The Influence of Land Use Projection Uncertainty on Flow and Sediment Estimations: A Case Study from the Mekong Basin

摘要

Quantitative understanding of potential changes of flow and sediment is complicated by uncertainty related to land use change projections. Without accessing uncertainty, it can be difficult for policymakers and resource managers to develop effective land use policies and management programs. This study aims to investigate the implication of uncertainty in land use change projections on flow and sediment estimations using the Soil and Water Assessment Tool (SWAT) model. We applied SWAT to the Sesan, Srepok, and Sekong Rivers (3S) (Figure 1) in the Mekong (the most important tributaries of the lower Mekong containing valuable protected areas) as our test basin, but lessons learned from this research can be useful globally.
