Abstract: Mekong River is the most important trans-boundary river in Southeast Asia, with a length of almost 4,900 km, a total catchment area of 795,000 km2 and an average discharge of 14,500 m3/s. Currently, the Mekong River Basin (MRB) is experiencing rapid economic development, urbanization and population growth. Moreover, a changing global climate will place additional pressure on the MRB. Consequently, water-related problems such as water disaster and water pollution are worsening in the basin and it make the water management in MRB challenging. In order to simulate the eco-hydrological processes in the MRB, we built a distributed GeomorphologyBased Hydrological Model of the Mekong River (GBHM-MK) using remote sensing data and other publicly available data, to overcome the problems caused by the poor data quality and/or limited gauge availability. The accuracy of GBHM-MK was verified by comparing simulated discharges to the gauge observation. The components of the eco-hydrological process were analyzed over the MRB. This paper will give details about the model development and some of the challenges in applying remote sensing data in the Mekong River System.
