Quantifying the extent of drought and flood magnitude and frequency under the climate change impacts is essential for an effective water resource management. In this study, we utilize the Soil and Water Assessment Tool (SWAT) hydrological model, drought indices as well as the Interquartile Range (IQR) method for a comprehensive analysis of the river flow response to projected climate change scenarios. Four General Circulation Models (GCMs) under two Shared Socioeconomic Pathways (SSP2-4.5 and 5-8.5) have been used for our analysis (2023-2090). Our objective is to reveal the future projected drought and flood events in terms of intensity, frequency, and potential consequences for local livelihoods in the Srepok River basin (SRB), a tributary of the Mekong River basin (MRB), Southeast Asia. Our findings serve as the scientific basis for stakeholders and decisionmakers to develop adaptative strategies and sustainable plans to promote the region's resilience.

This contribution highlights part of training events designed to collect, analyze, and manage water and water-related data (e.g., climate, weather, land, soils) and information products for the purposes of reducing water-related risks, and improving regional responses to environmental emergencies in the Mekong region. In this work, we discuss multiple tools and applications developed by National Aeronautics and Space Administration (NASA) scientists to lower technical barriers through current web technologies and leveraging data sharing capabilities among existing programs and institutions within different parts of the Mekong region. The aim of this training contribution is to leverage a well-established suite of tools that include but are not limited to remote sensing precipitation data adjustment techniques, i.e., the SWATOnline visualization and modeling system, and the NASAaccess data toolkit. The collaborative training events, which this contribution is part of, are administered by the United States Department of State (DOS) and the Ministry of Foreign Affairs - Republic of Korea under the Mekong-US Partnership and its Mekong Water Data Initiative facilitated by Sustainable Infrastructure Partnership (SIP) program. The Mekong Water Data is a DOS Initiative consists of multiple efforts and programs with an overarching objective of building the capacity of Mekong riparian countries and the Mekong River Commission Secretariat (MRCS), National Mekong Committees and line agencies in the Lower Mekong countries to improve the management of the Mekong River.
