FLOODRisk 2016, 3rd european conference on flood risk management, LYON, FRANCE, 17-/10/2016 - 21/10/2016The influence of rainfall spatial variability on hydrographs modelling at catchment outlet remains an open scientific  debate. Emmanuel et al. (2015) have  proposed  rainfall variability  indexes  aiming  at  summarising  the influence  of  rainfall  spatial  organisation  on  hydrographs features.  This  preliminary  work  was  based  on  a large  simulated  database.  The  present  article shows how the proposed indexes may be used in a real case study to discriminate rainfall events for which information on spatial  rainfall  organization  is  crucial  for  hydrograph modelling,  and  therefore  to  better  illustrate  the added  value  of  high resolution rainfall information as input of hydrological models. The presented case study is located in the Cevennes Region in  south-eastern  France.  The  tested  flow  events  are  split  into  two subsets  according  to  the  values  of  the  rainfall variability indexes.  The  comparison  between  modelled and  measured  hydrographs  is  then  performed separately  for  each  subset.  The results obtained suggest that, on average, modelling results taking into account high resolution rainfall data are significantly improved for the subset for which the influence of rainfall variability is expected to be significant according to the indexes values. Although limited to a relatively small number of hydrographs, this case study can be viewed as a first confirmation of the pertinence of the rainfall variability indexes proposed in Emmanuel et al. (2015) to investigate the influence of rainfall spatial variability on the shape of hydrographs at catchment outlet
