Abstract

Decreasing availability of in-situ river monitoring datacan be met with increasing availability and quality ofsatellite altimetry data over rivers. CryoSat-2 is analtimeter mission launched in 2010 by the EuropeanSpace Agency (ESA). With its unique drifting orbit,common procedures of working with satellite altimetrydata over rivers cannot be easily applied. This workpresents a way of informing a hydrologic-hydrodynamicmodel of the Brahmaputra River with CryoSat-2altimetry. For one, CryoSat-2 data with its high spatialresolution was used to calibrate water levels in the 1Dhydrodynamic model. For the other, a data assimilationframework was developed and applied, showingpromising results for assimilation experiments with realand synthetic CryoSat-2 data.
