“…Surface water flooding (SWF), also known as pluvial flooding, is a global hazard. For example, parts of Europe (Germany; Bung, Oertel, Schlenkhoff, & Schlurmann, ; and Italy; Di Salvo, Ciotoli, Pennica, & Cavinato, ) and Asia (Japan; Bhattarai, Yoshimura, Seto, Nakamura, & Oki, ; and India; Akilan, Balaji, Abdul Azeez, & Satyanarayanan, ) have all experienced SWF in recent years. SWF occurs when rainwater cannot drain away quickly enough through drainage systems or by soaking into the ground; instead, water lies on or flows over the ground.…”

Surface water flooding (SWF) is a recurrent hazard that affects lives and livelihoods.Climate change is projected to change the frequency of extreme rainfall events that can lead to SWF. Increasingly, data from Regional Climate Models (RCMs) are being used to investigate the potential water-related impacts of climate change; such assessments often focus on broad-scale fluvial flooding and the use of coarse resolution (>12 km) RCMs. However, high-resolution (<4 km) convection-permitting RCMs are now becoming available that allow impact assessments of more localised SWF to be made.At the same time, there has been an increasing demand for more robust and timely real-time forecast and alert information on SWF. In the UK, a real-time SWF Hazard Impact Model framework has been developed. The system uses 1-km gridded surface runoff estimates from a hydrological model to simulate the SWF hazard. These are linked to detailed inundation model outputs through an Impact Library to assess impacts on property, people, transport, and infrastructure for four severity levels.Here, a set of high-resolution (1.5 km and 12 km) RCM data has been used as input to a grid-based hydrological model over southern Britain to simulate Current (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) and Future (~2100s; RCP8.5) surface runoff. Counts of thresholdexceedance for surface runoff and precipitation (at 1-, 3-and 6-hr durations) are analysed. Results show that the percentage increases in surface runoff extremes, are less than those of precipitation extremes. The higher-resolution RCM simulates the largest percentage increases, which occur in winter, and the winter exceedance counts are greater than summer exceedance counts. For property impacts, the largest percentage increases are also in winter; however, it is the 12-km RCM output that leads to the largest percentage increase in impacts. The added-value of highresolution climate model data for hydrological modelling is from capturing the more intense convective storms in surface runoff estimates.

“…The detailed and complete view of the geo-hydrological hazard in a critical area like Genova Municipality is an important tool for decision makers to plan and for adopting the more adequate activities for risk mitigation and reduction (Di Salvo, Ciotoli, Pennica, & Cavinato, 2017;Borrelli & Muto, 2017;Conforti, Muto, Rago, & Critelli, 2014;Nicu, 2017a;.…”

Inventory of geo-hydrological phenomena in Genova municipality (NW Italy)

In Italy geo-hydrological phenomena are the most common hazards: every year landslides and floods cause damage and fatalities; Genova city is one of the most affected areas. Since 2000 scientific studies have demonstrated an increase in events, due to the rainfall regime variation and to the urbanization. Thematic maps are an essential tool for evaluating the interaction between geomorphological processes and the elements at risk. In the present work, we have prepared an original geo-hydrological phenomena inventory map of Genova at 1:45,000 scale (the 'A1' size). The map shows the floodable areas, landslides and deepseated gravitational slope deformation, the urban fabric and the cultural heritage sites. The map gives an overview of the geo-hydrological phenomena through the integration of the different hazard sources, of the exposed elements and of their spatial distribution, allowing for a first analysis of the risk: in a 240 km 2 area, more than 3600 residential buildings are located on the 4 km 2 high hazard floodable areas and more than 360 on the about 500 active landslides.

“…Furthermore, urban growth induces the realization of engineered drainage systems with the sealing of natural surfaces and streams (increasing surface water runoff) and the underground channeling of the natural drainage network (Di Salvo et al, 2017). This might worsen hydraulic hazards.…”

Geomorphology of landslide–flood-critical areas in hilly catchments and urban areas for EWS (Feltrino Stream and Lanciano town, Abruzzo, Central Italy)

Urban and small catchment landslides and floods are common types of hazards caused by intense rainfall. The detailed geomorphological mapping and analysis of the superficial hydrographic network are fundamental tools to assess the geo-hydrologically critical areas. In this study, the Feltrino Stream and Lanciano area (Adriatic coastal-hills) were investigated through a basinscale and urban-scale geomorphological analysiswhich incorporated temperature-rainfall and morphometric analyses, and the acquisition of geomorphological and hazard data, integrated with geomorphological fieldwork and mapping. The creation of a geodatabase and the data overlay led to assess the landslide-flood critical areas through geomorphology-based matrices. This study aimed to define the distribution of landslide-flood historical/recent events and related critical areas for the realization of an urban EWS, composed of a network of nine gauges, integrating the existing regional monitoring network. It defined a local alert system for landslide-flood and could support real-time communication for civil protection purposes.
