An optimality-based model of the coupled soil moisture and root dynamics (2008, unknown): “We calculated the seepage face ﬂow ( Q sf , m s − 1 ) following Reggiani et al. (2000): The parameter γ 0 is the average slope angle of the seepage face (set to 0.033 radians (=1.9 degrees) in this study), while s is a typical horizontal length scale, which depends on the length of the hillslope.”
Towards an alternative blueprint for a physically based digitally simulated hydrologic response modelling system (2002, methodology): “The theory does not depend on these particular constitutive relationships and Reggiani et al. (1999, 2000) stress that other forms could be used where more appropriate.”
Extension of the representative elementary watershed approach for cold regions via explicit treatment of energy related processes (2006, methodology): “…transpiration is combined with evaporation and is deemed as a phase transition from liquid to vapor which occurs within the u-zone, i.e., the soil (Reggiani and Sivapalan, 2000; Reggiani and Rientjes, 2005; Lee et al., 2005b, 2006), which differs from the actual vaporization process occurring…”
Subsurface flow contribution in the hydrological cycle: lessons learned and challenges ahead—a review (2013, unknown): “Meanwhile, it is worth mentioning that some alternative concepts such as Representative Elementary Watersheds (Reggiani et al. 1998, 2000; Zhang and Savenije 2005) or Hydrological Response Units (Kouwen et al. 1993; Flugel 1995; Viviroli et al. 2009) have been introduced.”
On explanatory depth and predictive power (2001, background): “Neither can be easily validated in open systems and cannot even be applied except by making certain closure assumptions (e.g. see Reggiani et al. (2000)).”
On the colour and spin of epistemic error (and what we might do about it) (2011, background): “The analysis of recession curves has a long history in hydrology and extensive reviews have been provided by Hall (1968) and Tallaksen(1995). In spite of well-known difficulties with recession variability and partitioning of flow sources, an analysis of recession curves can often give some indicatio”
Towards reconstruction of the flow duration curve: development of a conceptual framework with a physical basis (2011, methodology): “The water balance model by Reggiani et al. (2000) consists of three coupled governing equations: mass balance in the unsaturated zone, momentum balance in the unsaturated zone, and mass balance in the saturated zone, as shown in Eqs.”
Predictions of rainfall-runoff response and soil moisture dynamics in a microscale catchment using the CREW model (2006, methodology): “Finally, as in Reggiani et al. (2000), the actual infiltration flux (euc) during rainfall events can be expressed as: euc = min [ iωu, f ∗ωu ] (14) wherei is rainfall intensity andωu is the surface area fraction occupied by the unsaturated zone.”
Towards a coherent philosophy for modelling the environment (2002, background): “Formulating the balance equations is itself a significant task (e.g. Reggiani et al., 1998, 1999, 2000); defining the coefficients that control the fluxes in those equations to reflect the particular characteristics of particular places with any precision is effectively still beyond us (Beven,…”
