Winds blowing trees with a grey sky and a truck tring to drive through flooding

Researchers at The University of Alabama are working to develop advanced computational earth science and coastal models that help coastal communities prepare for flooding from tropical storms and hurricanes.

Thank you for visiting the CCHR website. CCHR was founded in 2018 to foster collaborative research and build global capacity for the grand challenges in the twenty-first century on water security faced by water resources planners and natural disasters dealt by emergency managers. We conduct cutting-edge research at the intersection of Climate, Water, Energy, Food and Human as a complex system with the goal of meeting societal demands and also protecting the livelihood against natural disasters as populations swell and weather patterns shift in varying climate. In response to variations and changes in the physical environment, including climate, land use, land cover, topography, etc., we harness data revolution from variety of resources including in-situ, reanalysis, tree ring and remotely sensed observations, and develop/apply state-of-the art computational modeling with emphasis on predictive science, machine learning, data assimilation, high-performance computing, agent-based modeling and cyber-evolution to quantify, reduce and communicate uncertainty, vulnerability and risk in our analysis and design to assist local, federal and international agencies and stakeholders, meeting their needs.

CCHR is housed in the College of Engineering with over 50 faculty members, postdocs and students with expertise across 3 colleges and 7 departments including, Civil and Environmental Engineering, Computer Science, Mathematics, Geography, Geological Sciences, Biological Sciences, and Public Relations.
