DISTRIBUTED MODELLING APPROACHES FOR BASIN SCALE SEDIMENT DYNAMICS AND THEIR APPLICATION TO MEKONG RIVER BASIN

Modelling of soil erosion and sediment dynamics has been regarded as a challenging task as they are highly dynamic processes including erosion, transport and deposition. Recently, such modelling work attracts more attention, yet only a few have been reported for large river basins (e.g., drainage area > 100 000 km2). In this study, therefore, distributed models for assessment of sediment dynamics at large basin scale were developed. The models have been then tested on a large river basin in Southeast Asia, Mekong River Basin (795,000 km2). Additionally, several scenarios analyses were conducted considering climate change and planned dams to assess those impacts on sediment dynamics in the basin. Overall, the results indicated that the developed models can be used to seek the appropriate management practices in terms of erosion and sediment transport in large river basins.
