The Universities Council on Water Resources is a multi-disciplinary association of primarily North American universities dedicated to the advancement of research, education and service in water resources. Its principle publication, the Journal of Contemporary Water Research and Education (formerly Water Resources Update), is a peer-reviewed journal published both on paper and in electronic form on Wiley-Blackwell’s Synergy website (www.blackwellsynergy.com) where they can be downloaded by researchers, educators, and policy-makers around the world. JCWRE identifies topics for special issues and the issue editor invites authors to write on those topics. At-large submissions on these topics submitted by the deadline of a specific issue will also be reviewed. Articles published in JCWRE are widely recognized for their concise clarity and relevance to critical water resources issues and principles.
