DETERMINING THE TURNOVER TIME OF GROUNDWATER SYSTEMS WITH THE AID OF ENVIRONMENTAL TRACERS 1. Models and Their Applicability
P. Małoszewski,A. Zuber +1 more
TL;DR: In this paper, three new lumped-parameter models have been developed for the interpretation of environmental radioisotope data in groundwater systems, and the applicability of these models were tested by the reinterpretation of several known case studies (Modry Dul, Cheju Island, Rasche Spring and Grafendorf).
Journal ArticleDOI
On the physical meaning of the dispersion equation and its solutions for different initial and boundary conditions
TL;DR: In this article, it is shown that similarly to the movement in capillaries, also in other dispersive systems, the distinction between the concentration of solute in res is also made by known and new transformations.

Lumped parameter models for the interpretation of environmental tracer data
Piotr Maloszewski,Andrzej Zuber +1 more
TL;DR: In this article, the applicability of the lumped-parameter approach for the interpretation of tracer data is discussed for a steady-state flow approximation, and a user-friendly computer program is given.
