River channel connectivity shifts metabolite composition and dissolved organic matter chemistry

Publications Posted on: July 29, 2020
Biogeochemical processing of dissolved organic matter (DOM) in headwater rivers regulates aquatic food web dynamics, water quality, and carbon storage. Although headwater rivers are critical sources of energy to downstream ecosystems, underlying mechanisms structuring DOM composition and reactivity are not well quantified.

Watershed management contributions to land stewardship: A literature review

Publications Posted on: June 22, 2020
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.

New gaging station for mountain streams: Forest Service installation combines a San Dimas flume with two broad-crested weirs

Publications Posted on: February 19, 2020
One of the many duties of the Forest Service of the U.S. Department of Agriculture is the investigation of watershed management. A phase of this subject is the measurement of the flow of mountain streams, which varies through a wide range.

Methods for the measurement of infiltration

Publications Posted on: February 19, 2020
The measurement of infiltration has, in recent years, assumed increasing importance as a means of estimating the relative absorptive capacities of soils under different vegetal types or kinds of land use. The utility of infiltration-criteria rests partly on the assumption that surface-runoff in any appreciable volume is deleterious and that it results in movement of soil and in excessive peak-rates of stream-flow.

Some relationships of plant cover to run-off, erosion, and infiltration on granitic soils

Publications Posted on: February 19, 2020
The fact that plant cover influences run-off, erosion, and infiltration has been firmly established by past research. Only under a few special conditions, however, has the degree of this influence been determined quantitatively. The study reported in this article was undertaken to secure a usable measure of this quantitative relationship, and to provide data for watershed management in the mountains of Colorado.

Notes from the Manitou Experimental Forest

Publications Posted on: February 19, 2020
The Manitou Experimental Forest is a branch of the Rocky Mountain Forest and Range Experiment Station. It is in the Pike National Forest, 28 miles north and west of Colorado Springs. This experimental area of 26 square miles was established in 1936 to study problems of watershed management, grazing, and other kinds of land use in the Front Range of the Colorado Rockies.

Watershed management experiments in the Colorado Front Range

Publications Posted on: February 12, 2020
Summer cloudburst storms occur frequently on the eastern flank of the Colorado Range below 9,000 feet elevation. The intensity of these storms is high, often exceeding three inches per hour for 10-minute intervals. Floods from the cloudburst storms cause much damage to lands and improvements in the adjacent plains.

Managing vegetation to increase flow in the Colorado River Basin

Publications Posted on: July 31, 2019
Water yield from forest and rangelands can be augmented by managing vegetation and snow to reduce evapotranspiration. Some arbitrary goals to increase water yield were chosen to illustrate the potential for increasing water yield, and treatments were hypothesized to get these increases.

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.

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.
