Overview

This section of the Wiki highlights new (2020- ) research publications relevant to the management of water and related resources in the Colorado River Basin: peer-reviewed papers, book chapters, agency reports, and other documents.

Below, these publications are listed by year of publication and organized by topic. Some publications are listed under more than one topic. A stable link to the online publication is provided at the end of each listing; for journal articles, the link goes to the article's homepage at the publisher's website.

A note on paywalls: While open access research has become much more prevalent in recent years, many of the journal articles listed below sit behind paywalls. If you don't have personal or institutional access to that journal/article, you will only be able to view the abstract; viewing or downloading the full text requires a payment (typically exorbitant). If that happens, first, enter the title of the article in Google Scholar and check if a PDF has been posted elsewhere on the web by an author or other person. If one hasn't been posted, then look at the top of the article's homepage for the corresponding author (not always the first author), and email that person to obtain a copy.

Selected publications whose titles are bold links below have a dedicated page on this Wiki.

Wiki library

All of the new (2020- ) publications listed below, plus another 400+ earlier publications that were used as references for the 2020 CRB State of the Science report, can also be viewed in this searchable online database (a Zotero library).

The library allows users to view the bibliographic information like shown below, plus the abstract for many publications, and to search by author, year, or keyword. Links are provided to the vast majority of these publications; for journal articles, the link goes to the article's homepage at the publisher's website, where users may encounter a paywall.
