A cloud-based system will be developed to deploy urban water analytics that are developed by UWIN projects and pareRAMS-leaf-logo-FINAL-for-webtners.  The system is designed using the environmental Resource Assessment and Management System (eRAMS) and is called Urban-Water Resources Assessment Program (Urban-WRAP).  The system provides computationally scalable, accessible and platform independent web services for the assessment of the UWIN urban water sustainability indicators in regions across the U.S.  A governing rule for the development of the decision innovation system is that complexity is analyzed comprehensively, but decision information is presented to communities and regulators in understandable forms to support informed choices

Dr. Mazdak Arabi is the Borland Endowment Professor of Water Resources in the Civil and Environmental Engineering Department at CSU. He serves as the Director of CSU’s One Water Solutions Institute.  His research, educational, and engagement activities are primarily focused on the development of decision support systems for sustainable management of water resources. Dr. Arabi has developed novel system identification and optimization approaches to facilitate development of solutions for reliable and resilient regional water systems. He is the principal inventor of the environmental Resources Assessment and Management System (eRAMS), a cloud-computing technology for integration of location-based information with simulation models of water, food, and energy systems. The eRAMS platform currently supports more than 200 analytics and decision tools that have been developed in collaboration with other research institutions as well as federal, state and local government agencies.  Dr. Arabi also serves as the Director of several major research programs, including the National Science Foundation’s Urban Water Innovation Network, the Environmental Protection Agency’s Center for Comprehensive, optimal and Effective Abatement of Nutrients (CLEAN Center), and the Water Sustainability & Climate Center.
