摘要:	This work presents a two-well method to evaluate transverse dispersion coefficients for tracer tests conducted in a radially convergent flow field. A two-dimensional mathematical model is derived and applied to illustrate how transverse dispersion influences tracer transport in a convergent radial tracer test. A curve-fitting procedure is proposed to evaluate simultaneously the longitudinal and transverse dispersivities. A hypothetical experiment is used to demonstrate the application of the method. The proposed method allows one to evaluate the transverse dispersivity from field tracer tests, as long as the observed breakthrough curves at the pumping well and an observing well are known.
