History of watershed research in the Central Arizona Highlands

Publications Posted on: August 01, 2018
The Central Arizona Highlands have been the focus of a wide range of research efforts designed to learn more about the effects of natural and human induced disturbances on the functioning, processes, and components of the region's ecosystems.

Watershed management contributions to land stewardship: A literature review

Publications Posted on: August 01, 2018
An international conference to increase people's awareness of the contributions that watershed management can make to future land stewardship was held in Tucson, Arizona, March 13-16, 2000. This bibliography is a compilation of the synthesis and poster papers presented at the conference along with the literature cited in these papers on watershed research projects, applied watershed management activities, and technology transfer mechanisms.

Development of online tools to support GIS watershed analyses

Publications Posted on: January 06, 2017
In 1996 there was a meeting in Tucson of hydrologists from every Forest Service region, as well as Forest Service research scientists engaged in watershed-related activities. This meeting was organized by the Stream Team (which has since been enveloped by the National Stream and Aquatic Ecology Center). The focus of the meeting was to identify tools that needed to be developed to support watershed management.

Land Stewardship in the 21st Century: The Contributions of Watershed Management; 2000 March 13-16; Tucson, AZ

Publications Posted on: May 12, 2016
The purpose of this conference was to increase awareness through exploration and evaluation of global, national, and regional perspectives about the potential contributions that watershed management can make to the conservation, sustainable development, and use of natural resources in ecosystem-based land stewardship in the 21st century. The conference consisted of 2 and a half days of synthesis papers.

The case for regime-based water quality standards

Publications Posted on: May 12, 2016
Conventional water quality standards have been successful in reducing the concentration of toxic substances in US waters. However, conventional standards are based on simple thresholds and are therefore poorly structured to address human-caused imbalances in dynamic, natural water quality parameters, such as nutrients, sediment, and temperature.

Sierra Ancha Experimental Forest

Experimental Forests and Ranges Posted on: September 09, 2015
The U.S. Forest Service established the Sierra Ancha Experimental Forest in 1932 as a research area for studying watershed management. Located within the Tonto National Forest, the climate, soil, and landforms of the Sierra Ancha are representative of much of the southwestern region of the United States.

Clearcutting and burning slash alter quality of stream water in northern Idaho

Publications Posted on: August 17, 2015
In the cedar-hemlock-grand fir ecosystem clearcutting of units of varying size (2.6 to 44 ha) and subsequent disposal of slash by prescribed burning resulted in on-site stream water quality changes. But off-site changes were of less intensity. Two of three clearcut units responded in this manner; a third unit gave different results.

Hydrologic calibration and validation of SWAT in a snow-dominated Rocky Mountain watershed, Montana, USA

Publications Posted on: July 28, 2015
The Soil and Water Assessment Tool (SWAT) has been applied successfully in temperate environments but little is known about its performance in the snow-dominated, forested, mountainous watersheds that provide much of the water supply in western North America. To address this knowledge gap, we configured SWAT to simulate the streamflow of Tenderfoot Creek (TCSWAT).

The Black Hills (South Dakota) flood of June 1972: Impacts and implications

Publications Posted on: May 07, 2015
Rains of 12 inches or more in 6 hours fell on the east slopes of the Black Hills the night of June 9, 1972. Resulting flash floods exacted a disastrous toll in human life and property. Rainfall and discharge so greatly exceeded previous records that recurrence intervals have been presented in terms of multiples of the estimated 50- or 100- year event. Quick runoff was produced in the heaviest rainfall areas regardless of hydrologic condition.

Isotope hydrology and baseflow geochemistry in natural and human-altered watersheds in the Inland Pacific Northwest, USA

Publications Posted on: March 17, 2015
This study presents a stable isotope hydrology and geochemical analysis in the inland Pacific Northwest (PNW) of the USA. Isotope ratios were used to estimate mean transit times (MTTs) in natural and human-altered watersheds using the FLOWPC program. Isotope ratios in precipitation resulted in a regional meteoric water line of ä2H = 7.42·ä18O + 0.88 (n = 316; r2 = 0.97).
