of the main chemical factors … WebDispersivity is allowed to vary temporally as a function of the mean travel distance of the solute from an input source. Various scale-dependent dispersivity relationships were presented including types which approach continuously to a maximum or asymptotic value.
