  1. The Effect of Wildfires on Water Quality from Watershed Systems of Southern California Presented to CE 394K.3 GIS in Water Resources Carolina B. Mendez November 16, 2010 www.americanobserver.net

  2. Wildfires • Increased erosion • Mobilization of particle-bound contaminants • Post-fire: watershed recovers • Accumulation of mercury observed 1 year after fire; mobilization of mercury noted during second season. (Burke et al., 2010) www.map.sdsu.edu

  3. Objective Use GIS tools to investigate the effect of wildfires on water quality from a watershed system in Southern California • USGS and USEPA data • CUAHSI HydroDesktop • ArcMap

  4. Fires in San Diego County

  5. Water quality: 1910 to 2010 Atrazine Total Organic Carbon Mercury Copper Lead Arsenic

  6. Water quality: 1960 to 2010 Atrazine Total Organic Carbon Mercury Copper Lead Arsenic

  7. Water quality: 1980 to 2010 Atrazine Total Organic Carbon Mercury Copper Lead Arsenic

  8. Water quality: 1990 to 2010 Atrazine Total Organic Carbon Mercury Copper Lead Arsenic

  9. 1980-2010 or 1990-2010 data set? Total Organic Carbon Mercury 1980-2010 1980-2010 1990-2010 1990-2010

  10. Attribute tables Fire Data Water Quality Data

  11. To-do List • Choose 1980-2010 or 1990-2010 data set • Locate watershed in San Diego County • Choose upstream and downstream gages • Correlate fire event to water quality data
