Dwindling water resources, increasing susceptibility to hydrologic, hydrometeorological and hydroclimatological extremes, and climate change and variability demand more accurate and reliable water information and put increasingly higher premium on actionable predictive water information. HWRL focuses on integrative hydrologic prediction and water resources information research for sustainable and resilient management and planning of water resources and hazards.
