Supporting energy and mineral development through successful reclamation
Southwest Biological Science Center
The SBSC provides sound science, specialized expertise, and objective and timely tools to Federal and State agencies and the public to inform land management decision-making, and support thriving landscapes for the Southwest’s abundant natural resources and vast public lands. This research assists those who manage, conserve, and rehabilitate rivers and arid regions of the nation.
Dryland Ecology and Management Support: our Terrestrial Drylands Ecology branch
Dryland Ecology and Management Support: our Terrestrial Drylands Ecology branch
SBSC conducts research in terrestrial drylands to deliver information that aids land & wildlife management to promote productive ecosystems. Our work provides tools used to mitigate impacts of drought, wildfire, and invasive species, as well as science that supports Department of the Interior economic and cultural activities including recreation and ranching.
Grand Canyon Monitoring and Research Center & Lake Powell research: our River Ecosystems branch
Grand Canyon Monitoring and Research Center & Lake Powell research: our River Ecosystems branch
The SBSC Rivers branch, which includes the Grand Canyon Monitoring & Research Center, studies the biology, ecology, and processes of rivers, primarily in the SW. We provide the public and decision makers with relevant scientific information about the status and trends of natural, cultural, and recreational resources of the Colorado River in Grand Canyon, and Lake Powell.

Fluvially-sourced sediment supply and climate modulate morphodynamics and state transitions in bistable aeolian dunefields Fluvially-sourced sediment supply and climate modulate morphodynamics and state transitions in bistable aeolian dunefields
Alternative stable state theory in aeolian geomorphology describes the occurrence of bare and vegetated aeolian dunes in response to long-term climatic and ecological drivers. Transitions between states, as well as their co-occurrence (bistability), can arise from perturbations to drivers, disturbance, and associated biophysical feedbacks. Here, we examine the role of upwind fluvial...
Human factors used to estimate and forecast water supply and demand in the Delaware River Basin Human factors used to estimate and forecast water supply and demand in the Delaware River Basin
The objective of this report by the U.S. Geological Survey is to identify cultural and economic determinants of water demand, supply, and access, and to locate associated datasets of those determinants. Although climate and its influence on hydrology are important components of water availability, this study focused only on the components of the human system. The Delaware River Basin...
First application of a coastal-dune model (AeoLiS) to simulate fluvial-aeolian morphodynamics First application of a coastal-dune model (AeoLiS) to simulate fluvial-aeolian morphodynamics
Quantifying aeolian processes is important to decision-making in river management and for optimizing strategies for ecosystem conservation, natural resource management, and recreation. We applied the AeoLiS aeolian transport model, originally developed for coastal environments, to a dryland river corridor to evaluate its ability to simulate sediment dynamics in a fluvial-aeolian system...

Holding the Ground: Long-Term Science and Partnerships Help Protect Soil Health and Local Economies Across the Colorado Plateau
By combining long-term science with enduring partnerships, USGS is helping decision makers protect soil resources, reduce erosion risks, and steward America's public lands for future generations.
Copper mining, critical minerals, and long-term drought in the Southwest United States
Long-term drought in the Southwest U.S. affects water use across many sectors as well as the natural environment. The Southwest U.S. is an important area for mining porphyry copper deposits, which consist of copper minerals disseminated in breccia, a type of rock composed of coarse rock fragments held together by cement or a fine-grained matrix, that are the World's largest source of copper...
Enhancing Rangeland Recovery by Forecasting Seed Establishment
This project is synthesizing information about plant establishment and building a tool to deliver forecasts of restoration success, helping to maximize the chances that restoration efforts will be successful.
