“…Moving to a broader context, the literature suggests that among the factors that govern the catchment's hydrological response during the process of rainfall-runoff transformation, the catchment's geomorphological features have been well represented (see, e.g., Nagy et al, 2021;Ravazzani et al, 2019). The synthesis of the basin response function from physical basin characteristics becomes crucial in ungauged catchments (Singh et al, 2013).…”

Abstract. Here we present FOCA (Italian FlOod and Catchment Atlas), the first systematic collection of data on Italian river catchments for which historical discharge time series are available. Hydrometric information, including the annual maximum peak discharge and average daily annual maximum discharge, is complemented by several geomorphological, climatological, extreme rainfall, land-cover and soil-related catchment attributes. All hydrological information derives from the most recently released datasets of discharge and rainfall measurements. To enhance the reproducibility and transferability of the analysis, this paper provides a description of all the raw data and the algorithms used to build the basin attribute dataset. We also describe the approaches adopted to solve problems encountered during the digital elevation model elaboration in areas characterized by a complex morphology. Details about the data quality-control procedure developed to detect and correct errors are also reported. One of the main novelties of FOCA with respect to other national-scale datasets is the inclusion of a rich set of geomorphological attributes and extreme rainfall features for a large set of basins covering a wide range of elevations and areas. Using this first nationwide data collection (available at https://doi.org/10.5281/zenodo.10446258, Claps et al., 2023), a wide range of environmental applications, with a particular focus on flood studies, can be undertaken within the Italian territory.

“…For the sensitivity analyses storm duration were selected that are close the calibrated around 2 h time of concentration of each sub-watershed. 1% frequency event was chosen to better represent possible impacts of climate change and comply with Hungarian design standards [14,15]. The intensity vs. time function was defined with a triangular distribution.…”

Rainfall duration and parameter sensitivity on flash-flood at a steep watershed

The common feature of streams in steep sloping watersheds is that there is a significant change from base-flow to flash-flood; sometimes two or three orders of magnitude. In Hungary, these streams are usually ungauged, with lack of available data, and models. The watershed features both urban and natural land use conditions, but the main area is quite homogenic.This paper evaluates the impact of different model parameterizations, and rainfall duration on flash-flood events in the Morgó-creek watershed. The goal is to find the main parameters that can represent the uncertainty of a flash-flood sensitive area, and how the calibrated and determined parameters take effect on a model if these values are shifted on given intervals.
