  abstract = {{F}lash-floods are among the most devastating hazards in the {M}editerranean. {A} major subset of damage and casualties caused by flooding is related to road submersion. {D}istributed hydrological nowcasting can be used for road flooding monitoring. {T}his requires rainfall-runoff simulations at a high space and time resolution. {D}istributed hydrological models, such as the {ISBA}-{TOP} coupled system used in this study, are designed to simulate discharges for any cross-section of a river but they are generally calibrated for certain outlets and give deteriorated results for the sub-catchment outlets. {T}he paper first analyses {ISBA}-{TOP} discharge simulations in the {F}rench {M}editerranean region for target points different from the outlets used for calibration. {T}he sensitivity of the model to its governing factors is examined to highlight the validity of results obtained for ungauged river sections compared with those obtained for the main gauged outlets. {T}he use of improved model inputs is found beneficial for sub-catchments simulation. {T}he calibration procedure however provides the parameters' values for the main outlets only and these choices influence the simulations for ungauged catchments or sub-catchments. {A}s a result, a new version of {ISBA}-{TOP} system without any parameter to calibrate is used to produce diagnostics relevant for quantifying the risk of road submersion. {A} first diagnostic is the simulated runoff spatial distribution, it provides a useful information about areas with a high risk of submersion. {T}hen an indicator of the flood severity is given by simulated discharges presented with respect to return periods. {T}he latter has to be used together with information about the vulnerability of road-river cross-sections.},
