Compounding Impacts of Human-Induced Water Stress and Climate Change on Water Availability

Abstract The terrestrial phase of the water cycle can be seriously impacted by water management and human water use behavior (e.g., reservoir operation, and irrigation withdrawals). Here we outline a method for assessing water availability in a changing climate, while explicitly considering anthropo...
