| Abstract: | Some method with lab-horizontal-soil-column was applied to measure hydrodynamic dispersion coefficient for clay.Base on the datum of moisture content in clay,we acquired the dispersion coefficient,and got the relation ship between hydrodynamic dispersion coefficient and mass moisture content.This approach has a clear physics concept and simple practical formula. |
