As a result of definitions made in sections (4) and (5) two relations exist involving q(t,tin), i.e.
equations (11) and (30), and aeT (t,tin), i.e. equations (12) and (31). Equating the corresponding
two expression, results in:

3.1 Watershed partition
Pertinent to our approach is the use of a coarse degree of spatial information, at the level of the hydrologic response units
(HRUs). These HRUs groups a set of hydrologically similar points close each other, that are treated as a single unit, on the
basis of mathematical, physical or computational arguments. In other words, even if information can be calculated at pixels
level, for instance for exploiting the accurate knowledge of topography, this information is subsequently coarse grained for5
getting single values for any HRU. The rationale of this choice is to capture the ’meaningful’ spatial heterogeneity in the input
data and processes, similar to that adopted in other models (Lagacherie et al., 2010; Ascough et al., 2012). More specifically,
in NewAGE the basin is partitioned into hillslopes and channel links. This partition is carried out according the procedure
presented in Formetta et al. (2014b, 2011). Each hillslope and link is numbered according to the Pfafstetter scheme (Formetta
et al., 2014a; Abera et al., 2014), which defines an identifier for each link and hillslope, and an order to transverse them.10
Eventually, this approach allows the resolution of Eq. (1) for any of these units independently, from the most uphill one to
the outlet. However, depending on the process, the value of each term in the equation can depend on some sub-HRU analysis.
In this paper, the term hillslope, HRU, and subbasin are used alternatively for the same basin partitioning concept. A total of
42 HRUs is chosen for the basin (figure 1b). To illustrate the variability of hydrological quantities among HRUs, a sample of
HRUs (four HRUs: Id 1, 4, 13, and 37) are systematically selected to represent different elevation (elevation ranges from 65615
