COMPARISON OF MODEL OUTPUTS WITH ESTIMATED PARAMETERS FROM REMOTE SENSING FOR THE OB RIVER IN SIBERIA

The Ob river is one of the largest rivers in the Arctic and variations in the hydrological cycle due to climate changes might have far reaching global consequences. This work aims at modelling the Ob river basin and comparing model outputs to remotely sensed observations of water level. The models used are the land surface scheme ISBA developed by the CNRM, France, which has been coupled to the flood inundation model LISFLOOD-FP developed by the University of Bristol, UK. Water levels obtained from satellite altimetry and from in-situ data are compared to the modelled water elevations. We also intend to use a relatively simple “end to end” simulator first developed for ocean studies and adapted here for the simulation of the Ob river basin. Based on a simplified version of the recently published Ensemble Twin Experiments methodology (Mourre et al., 2004), the simulator aims at quantifying the potential of the wide swath altimeter onboard the future WATER-HM (Water And Terrestrial Elevation Recovery Hydrosphere Mapper) satellite mission by estimating its ability to reduce the statistical error of the ISBA/LISFLOOD-FP model.
