“…The investigative framework of this research is based on the evaluation of the interdependent play among river basin geomorphologic, morphometric and hydrologic processes and features (e.g. Ivanov et al ., ; Martina and Entekhabi, ; Noto et al ., ) with specific regard to the application of the width function (WF) geomorphic approach (Marani et al ., ; Rodriguez‐Iturbe et al ., ; Rodríguez‐Iturbe and Rinaldo, ) also considering varying geomorphoclimatic (Graf, ; Rodriguez‐Iturbe and Valdes, ; Rodriguez‐Iturbe et al ., ; Naden, ; Di Lazzaro and Volpi, ; Volpi et al ., ) and urban settings (Veitzer and Gupta, ; Smith et al ., ; Ogden et al ., ) for providing flood risk managers and decision makers an accurate informative framework to develop safe river basin and urban area development and management plans (e.g. Cunha et al ., ; Faulkner et al ., ; Pedersen et al ., ; Ciervo et al ., ; Emanuelsson et al ., ).…”

The small ungauged basins of the highly urbanized area of the city of Rome are often the subject of critical flood conditions for the significant human‐made transformations. In this work the EBA4SUB framework, implementing the hydrogeomorphic width function instantaneous unit hydrograph rainfall run‐off model, and using digital elevation model, land use and synthetic precipitation as main input information, is applied for evaluating extreme hydrologic forcing conditions at the basic scale. The goal is to understand the rationale behind the observed increasing frequency of local urban inundations that are also observed in the uplands. Results present the impact of urbanization expressed by both the run‐off coefficient, the artificial drainage, impacted by paved surfaces and a dramatic number of river–road intersections (i.e. culverts), and the upstream to downstream non‐natural scaling behaviour of hydrologic parameters and in particular the peak discharge per unit drainage area.

“…As indicated by the red asterisks in all the panels of Figure , the storm velocity of the highest Q p (first column of the panels) is generally greater than that of the highest V run‐off (second column of the panels) except for the scenarios where storms travel along other directions than along the streamflow ( θ near 0) in Figure a,b. According to previous studies, the peak discharge is attributed not only to rainfall volume received by catchments, but also to spatial concentration of catchment rainfall (Nicótina, Alessi Celegon, Rinaldo, & Marani, ; Volpi et al, ). A higher spatial concentration of catchment rainfall essentially enhances the temporal superposition of run‐off contributing to the watershed outlet, which can be effectively indicated by a smaller standard deviation of run‐off timings, δ T .…”

“…First, the temporal dispersion of hydrographs ( δ T ) reach minimum when storms travel downstream along the main channel at a certain speed. This phenomenon is the so‐called “resonance condition” in literature (Seo et al, ; Surkan, ; Volpi et al, ). In essence, the resonance condition is caused by an exact superposition of the excess rainfall in time (Seo et al, ).…”

“…Seo, Schmidt, and Sivapalan () established a conceptual model based on peak timing of rainfall intensity in hydrologic response to investigate the effects of storm movement on peak discharges and analytically interpret the causes for varied peak responses from a moving storm. Volpi, Di Lazzaro, and Fiori () developed an analytical framework for analysing hydrologic response from a catchment under moving rainstorms by assuming time‐invariant of distribution of travel time within the basin.…”

“…Therefore, the Dynamic Moving Storm (DMS) generator here aims to provide generality in designing synthetic storms by allowing users to specify temporal change rate and the peak timing of rain intensity. In addition, most analytical frameworks used to study hydrologic responses to storm parameters assume time‐invariant flow velocity across the drainage network and thus neglect flow attenuation from channel routing (e.g., Gupta, Castro, & Over, ; Mandapaka, Krajewski, Mantilla, & Gupta, ; Seo et al, ., Volpi et al, ). Moreover, numerical modelling approaches in some aforementioned studies (e.g., De Lima & Singh, ; Lee & Huang, ; Singh, ; Stephenson, ) adopt kinematic wave approximation, which is incapable of modelling flow attenuation.…”

A synthetic storm generator—Dynamic Moving Storm (DMS)—is developed in this study to represent spatio‐temporal variabilities of rainfall and storm movement in synthetic storms. Using an urban watershed as the testbed, the authors investigate the hydrologic responses to the DMS parameters and their interactions. In order to reveal the complex nature of rainfall–run‐off processes, previously simplified assumptions are relaxed in this study regarding (a) temporal variability of rainfall intensity and (b) time‐invariant flow velocity in channel routing. The results of this study demonstrate the significant contribution of storm moving velocity to the variation of peak discharge based on a global sensitivity analysis. Furthermore, a pairwise sensitivity analysis is conducted to elucidate not only the patterns in individual contributions from parameters to hydrologic responses but also their interactions with storm moving velocity. The intricacies of peak discharges resulting from sensitivity analyses are then dissected into independent hydrologic metrics, that is, run‐off volume and standard deviation of run‐off timings, for deeper insights. It is confirmed that peak discharge is increased when storms travel downstream along the main channel at the speed that corresponds to a temporal superposition of run‐off. Spatial concentration of catchment rainfall is found to be a critical linkage through which characteristics of moving storms affect peak discharges. In addition, altering peak timing of rainfall intensity in conjunction with storm movement results in varied storm core locations in the channel network, which further changes the flow attenuation effects from channel routing. For future directions, the DMS generator will be embedded in a stochastic modelling framework and applied in rainfall/flow frequency analysis.

The effect of storm movement on infiltration, runoff and soil erosion in a semi‐arid catchment

Rainfall characteristics are key factors influencing infiltration and runoff generation in catchment hydrology, particularly for arid and semiarid catchments. Although the effect of storm movement on rainfall-runoff processes has been evaluated and emphasized since the 1960s, the effect on the infiltration process has barely been considered. In this study, a physically based distributed hydrological model (InHM) was applied to a typical semi-arid catchment (Shejiagou, 4.26 km 2) located in the Loess Plateau, China, to investigate the effect of storm movement on infiltration, runoff and soil erosion at the catchment scale. Simulations of 84 scenarios of storm movement were conducted, including storms moving across the catchment in both the upstream and downstream directions along the main channel, while in each direction considering four storm moving speeds, three rainfall depths and two storm ranges. The simulation results showed that, on both the hillslopes facing downstream (facing south) and in the main channel, the duration of the overland flow process under the upstream-moving storms was longer than that under the downstreammoving storms. Thus, the duration and volume of infiltration under upstream-moving storms were larger in these areas. For the Shejiagou catchment, as there are more hillslopes facing downstream, more infiltration occurred under the upstream-moving storms than the downstream-moving storms. Therefore, downstream-moving storms generated up to 69% larger total runoff and up to 351% more soil loss in the catchment than upstream-moving storms. The difference in infiltration between the storms moving upstream and downstream decreased as the storm moving speed increased. The relative difference in total runoff and sediment yield between the storms moving upstream and downstream decreased with increasing rainfall depth and storm speed. The results of this study revealed that the infiltration differences under moving storms largely influenced the total runoff and sediment yield at the catchment scale, which is of importance in runoff prediction and flood management. The infiltration differences may be a potential factor leading to different groundwater, vegetation cover and ecology conditions for the different sides of the hillslopes.
