streamflow analysis
Streamflow Analysis
  • Peak flow data from USGS
  • Graph results
    • 5 sites out of 20 increasing
    • 5 show evidence of channelization or regulation
temperature analysis
Temperature Analysis
  • US EPS STORET Data
  • 89 Locations in Metro Area

contaminant levels
Contaminant Levels
  • Nitrogen, Phosphorus, Bacteria
  • Data not readily available for long time periods
  • Data Sources:
conclusions
Conclusions
  • Urbanization has a marked, detrimental effect on water resources
  • Streamflow, temperature, and contaminant levels are likely to increase as urbanization occurs
  • Understanding the effects and their magnitudes can aid in mitigation efforts
