The document discusses advancements made in hydrological modeling, particularly focusing on the Adige database and the application of the NewAge model in various catchment areas. It details the methodology of partitioning watersheds into hydrologically similar response units to enhance accuracy. Additionally, it outlines ongoing research and potential future projects related to water management and modeling in Italy.

The location of the Posina basin in the Northeast of Italy (a) and DEM elavation, location of rain gauges and hydrometer stations, subbasin-channel partitions used for in the simulation (b). 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 5
