Descrição: The self-organisation of groundwater flow in nested systems as revealed and defined by Tth (1963) is arguably one of the most fundamental properties of groundwater flow. Despite that, the theoretical characteristics of nested groundwater flow systems have mostly been studied under restricted modelling conditions. Overwhelmingly, from Tths (1963) original analysis till recent works (e.g. Wang et al. 2014; Zech et al. 2016), a specified-head top boundary condition has been used for representing the water table, often further assuming that the latter could be approximated by the land surface topography. While important insights can be gained using this undeniably convenient approach, the authors of this essay propose that specifying the hydraulic head along the top boundary can induce important errors in the flow solution, and that the water table would be better viewed as a variable function of the systems properties and stresses. It is argued that more research needs to be conducted on nested groundwater flow systems under conditions where the water table is not specified.
