Nitrate and Groundwater Flow to Springs in the Upper Floridan aquifer, Lower ACF—Chipola Basin

by Christy Crandall

objectives of study 2007 through 2009
Objectives of Study—2007 through 2009

1) To quantify

  • groundwater travel times
  • areas contributing recharge
  • hydrologic and geochemical processes occurring along flowpaths

2) Test 3 nitrogen management scenarios from 2002 through 2050 in areas contributing recharge to Jackson Blue, Baltzell Group, and Sandbag Springs.

  • Cessation of nitrogen input after 2001
  • 4 percent decline per year of nitrogen input
  • Maintain nitrogen input at 2001 levels

future directions large objectives
Future Directions--Large Objectives
  • Develop linked groundwater/surface water model to calculate daily stage, stream flux, and head, as a function of pumpage, rainfall, upstream conditions, climate events, and dam releases through 2050
future directions my tasks
Future Directions—my tasks
  • Convert Current Model to transient flow model
  • Use more sophisticated unsaturated flow and streamflow routing to account for aquifer- stream interaction, evaporation and recharge in the surficial aquifer/residium.
  • Calibrate transient model for 1978 to 2008 recharge, stream and spring flow and pumpage conditions.
