Hazard assessment for river flooding using river discharge statistics#
This workflow uses the dataset of hydrological climate impact indicators by SMHI that is available via the Copernicus Data Store.
The following variables are used in this workflow:
daily timeseries of gridded river discharges in the historical period based on the E-HYPEgrid model.
monthly means of gridded river discharges over a 30-year period (1971-2000) based on the E-HYPEgrid model.
monthly means of catchment-level river discharges (in the period 1971-2000) based on the E-HYPEcatch multi-model ensemble.
extreme river discharges in the historical climate (1971-2000) based on the E-HYPEcatch multi-model ensemble.
relative change in extreme river discharges in early-, mid- and end-century under climate scenarios based on the E-HYPEcatch multi-model ensemble.
The resolution of the gridded dataset is 5km. The resolution of the catchment-level data is approx. 0.11 degrees (5-10 km).
Relative change in flood recurrence data is available for 2, 5, 10, 50-year return periods and for the following timelines:
early century (2011-2040)
mid-century (2041-2070)
end-century (2071-2100)
For each time period, climate scenarios RCP2.6, RCP4.5 and RCP8.5 are available.
Relative increases in flood recurrence for these periods are expressed relative to the reference period (1971-2000).
