Porosity and dispersion constant calculations for a fractured carbonate aquifer using the two well tracer method

Journal Article · · Water Resour. Res.; (United States)

A method described uses the time-concentration profile from the discharging well of a labeled recharging- discharging well pair to evaluate an aquifer's porosity and dispersion constant. The technique is applicable for pulse tracer injection and recirculation. Derived equations allow prediction of streamline arc lengths and travel times between wells along streamlines. Adjacent streamlines joining the 2 wells define crescents that approximate dispersion columns of known length. The summation of breakthrough curve concentration profiles for flow through these individual columns provides a composite breakthrough curve for the entire flow field.
