Water Resources in a Changing Climate:
Connections to Ecological and Human Systems
Background and Context
National Research Priorities“Determining how natural fluctuations and anthropogenic
factors impact the water cycle… is a major scientific challenge for the geosciences.”
“Geoscientists must probe more deeply into the coupled, interactive processes of the water cycle”
“quantify variability and alterations in the system(s) caused by global change”
Excerpt from recent NSF program solicitation for Water Cycle Research
Background and Context
(cont.)
“limitations of discipline-based perspectives have become clear”
“integrate across the physical, chemical, biological, and social sciences”
“the challenge… in water resources research… is to engage researchers in novel collaborations”
NRC, 2004. Confronting the Nation’s Water Problems: The Role of Research
Average climate change scenario (ECHAM5).
Temperature difference between the first and last decades of the 21st century for the month of April, the first month of the snow melt season.
Precipitation is expected to be more variable; greater extremes, including prolonged droughts
Projected Climate Change in Idaho
oC
Background and Context
Long-term warming over the past couple of decades is beginning to manifest itself on Idaho’s water resources
• Timing
• Magnitude
(From G. Clarke, USGS)
Background and Context
• Warmer temperatures may increase demand for:– Irrigation and agriculture (evapotranspiration)– Urban areas– Industrial uses (power generation)
And change the timing and magnitude of natural flows, thus affecting:– Natural ecosystems
• Climate change, in general, is expected to change the timing and magnitude of hydrologic systems, which will then impact ecological and human systems.
Research Questions
• How will future climate change impact water resources?
– Hydro - Climate
– Hydro - Economic / Policy
– Hydro - Ecology
Research Questions
• Hydro-climate interactions
– What are the relationships between climate change, vegetation, snow pack, and the resulting stream flows in managed and unmanaged river systems?
– How will aquifer systems exchange with surface and
groundwater under various climate change scenarios?
– What will both the supply and demand on water be in these systems under various climate change scenarios?
Research Questions
• Hydro-Economic / Policy Interactions
– How will changes in the timing and variability of water affect land use, urban growth, and water management within the Snake River Plain?
– How will changes in water availability affect conjunctive use of water and the relative value of surface water and groundwater rights?
– What are the expected changes in ecosystem services related to climate change?
Research Capabilities
• Hydro-Ecological Interactions
– What are the historical relationships among climate, hydrology, geomorphic conditions, fire, and ecology in the Salmon?
– How do current ecological conditions in the Salmon compare with the past?
– Can observed changes in hydrology, geomorphology, disturbances (fire, insects), and ecological health be attributed to changes in climate? If so, can accurate predictions of future changes in ecological conditions be made for the next century?
Building Research Capabilities
• Climate processes in northern Rocky Mountains (regional climate predictions, paleo-climate reconstructions) (Hydro-Climate)
• Coupled modeling of water supply/demand for large-basin water resource planning under a changing climate, including surface/groundwater interactions (large managed basins) (Hydro-Climate, Hydro-Economic/Policy)
• Long-term effects of climate change on natural ecosystems (pristine, unmanaged basins) (Hydro-Ecology)
• Relationship between climate change, changing flow and moisture regimes, and disturbances to the landscape in the northern Rocky Mountains (Hydro-Ecology)
• Development of prospective sites for long-term ecological research [future Long-Term Research in Evolutionary Biology (LTREB) sites,…] (Hydro-Ecology)
Research Plan
• Idaho as a “Natural Laboratory” for climate change research of national significance:
– Snake River Plain (SRP) • Large, Managed Hydrologic Systems
– Salmon River Basin (SRB) • Pristine, relatively unmanaged Hydrologic Systems

Leveraging
• External Mentors– Overall Team Management
• Ed Miles (CIG, U. Washington)
– Hydro-climatology• Dennis Lettenmaier (U. Washington)
– Hydro-Ecological Interactions• Steve Running (U. Montana)
– Hydro-Economic• John Antle (Montana State Univ.)
Leveraging
• Organizational Strategy
– Complement establish research activities at the Climate Impacts Group (CIG) at U. Washington
– CIG as an “Mentor Organization”
Leveraging
• Collaboration with neighboring EPSCoR programs– Idaho, New Mexico, and Nevada are all focusing on
Climate Change in this RII.
– Idaho’s efforts are complementary to other states.• New Mexico - Climate Change and Mountain Hydrology• Nevada - Climate Change in desert regions; soil processes
– NSF has “strongly encouraged” these 3 states to work together, especially on cyberinfrastructure.
Leveraging
• Field Sites– Snake River Plain
• Long-term commitment to modeling of surface and groundwater
– Salmon River Basin• Long-term datasets on riparian systems (of many orders)
originally related to fire research
– INL plant community plots• Long-term data records of changes in plant species distributions
and their relationship to hydrologic processes
– Reynolds Creek Experimental Watershed• Existing infrastructure for process studies on snowmelt.• Long-term data records for hydrologic, BGC, and invasive species
modeling.
