Evaluating the impacts of climate change on the hydrologyand water resource availability in the 3S river basin of Cambodia, Laos, and Vietnam

Abstract

As emphasised in the IPCC Fifth Assessment Report (AR5), climate change is occurring across nearly all the regions of the world [1]. Climate change can considerably affect the regional hydrology and water resources through changes in hydrological processes, especially in evapotranspiration, soil water, and surface runoff. Furthermore, climate change may include an increased frequency and magnitude of hydro-meteorological extremes, namely droughts and floods [2]. Such hydrological changes will lead to the redistribution of water resources that impact water supply, hydropower, and irrigation on multiple scales. Therefore, discovering ways that water resource systems can be impacted and their respond to climate change scenarios has been the research topic of interest of the IPCC and many other international organizations and research institutions.
