“…It is only applicable for a few cases, typically for homogeneous confined aquifers with possibly varying thickness (Etcheverry, 2001), aquitards where mass transfer with the surroundings compartments can be neglected (Bethke and Johnson, 2002;Castro et al, 1998), highly localized samplings close to the system inlet (Leray et al, 2012;Marçais et al, 2015), or fractured and karst systems (Bockgård et al, 2004;Burton et al, 2002;Knowles et al, 2010;Long and Putnam, 2006;Long and Putnam, 2009). …”

Analytical solutions are often adopted as a model of the RTD and a broad spectrum of models from many disciplines has been applied. Although these solutions are typically reduced in dimensionality and limited in complexity, their ease of use makes them preferred tools, specifically for the interpretation of tracer data. Our review begins with the mechanistic basis for the governing equations, highlighting the physics for generating a RTD, and a catalog of analytical solutions follows. This catalog explains the geometry, boundary conditions and physical aspects of the hydrologic systems, as well as the sampling conditions, that altogether give rise to specific RTDs. The similarities between models are noted, as are the appropriate conditions for their applicability. The presentation of simple solutions is followed by a presentation of more complicated analytical models for RTDs, including serial and parallel combinations, lagged systems, and non-Fickian models. The conditions for the appropriate use of analytical solutions are discussed, and we close with some thoughts on potential applications, alternative approaches, and future directions for modeling hydrologic residence time.

“…A transit time distribution for the Poltringen wells was obtained by fitting a lumped parameter model to the observed time series of environmental tracers. The dispersion model was previously applied for karstified aquifers (Maloszewski et al 2002;Long and Putnam 2006). For our application, a dispersion model was fitted as it can accommodate most hydrogeological settings and it can also account for several mixing processes (Małoszewski and Zuber 1982).…”

For karstified aquifer systems, numerical models of groundwater flow are difficult to setup and parameterize. However, a system understanding useful for groundwater management may be obtained without applying overly complicated models. In this study, we demonstrate for a karstified carbonate aquifer in south-western Germany that a combination of methods with moderate data requirements can be used to infer flowpaths and transit times of groundwater to production wells.
