Presentation Transcript

  1. EPSCoR Water Dynamics WorkshopHighlights from the Northeast and Appalachian States Michelle Daley Research Scientist, University of New Hampshire Associate Director, NH Water Resources Research Center

  2. 2000 to 2030 Urbanization/Suburbanization and Climate Change Timing of Spring Runoff in Maine Percent Change in Total Population 2000 to 2030 by Northern New England County USGS Fact Sheet FS 2005-3001

  3. Urbanization/Suburbanization and Water Quantity • New England is a water rich area and yet we still face issues with water supply • In stream flow rules to protect aquatic and terrestrial biota and human use Example Issues…. • Local cross basin transfers • Global cross basin transfers – water bottling plants • Unregulated private well withdrawals • Artificial aquifer recharge

  4. Urbanization/Suburbanization and Water Quality:Road Salt Impacts on Stream Salinization Chronic Toxicity Southeast NH Central NH Photo Credit: New Hampshire Department of Transportation Data from NH WRRC

  5. Suburbanization and Water Quality:Coastal Nitrogen Flux Driven by Population Density Sub-basins of the Lamprey River Hydrologic Observatory

  6. What controls long-term N Balance? Nitrogen Inputs and Outputs from the LRHO (2005) Total N Input 15.4 kg N ha-1 yr-1 Total N Retention 84% (or 13.0 kg N ha-1 yr-1)Stored or lost to atmosphere? Food 3.1 Fertilizer 1.8 Rain and dry deposition 10.5 Total N Output 2.4 kg N ha-1 yr-1 0.82 kg DIN ha-1 yr-1 (5 % of N Inputs)

  9. Suburban Stormwater Management in Vermont How sensitive are streams to stormwater stressors? Are streams that are structurally impaired also functionally impaired? How can scientific knowledge be used to manage stormwater discharge to Vermont’s streams? How long will it take for streams recover from stormwater impairment? Research questions courtesy of Breck Bowden, UVM

  10. ? ? Climate Change

  11. Future Challenges in the Northeast • Impacts of climate change layered with suburbanization • Arsenic (interactions with other constituents) • Pharmaceuticals and Personal Care Products (PPCPs) • Groundwater water rights • Better interactions with society and policy makers

  12. Challenges for the Appalachian States –WV, KY, TN • Large river systems - Ohio, Mississippi, Tennessee, Cumberland, and Kentucky • Coal-Fired Power Plants • - CO2 production, metal deposition, thermal effluents • Coal Mining • - acid mine drainage, sedimentation, metals • Transportation • - habitat alteration, dredging, invasive species Ohio River western WV Slide courtesy of Charles Somerville, WV
