Data to the models of migration pollutants in aquifers are obtained primarily through laboratory column tests. One tools support experiment planning and interpretation is sensitivity analysis. The analysis facilitates identifying output-input relationship particular models, which, case tests, involves determining dependence shape a tracer breakthrough curve on modeled processes introduced transport sorption parameter values. This article presents for conservative tracer, which subject advection, diffusion, dispersion processes, reactive (nonconservative) additionally equilibrium or nonequilibrium (i.e., single models). study introduces set pulse descriptors (indicators) that enable quantitative comparison influence various parameters' values shape. authors propose an algorithm, based descriptors, selecting model appropriate results also contains specification from literature review related selected theoretical research. conducted allowed (1) identify parameters with most significant shape, (2) depiction tracer's incomplete recovery, (3) select tail-form asymmetry visible.
