The objective of the study is to develop a GIS-based water infrastructure inventory (WII) for water resources assessment in the upper Srepok basin, Vietnam. The water availability and demand were estimated using common methods. Different water scarcity indicators were estimated to examine the water situation at district level under present and future conditions and future water development needs are assessed. Results reveal that the aggregated information on the basin scale misleads the issue of water situation, especially the scarcity at local level due to high spatio-temporal variations of water resources availability and demands. Most districts in the study basin will experience severe water scarcity in 2010 and 2020 in both physical and economic terms. Generated data from the WII shows very low percentage of water withdrawals in several districts with respect to available resources. Therefore, to meet future demand, significant investment in water infrastructure is needed.
