| This study aims to predict the formation and migration of sandbars in alluvial Brahmaputra River by means of numerical simulations and satellite information in order to obtain useful information for river management. Numerical simulation, which is conducted by Takebayashi et al.’s model, requires an initial conditions for channel geometry which is usually specified by field surveyed data. However the surveyed data are very limited and in addition, the river planform changes continuously. Therefore satellite information from the Panchromatic Remote-sensing Instrument for Stereo Mapping Digital Surface Model (PRISM-DSM) of Japan Aerospace Exploration Agency (JAXA) are used for defining the initial channel planform. |
