| Abstract: | According to the principle of mass conservation for tracer, the formula for calculating horizontal velocity in aquifer is deduced by adopting the single test well technology and considering the dispersion effect. The application of this method indicates that the horizontal flow velocity significantly affects the calculation result when strong vertical flow exists, so that the dispersion effect can not be ignored. |

| Keywords: | generalized dilution formula aquifer test well tracer technique seepage vertical flow |
