Soils and water

Publications Posted on: October 28, 2021
Wildlands play a special role in providing a reliable supply of high-quality water (Dissmeyer 2000), and, in particular, we rely on forest and rangeland soils to ensure clean, abundant water. Soils retain water and make it available to support vegetation, facilitate drainage to soil and ultimately to surface waters (streams and lakes), and recharge aquifers and groundwater.

The future hydrology of the Colorado River Basin

Publications Posted on: September 27, 2021
Long-range planning of the water supply provided by the Colorado River requires realistic assessments of the impact of a continuation of the current drought that began in 2000, the impact of potentially extreme future droughts, and the long-term and progressive decline in watershed runoff that is caused by a warming climate.

Modeling forest management effects on water and sediment yield from nested, paired watersheds in the interior Pacific Northwest, USA using WEPP

Publications Posted on: September 25, 2021
The Water Erosion Prediction Project (WEPP) model was applied to seven paired, nested watersheds within the Mica Creek Experimental Watershed located in northern Idaho, USA. The goal was to evaluate the ability of WEPP to simulate the direct and cumulative effects of clear-cutting and partial-cutting (50% canopy removal) on water and sediment yield.

Implications of climate variability and changing seasonal hydrology for subarctic riverbank erosion

Publications Posted on: June 23, 2021
Warmer climatic conditions have been associated with numerous hydrologic changes that may impact riverbank erosion in cold regions, but the net effect is not well understood. We used regression and correlation analyses to examine the relationships among subarctic riverbank erosion and seasonal hydrology, the impact of climate change and variability, and the societal implications.

Geospatial data for Great Basin perennial montane watersheds - geomorphology, hydrology, vegetation, disturbance and species

Datasets Posted on: December 30, 2020
Multiple partners working together developed a multiscale approach for assessing the geomorphic sensitivity of streams and ecological resilience of riparian ecosystems, including meadows, in upland watersheds of the Great Basin to disturbances and management actions. This data publication contains the geospatial data, representative of 2020, resulting from that work.

Characterizing ecoregions and montane perennial watersheds of the Great Basin

Publications Posted on: November 18, 2020
Multiple research and management partners collaboratively developed a multiscale approach for assessing the geomorphic sensitivity of streams and ecological resilience of riparian and meadow ecosystems in upland watersheds of the Great Basin to disturbances and management actions. The approach builds on long-term work by the partners on the responses of these systems to disturbances and management actions.

Intended versus unintended effects during riparian restoration create high quality recreation habitat [Chapter 10]

Publications Posted on: July 17, 2020
Many of the same features that are good for riparian ecology are good for people. Varying flow regimes, diversity of plants and animals, dynamic geomorphology that produces open beaches and shaded/sheltered areas, and most importantly, the presence of water - all are attractive for recreation, so human use can be an explicit part of the restoration equation.

Recreation habitat versus ecological habitat in riparian areas: Can we manage for both? [Chapter 9]

Publications Posted on: July 17, 2020
Yosemite Valley is a narrow, steep-walled canyon with fantastic natural areas, and its scenic and ecological wonders inspired the National Park concept and preservation ethic. But the Merced River through Yosemite Valley is one of the most heavily used non-urban riparian areas in the world. Over 4 million people visit each year, and 90 percent go to the box canyon where towering granite summits rise over 4,000 feet above the meandering river.

Sacramento-San Joaquin System [Chapter 8]

Publications Posted on: July 17, 2020
The Great Central Valley of California occupies 22,500 square miles (58,000 square kilometers) in the interior of northern and central California. At the time of the Gold Rush in 1849, nearly 1 million acres (1,600 square miles, 4,000 square kilometers) of riparian vegetation covered the Central Valley floor along with approximately an equal area of wetlands.

The development of riparian ecosystem restoration in California [Chapter 7]

Publications Posted on: July 17, 2020
The evolution of our modern-day understanding of riparian ecology and the development of the field of riparian ecosystem/habitat restoration underwent significant advances from 1970 to 2000.
