“…The integration of individual decisions and coping capacities enables us to shift from exposure measurement to social vulnerability quantification (Terti et al, 2015). To advance in this direction, the use of welldescribed, geolocalized, time-stamped and reliable human impact datasets is needed for model verification (Terti et al, 2017).…”

“…Therefore, several vehicle-related accidents occur during flash floods. Death circumstances investigations showed that in postindustrial countries over half of flood victims are motorists trapped by road flooding (Ashley and Ashley, 2007;Sharif et al, 2012;Terti et al, 2017). Hence, daily mobility is pointed out as one of the primary causes of population exposure and vulnerability to flash floods (Ruin, 2010).…”

“…Results showed that people are potentially at risk in the daytime period. In the context of flash floods, Terti et al (2015Terti et al ( , 2017 and Spitalar et al (2014) showed that daily and sub-daily variation of population dis-tribution may provide an appropriate assessment of human exposure to such short-fuse weather events.…”

Abstract. Recent flash flood impact studies highlight that road networks are often disrupted due to adverse weather and flash flood events. Road users are thus particularly exposed to road flooding during their daily mobility. Previous exposure studies, however, do not take into consideration population mobility. Recent advances in transportation research provide an appropriate framework for simulating individual travelactivity patterns using an activity-based approach. These activity-based mobility models enable the prediction of the sequence of activities performed by individuals and locating them with a high spatial-temporal resolution. This paper describes the development of the MobRISK microsimulation system: a model for assessing the exposure of road users to extreme hydrometeorological events. MobRISK aims at providing an accurate spatiotemporal exposure assessment by integrating travel-activity behaviors and mobility adaptation with respect to weather disruptions. The model is applied in a flash-flood-prone area in southern France to assess motorists' exposure to the September 2002 flash flood event. The results show that risk of flooding mainly occurs in principal road links with considerable traffic load. However, a lag time between the timing of the road submersion and persons crossing these roads contributes to reducing the potential vehicle-related fatal accidents. It is also found that sociodemographic variables have a significant effect on individual exposure. Thus, the proposed model demonstrates the benefits of considering spatiotemporal dynamics of population exposure to flash floods and presents an important improvement in exposure assessment methods. Such improved characterization of road user exposures can present valuable information for flood risk management services.

“…Hourly precipitation extremes have received much attention due to the hazards they pose to human lives and infrastructure (Ashley and Ashley 2008;Terti et al 2017). Widespread increases in the magnitude of hourly precipitation extremes have been documented in the United States (US) over the past half-century ) and climate projections suggest a continued intensification of short-duration precipitation extremes with anthropogenic climate change (Prein et al 2016;Zhang et al 2017).…”

“…Another example is Boulder, Colorado on 12 September 2013, where the absolute record of 1-day precipitation accumulation coincided with a COL. In view of these examples, it is of interest to quantify the contribution of these organized midlatitude systems to hourly precipitation extremes, given the importance of this timescale to storm impacts (Terti et al 2017).…”

Contribution of large-scale midlatitude disturbances to hourly precipitation extremes in the United States

Midlatitude synoptic weather regimes account for a substantial portion of annual precipitation accumulation as well as multiday precipitation extremes across parts of the United States (US). However, little attention has been devoted to understanding how synoptic-scale patterns contribute to hourly precipitation extremes. A majority of 1-h annual maximum precipitation (AMP) across the western US were found to be linked to two coherent midlatitude synoptic patterns: disturbances propagating along the jet stream, and cutoff upper-level lows. The influence of these two patterns on 1-h AMP varies geographically. Over 95% of 1-h AMP along the western coastal US were coincident with progressive midlatitude waves embedded within the jet stream, while over 30% of 1-h AMP across the interior western US were coincident with cutoff lows. Between 30-60% of 1-h AMP were coincident with the jet stream across the Ohio River Valley and southeastern US, whereas a a majority of 1-h AMP over the rest of central and eastern US were not found to be associated with either midlatitude synoptic features. Composite analyses for 1-h AMP days coincident to cutoff lows and jet stream show that an anomalous moisture flux and upper-level dynamics are responsible for initiating instability and setting up an environment conducive to 1-h AMP events. While hourly precipitation extremes are generally thought to be purely convective in nature, this study shows that large-scale dynamics and baroclinic disturbances may also contribute to precipitation extremes on sub-daily timescales.

The last decade has witnessed the development of methodologies for the post‐flood documentation of both hydrogeomorphological and social response to extreme precipitation. These investigations are particularly interesting for the case of flash floods, whose space–time scales make their observations by conventional hydrometeorological monitoring networks particularly challenging. Effective flash flood documentation requires post‐flood survey strategies encompassing accurate radar estimation of rainfall, field and remote‐sensing observations of the geomorphic processes, indirect reconstruction of peak discharges—as well eyewitness interviews. These latter can give valuable information on both flood dynamics and the related individual and collective responses. This study describes methods for post‐flood surveys based on interdisciplinary collaborations between natural and social scientists. These surveys may help to better understand the links between hydrometeorological dynamics and geomorphic processes as well as the relationship between flood dynamics and behavioral response in the context of fast space–time changes of flooding conditions.
