New research: Difference between revisions

Revision as of 16:45, 9 June 2021

This section of the wiki highlights new research publications--peer-reviewed papers, book chapters, agency reports, and other documents--relevant to the management of water and related resources in the Colorado River Basin.

Below, the bibliographic information for those publications is organized chronologically, and then by the main topic. A link to the online publication is provided at the end of each listing, annotated with a ($) if the publication is behind a paywall. To obtain a copy of any publication behind a paywall, contact Jeff Lukas: jeff AT lukasclimate DOT com

Selected publications that are noteworthy and/or especially useful to basin stakeholders--whose titles are bold links below--have a dedicated Wiki page, including a plain-language summary of 500 words or less.
