SO, OUR PROJECT GOALS
• To improve our understanding of how large-scale human activities (dam infrastructure and associated irrigation) cumulatively affect ecological processes in wetland ecosystems, and to provide a scientific basis for the improved operation of such infrastructure to help mitigate the expected effects of climate change.

DAMS IN THE MEKONGPokhrel et al. (2018)
Pokhrel et al. 2012, 2015
• Existing dams do not have significant impact on the flow in the mainstream
• Impacts on tributaries could be significant• Future dams are likely to largely affect the
mainstream flow

• Developed, calibrated and tested an ensemble modeling approach to quantitatively link human activities (dams, irrigation and water withdraw etc.) to hydrological processes.
Figures: Comparison of modeled and observed flow rates and inundation.

• Used MODIS and Landsat time series to detect construction and operation dates, information that has implications to water resources in the basin.
