The general tracing model of measuring flow velocity based on mass conservation

Tracer logging technique can accurately detect the velocity of groundwater seepage and the traditional point dilution is suitable for computing seepage velocity without vertical flow influence.This paper firstly introduces the research which is aimed to compute horizontal seepage velocity under the influence of vertical flow,and then pointes out that there are some unreasonable problems of the existing models.The authors rebuild the computing model of seepage velocity under the influence of vert
