“…Still, they constitute a physical framework to understand what and how generic features, such as geometry or boundary conditions, generate the RTD. They provide a link between observations and system's characteristics that can help in testing quickly different conceptual representations and help in understanding why real hydrologic systems deviate from reference simple ones (Eberts et al, 2012;Leray et al, 2012).

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.

Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. The mean transit time and whole stream residence time distribution are powerful metrics of catchment functioning, providing synoptic hydrological information such as water renewal time, heterogeneity of flowpaths, and overall water volume (Godsey et al., 2010;Hrachowitz et al., 2010; Marçais et al., 2015;McGuire and McDonnell, 2006;Van der Velde et al., 2012) . These hydrological parameters influence catchment biogeochemistry (Ocampo et al., 2006;Oldham et al., 2013;Pinay et al., 2015;Tetzlaff et al., 2007), further increasing their value as Constitution of a catchment virtual observatory for sharing flow and transport modelsObservatory for sharing models outputs Thomas et al. 4 indicators and predictors of catchment-scale water quality and chemistry. Because these parameters are of great general interest they feature prominently in the inputs and outputs of many models (e.g. McGuire et al., 2005;Tetzlaff et al., 2009a (Bishop et al., 2008). Small catchments express a wide diversity of subsurface flow configurations (Eberts et al., 2012;Gburek and Folmar, 1999;Sophocleous, 2002;Winter, 1999) depending on geological and topographical structures, distribution and timing of recharge, characteristics of the vadose zone, and free surface dynamics of the underlying aquifer (Bresciani et al., 2014;Schumann et al., 2010;Freer et al., 2002;Montgomery and Dietrich, 1989;O'loughlin, 1981;Šimŭnek et al., 2003;Voeckler et al., 2014; Dages et al., 2009; de Vries and Simmers, 2002;Scanlon et al., 2002).Observatory for sharing models outputs Thomas et al. 6 Perhaps most importantly in regards to catchment hydrology, small catchments are a convenient and powerful experimental unit. Compared to large catchments, there are fewer processes influencing behaviour of small catchments and collecti...

Shallow, old, and hydrologically insignificant fault zones in the Appalachian orogen

The permeability of fault zones impacts diverse geological processes such as hydrocarbon migration, hydrothermal fluid circulation, and regional groundwater flow, yet how fault zones affect groundwater flow at a regional scale (1-10 km) is highly uncertain. The objective of this work is to determine whether faults affect regional patterns of groundwater flow, by using radioactive radon and chloride to quantify groundwater discharge to lakes underlain by faults and not underlain by faults. We sampled lakes overlying the Paleozoic Appalachian fold and thrust belt in the Eastern Townships in Québec, and compared our results to a previous study in a crystalline watershed in the Canadian Shield. The field data was analyzed with an analytical geochemical mixing model. The uncertainties of model parameters were assessed in a sensitivity analysis using Monte Carlo simulation, and the difference between lakes tested with statistical analysis. While the model results indicate non-negligible groundwater discharge for most of the lakes in the Paleozoic orogen, the difference between the groundwater discharge rate into the lakes located on faults and the other lakes is not statistically significant. However, the groundwater discharge rate to lakes in the Paleozoic orogeny is significantly higher than lakes that overlay crystalline bedrock, which is consistent with independent estimates of permeability. The rate of groundwater discharge is not significantly enhanced or diminished around the thrust fault zones, suggesting that in a regional scale, permeability of fault zones is not significantly different from the bedrock permeability at shallow depth in this old, tectonically-inactive orogen.
