River rafting trips and hikers use sandbars along the Colorado River in Marble and Grand Canyons as campsites. The U.S. Geological Survey evaluated the effects of Glen Canyon Dam operations on campsite areas on sandbars along the Colorado River in Grand Canyon National Park. Campsite area was measured annually from 1998 to 2012 at 37 study sites between Lees Ferry and Diamond Creek, Arizona. The primary purpose of this report is to present the methods and results of the project.

Campsite area surveys were conducted using total station survey methods to outline the perimeter of camping area at each study site. Campsite area is defined as any region of smooth substrate (most commonly sand) with no more than an 8 degree slope and little or no vegetation. We used this definition, but relaxed the slope criteria to include steeper areas near boat mooring locations where campers typically establish their kitchens.

The results show that campsite area decreased over the course of the study period, but at a rate that varied by elevation zone and by survey period. Time-series plots show that from 1998 to 2012, high stage-elevation (greater than the 25,000 ft3/s stage-elevation) campsite area decreased significantly, although there was no significant trend in low stage-elevation (15,000–20,000 ft3/s) campsite area. High stage-elevation campsite area increased after the 2004 and 2008 high flows, but decreased in the intervals between high flows. Although no overall trend was detected for low stage-elevation campsite areas, they did increase after high-volume dam releases equal to or greater than about 20,000 ft3/s. We conclude that dam operations have not met the management objectives of the Glen Canyon Adaptive Management program to increase the size of camping beaches in critical and non-critical reaches of the Colorado River between Glen Canyon Dam and Lake Mead.

Biography: 

Paul Grams has worked directly with the Glen Canyon Dam Adaptive Management Program (GCDAMP) since 2008, as a program manager and research hydrologist at the Grand Canyon Monitoring and Research Center (GCMRC). His involvement in Grand Canyon studies goes back to 1991, when he took a Colorado River research trip as part of an undergraduate science course. Grams is an expert on the effects of dams on river geomorphology and sediment transport. He holds a BA in Geology from Middlebury College, an MS in Geology from Utah State University, and a PhD in Geography and Environmental Engineering from Johns Hopkins University.

Materials produced for the workshop hosted by the Humane Cities Initiative, Institute for Humanities Research, Arizona State University. Participants were sent this package of archival materials and links to brief online sources for advance readings. Also enclosed are PDF renderings of introductory powerpoint files by Spindler and Pagan, and an audio recording of the discussion joined in progress.

Presentation slides regarding the history of Victory Village, the trailer park built in 1945-46 to provide housing for WWII Veterans and their families at Arizona State University's Tempe campus. A presentation of research from University Archives records conducted in the summer of 2018. The presentation was videotaped as a lecture for Professor Volker Benkert's online World War II history class.

This research study will discover and evaluate information about existing crowdsourcing or participatory archives projects devoted to archival description, indexing or transcription. Many related projects that use crowdsourcing for collecting archival materials from the public are not specifically addressed here. In this research, the author has specifically sought evaluative information about exemplary projects that can lead to useful specifications for a participatory archives system at Arizona State University Libraries.

The Task Force of thirty faculty members and academic professionals was charged by the University Libraries and the Graduate College to "examine the potential for implementing a university program for Electronic Theses and Dissertations (ETDs). The Task Force was specifically asked to collect information about existing programs elsewhere, identify ASU graduate programs that could host pilot programs and prepare a comprehensive white paper..." with a recommended plan for implementation.
